What it is

SysManager is a local-first desktop tool for keeping an eye on a Windows PC. It rolls network diagnostics, system health, Windows Update, app management (updates, bulk install, uninstall), privacy controls, context menu management, secure file shredding, driver inventory, safe deep cleanup, and a readable Event Log viewer into a single tabbed WPF app.

Everything runs on the machine itself. No cloud, no telemetry, no account.

Built with gamers in mind — live ping overlays for CS2, FACEIT, PUBG and streaming endpoints, Steam/Epic/Battle.net/Riot/GOG/EA launcher cache cleanup, and an honest "is it my PC, my ISP, or the server?" verdict.

Why SysManager?

Most Windows utilities do one thing, or bundle telemetry and upsells. SysManager is a single, local-first app that covers the whole maintenance surface — and it's fully open source.

⚙️ = Work in Progress — placeholder tab visible in the sidebar, implementation coming in future updates.

Groups expand and collapse with a click. Collapsed groups show a child count badge, a subtitle with abbreviated child labels, and a tooltip with the full list. Dashboard renders as a flat top-level entry without an expander arrow. Each tab shows a slim progress bar under its name when performing a long-running operation, so you always know which tab is working.

Theme customization

A palette button in the top-right corner opens an appearance popup with:

• Dark mode — 6 curated presets (Midnight Indigo, Deep Ocean, Dark Forest, Neon Rose, Violet Night, Warm Ember)
• Light mode — 6 curated presets (Clean Indigo, Sky Breeze, Warm Sand, Mint Fresh, Soft Blossom, Lavender)
• Custom mode — free hex input for accent, background, surface, and text colors
• Background shade slider for fine-tuning lightness/darkness
• Settings persist between sessions

Context Menu Manager

Manage Windows Explorer right-click entries — toggle them on or off without deleting anything (uses the standard LegacyDisable registry mechanism):

• Presets: Win10 Default (classic full menu), Win11 Default (modern compact), Custom
• Selecting a preset resets to clean defaults, disabling third-party entries — re-enable individually
• Win10/Win11 style toggle — switch between classic and modern menu (restarts Explorer)
• Visual preview on hover — real screenshots of each menu style
• Entry explanations — human-readable descriptions for common entries
• "Applies to" column — shows whether entry affects Files, Folders, Desktop, or Directory Background
• HKCU fallback — system-protected entries can be toggled via user-level registry override
• Admin elevation banner with one-click restart as administrator

Environment Variables

Edit Windows environment variables without the cramped built-in dialog:

• User and System scopes in one grid — filter by scope, search by name or value
• In-place value editing, plus add and remove variables
• Dedicated PATH editor for PATH-like variables — reorder directories, remove entries, and strip duplicates in one click
• Missing folders highlighted so you can spot dead PATH entries at a glance
• Local until Apply — changes are staged; a one-time JSON backup of every variable is written before the first write so the original environment is recoverable
• Changes broadcast to Windows, so new terminals pick them up without a reboot
• System-scope edits need administrator rights (standard elevation banner); user variables can be edited without it

Network monitor

• Live ping across multiple targets overlaid on a single latency chart
• Auto-verdict that tells you in plain English whether packet loss is local, at your ISP, or at the far-end service
• Presets for gamers & streamers:
  • Global (Google, Cloudflare, your router)
  • CS2 Europe — Valve matchmaking relays (Vienna, Luxembourg, Warsaw, EU West/Central/East)
  • FACEIT Europe — competitive CS2 servers in DE, NL, UK
  • PUBG Europe — EU matchmaking cloud regions (Frankfurt, Ireland, London)
  • Streaming — YouTube, Twitch, Cloudflare
• Auto-traceroute on a configurable interval (30 s – 10 min)
• Speed tests: HTTP (Cloudflare) and the official Ookla CLI (auto-downloaded) with persistent history (last 20 results per engine) for tracking service degradation over time
• Jitter, loss %, and average ping per target rolled up into health pills
• Network repair tools: DNS flush, Winsock reset, TCP/IP reset with confirmation dialogs and admin checks

System logs (Windows Event Log, friendly)

• Browse System, Application, Security, and Setup logs
• Each event gets a plain-English explanation and recommended next steps
• Filter by severity and time range, plus full-text search
• Export to CSV, with a "search online" link for unknown events

System report

• One-click, read-only snapshot of the whole machine: OS, CPU, memory (with per-slot module detail), GPU, motherboard, storage health, and active network adapters
• Storage section carries SMART detail when available — temperature, wear %, and power-on time — reusing the same disk-health data as the System Health tab
• Export as plain text, a styled self-contained HTML page, or structured JSON — or copy the text straight to the clipboard
• Fully local: nothing on the system is changed and the report is written only to the file you choose — nothing leaves the machine

System health

• OS / CPU / RAM / storage overview
• SMART data per disk: temperature, wear %, power-on hours, read/write errors
• Colour-coded verdict per drive
• Memory diagnostic that scans the last 30 days of WHEA events for RAM errors
• Schedule the Windows Memory Diagnostic at next boot
• Read-only chkdsk with auto-discovered NTFS/ReFS drives and multi-select
• BIOS & firmware — BIOS version/date/vendor, motherboard model, boot mode (UEFI/Legacy), and Secure Boot status, all read-only. A Find BIOS update button opens the right manufacturer support page (ASUS, MSI, Gigabyte, ASRock, Dell, HP, Lenovo, …) for the detected board, and Copy info grabs the model + BIOS version for support searches. SysManager never flashes firmware itself.

Restore Points

• List every Windows System Restore point — sequence number, date, description, and type — newest first
• Create a restore point with an optional custom description (enables System Restore on the system drive first if it's off)
• Restore the PC to a selected point, with a clear confirmation that warns Windows will restart and that programs/drivers added since that point are removed
• Admin elevation banner — viewing the list works unprivileged; creating and restoring need administrator rights

Legacy Panels

• One-click launcher for the classic Windows applets that newer releases keep hiding: Control Panel, Sound, Power Options, Network Connections, Region, System Properties, User Accounts, Device Manager, Computer Management, Programs and Features, Mouse, and Date and Time
• Pure launchers — each just opens the built-in panel; nothing is modified, so no elevation or confirmation is needed
• The applet list is fixed in code, so no typed input ever reaches the launcher

System Fixes

One-click repairs for common Windows breakages, each with a clear description and a confirmation before it runs:

• Reset Windows Update — stop the update services, clear the SoftwareDistribution and catroot2 caches, and restart the services
• Reinstall WinGet — re-register the App Installer when app installs/uninstalls fail
• Set up Auto Sign-in — opens the built-in User Accounts dialog, so Windows stores the credential securely and SysManager never handles your password
• Live output, honest success/failure reporting, admin elevation banner
• Network-stack reset (Winsock / TCP-IP / DNS flush) lives on the Network → Network Repair tab, which offers those as individual one-click tools.

Boot Analyzer

• Shows how long your PC takes to boot — total, core (main path), and desktop ready-up time — across recent boots, read from the Windows boot-performance history (Diagnostics-Performance log)
• A trend line tells you whether the last boot was faster or slower than your recent average
• Lists the apps, drivers, services, and devices Windows flagged as slowing boot, with the delay attributed to each
• Read-only; reading the log requires administrator (elevation banner shown)

Windows Update (Windows Update Agent COM API)

• Direct Windows Update Agent COM integration (Microsoft.Update.Session) — installs everything WUA can offer, including optional drivers and firmware that PSWindowsUpdate filters out client-side
• Unified DataGrid for everything in one scan — standard, feature upgrades, optional drivers, and hidden updates
• Categorized with colored pills: Security, Cumulative, Defender, Driver, Servicing, .NET, Feature upgrade, Hidden — click headers to sort
• Per-update checkbox selection with Select all / Deselect all — install exactly what you want, skip what you don't
• Live progress per update: Connecting → Downloading → Installing → ✓ Installed streamed to the console as it happens
• Per-row Status column updated in real time (Pending… → Downloading… → Installing… → Installed / Installed (reboot required) / Failed / Not applied)
• Honest aggregate reporting: Installed X/Y. Failed: Z. Not applied: W.
• Reboot detection — toast notification if any update requires reboot
• Pending-reboot check, update history (last 30 — via PSWindowsUpdate)
• Admin banner with a one-click "Run as Administrator" relaunch
• PSWindowsUpdate is optional now (used only for the History view)
• Update timing & deferral — defer feature updates by N days while security patches keep flowing, pause all updates for a bounded window (max 35 days, then Windows auto-resumes), or restore defaults. Uses the documented Windows Update policy keys and is fully reversible. No "disable updates forever" option by design — the strongest action is a bounded pause, so the machine is never left permanently unpatched.

App updates (winget)

• Scan for upgradable packages
• Sort by name, ID, version, or source via clickable column headers
• Select all or individual packages, bulk upgrade with per-package status

Cleanup (fast)

• Clear TEMP folders
• Empty the Recycle Bin
• Run SFC /scannow and DISM /RestoreHealth in the background — keep using the app while they grind

Deep cleanup (safe)

• Scan-first: every category is discovered with size + file count before a single byte is deleted. You pick what goes.
• System buckets: NVIDIA / AMD / Intel installer leftovers, Windows Update cache, Delivery Optimization cache, Windows Installer patch cache, TEMP, Prefetch, crash dumps, old CBS logs, DirectX shader cache, Recycle Bin on every drive.
• Gamer buckets — launcher caches only, never game files or logins: Steam (appcache, htmlcache, depotcache, shader cache), Epic Games Launcher, Battle.net, Riot / League of Legends, GOG Galaxy, EA Desktop.
• Windows.old is detected and flagged as irreversible, never selected by default.
• Safe by design: never touches browsers, passwords, the registry, active drivers, or actual game files. Locked files are skipped, never forced.

Large files finder (part of Deep Cleanup)

• Scan Downloads, Documents, Desktop, Videos, Pictures, Music, Program Files, or a whole drive.
• Configurable min-size (default 500 MB) and top-N (default 100).
• Read-only — only "Show in Explorer" and "Copy path" actions. Deletion is disabled by design so a mis-click can never hurt anything.

Startup Manager

• Lists every program that runs at Windows boot (Registry Run / RunOnce keys)
• Toggle on/off without deleting the original entry (same mechanism as Task Manager)
• Sort by name, publisher, or status via clickable column headers
• Shows name, publisher, command, and enabled/disabled status
• Open file location in Explorer

Windows Features

• Lists all Windows optional features with current state (Enabled/Disabled)
• Toggle enable/disable per feature with confirmation dialog
• Categorized: Virtualization, Networking, Development, Media & Print, Legacy
• Shows reboot-required status after toggling
• Search/filter across all features
• Requires administrator privileges for modifications

Duplicate File Finder

• Three-pass scan: group by size, partial-hash pre-filter, then full SHA-256
• Duplicate groups sorted by wasted space (descending)
• Preset folders or custom folder selection
• Configurable minimum file size filter
• Read-only — "Show in Explorer" and "Copy path" only, no delete

Disk Analyzer

• Space breakdown by top-level folders with drill-down navigation
• Drive usage bar with total/used/free
• Preset paths (fixed drives, user profile, Program Files) or custom browse
• Show in Explorer for each folder
• Skips system paths automatically

Process Manager

• Lists running Windows processes with PID, memory, threads, and status
• Real-time filter by name, description, category, or PID
• Sort by memory, CPU usage, name, or PID via clickable column headers
• Built-in description database — 108 common Windows processes and popular applications with plain-language descriptions, categories (System, Browser, Development, Communication, Media, Gaming, etc.), and safety indicators (System, Trusted, Unknown)
• Kill process with confirmation dialog
• Open file location in Explorer

Camera/Mic/Location

• Shows which apps recently used your camera, microphone, or location, and when
• Reads the Windows access history (CapabilityAccessManager consent store) — covers both Store apps and desktop programs
• Devices in use right now are flagged and sorted to the top
• Read-only: an Open privacy settings button hands off to Windows to grant or revoke a permission — SysManager never changes capability permissions itself

Operation Lock

• Prevents conflicting concurrent operations across tabs
• Operations grouped by category (Disk, Network, SystemModification)
• If a conflicting operation is already running, the UI shows which operation is blocking and refuses to start the new one
• Integrated into: Dashboard, Deep Cleanup, Disk Analyzer, Duplicate Finder, Quick Cleanup, Speed Test, Traceroute, Network Repair, Shortcut Cleaner

Shortcut Cleaner

• Scans Desktop, Start Menu, Quick Launch, and Recent Items for broken .lnk shortcuts whose targets no longer exist
• Lists results with name, location, and missing target path
• Select all / deselect individual items
• Move to Recycle Bin or permanent delete, with confirmation dialog
• COM-based IShellLink resolution for accurate target validation

Privacy & Telemetry

• 12 registry-based toggles across 3 categories (Telemetry, UI Declutter, Features)
• Telemetry: disable diagnostic data, activity history, advertising ID, feedback prompts
• UI Declutter: disable Start suggestions, tips, lock screen tips, Spotlight ads
• Features: disable Copilot, Cortana, web search in Start, widgets
• Explicit apply — flip toggles to stage changes, press Apply to write to the registry, or Discard to revert pending changes. A live counter shows how many changes are queued, so accidental clicks never modify the system silently.
• Category filter and search
• Requires admin for HKLM-backed toggles
• Fully reversible — re-enable any toggle with one click

File Shredder

• Secure multi-pass file and folder deletion beyond recovery
• Three shred methods: Quick (1 pass, zero fill), Standard (3 passes), Thorough (7 passes)
• Cryptographically random overwrite data (RandomNumberGenerator)
• Add files or entire folders via file picker dialogs
• Progress tracking per-item with cancel support
• Skips junction points and symbolic links (prevents symlink attacks)
• Confirmation dialog before irreversible shred

DNS & Hosts

• DNS Preset Switching — one-click DNS change: plain resolvers (Google, Cloudflare, Quad9, OpenDNS) plus ad/malware/family-blocking variants (Cloudflare 1.1.1.2 malware / 1.1.1.3 family, AdGuard DNS ad-blocking + family, OpenDNS FamilyShield), each with a description of what it blocks. IPv6 resolvers are configured automatically alongside IPv4. Reset to automatic (DHCP) any time; shows current active DNS. An Undo button restores the exact DNS configuration in effect before the last change.
• Hosts File Editor — view, add, and remove entries from the Windows hosts file with a clean table UI. Add IP + hostname pairs, toggle entries, or remove them. Backs up hosts file before modifications.
• Requires administrator privileges for both DNS and hosts operations
• Admin elevation banner with one-click restart

Bulk Installer

• Curated catalog of popular applications grouped by category: Browsers, Communication, Media, Development, Utilities, Gaming, Security, Office & Productivity, Creativity, Networking & VPN, Runtimes & Frameworks

• Live console output showing winget progress
• GroupedView with visual category headers

App Alerts

• Monitors Program Files, AppData\Programs, and registry uninstall keys for new application installations
• FileSystemWatcher on install directories + 30-second registry poll cycle
• Shows timestamped install history with app name, publisher, path, and detection source
• Start/stop monitoring, acknowledge alerts, show all currently installed apps, clear history

App Blocker

• Blocks applications from executing using Image File Execution Options (IFEO) registry mechanism
• Enter an exe name or browse for a file, confirm, and the app is prevented from launching
• Fully reversible — unblock restores normal execution
• Shows list of currently blocked apps with select/deselect and batch unblock
• Requires admin privileges for registry modifications

Debloater & Ads

Remove preinstalled Windows Store apps you don't use:

• Scan all installed Store apps with name, publisher, and a short description
• Curated "common bloat" preset pre-selects safe, frequently-removed apps (Bing News/Weather, Clipchamp, Solitaire, Xbox apps, consumer Teams, and more)
• System-critical apps are protected — the Store, frameworks, and security/shell components are denylisted and can never be selected or removed
• Impact summary + confirmation before anything is uninstalled
• Reversible — removal is per-user, so any app can be reinstalled from the Store
• Search and per-app descriptions help you decide before removing

Browser Cleaner

Reclaim space and clear browsing traces, per browser:

• Auto-detects Chrome, Edge, Brave, Opera, and Firefox
• Per-category with size shown: Cache, History, Cookies, Sessions
• Cookies/sessions are flagged and left unticked by default — cleaning them signs you out, so it's always an explicit choice; cache and history are pre-selected
• Confirmation with an impact summary before anything is deleted
• Per-user (no admin); locked files (browser open) are skipped, not forced, and symlinks/junctions are never followed

Battery Health

• Charge %, health %, wear level, cycle count, chemistry

• Power Plan: Balanced / High Performance / Ultimate Performance
• Visual Effects: reduce animations via P/Invoke (instant, no logout)
• Game Mode: enable/disable via registry
• Xbox Game Bar: disable overlay and Game DVR via registry
• NVIDIA GPU: force max performance with auto-detected GPU subkey (reboot required)
• Processor State: force CPU min state to 100%
• Overlays info: manual instructions for Discord, Steam, NVIDIA GFE, EA App
• OriginalSnapshot: captures exact system state before first change; Restore All reverts to the snapshot, not hardcoded defaults
• Confirmation dialog before every change
• Restore point creation: create a Windows System Restore point before making changes (requires admin)
• RAM working set trim: free physical RAM by trimming all process working sets — same as RAMMap's "Empty Working Set" (useful before launching a game)
• Hibernation toggle: enable/disable hibernation to free disk space (deletes hiberfil.sys when disabled)

Services

• Lists all Windows services with current status and startup type
• Gaming recommendations: services tagged as "safe to disable", "advanced", or "keep enabled" with per-service explanations
• Filter by status (Running/Stopped), recommendation level, or free-text search
• Start, stop, disable, or enable services with confirmation dialogs
• Requires admin for all mutations

Drivers

• Sortable DataGrid table of all installed system drivers

Dashboard

• One-line OS / CPU / RAM / disk summary
• Live uptime counter
• Real-time vitals — CPU, RAM, and GPU usage refreshed at 300 ms while the tab is visible (polling pauses automatically when it isn't), with live indicator dots.
• Recent Activity — the last few actions you ran (Quick Cleanup, Update All Apps, Check Updates, …) with timestamps.
• Quick Tune-Up — one-click wizard that cleans temp files, optionally empties the Recycle Bin, scans for broken shortcuts, checks disk SMART health, flags high uptime (14+ days) and high RAM usage (85%+). Displays a summary card with freed space, warnings, and links to relevant tabs. Non-destructive, no admin required.
• Health Score — overall system health gauge (0–100) combining disk SMART, RAM usage, uptime, and battery wear. Color-coded ring (green / amber / red) with up to 3 actionable recommendations. Auto-computes on load and refreshes with "Scan system".
• System Tray — minimize-to-tray on close, background health monitoring (60s polling), CPU/RAM tooltip, Windows notifications when RAM > 90%, uptime > 14 days, or disk health degrades. Context menu: Show / Exit.

Updates (for SysManager itself)

• Auto-check on startup against the GitHub Releases API, plus a manual "Check for updates" button in the About tab.
• Discreet banner in the main window when a newer version is available.
• Background download of the new build with a progress bar. If the download is blocked, a "Manual download" button opens GitHub in the browser.
• SHA256 hash verification before install — blocks corrupted downloads.
• One-click "Install" replaces the running executable in-place and restarts automatically (no manual file copying needed).
• Full release-note history pulled live from GitHub.

Profile Export / Import

• Export your SysManager settings — theme/appearance and speed-test history — to a single portable JSON file, and import them on another PC
• Selective export (tick which sections to include) and selective import (confirm what a profile contains before anything is overwritten)
• Version-aware — refuses profiles created by a newer, incompatible build
• Only SysManager's own config is ever touched (never system settings), so an import is fully reversible — just import a different profile

Install

Via winget (recommended)

SysManager is published to the Windows Package Manager community repository. Install or update with a single command:

winget install laurentiu021.SysManager

Updates are delivered automatically with each release — run winget upgrade to stay on the latest version.

Direct download

Grab SysManager-v<version>.exe (the <version> shown on the latest release) from the latest release and double-click it. The executable is self-contained — no installer, no .NET runtime required.

Verifying the download

Each release ships a matching SysManager-v<version>.exe.sha256. Verify before running (replace <version> with the version you downloaded):

Get-FileHash .\SysManager-v<version>.exe -Algorithm SHA256
# Compare the output to the contents of SysManager-v<version>.exe.sha256.

The build is not currently code-signed, so Windows SmartScreen may warn on first launch. Verifying the SHA256 matches the one on the release page is the recommended mitigation — see SECURITY.md for details.

Build from source

Prerequisites: Windows 10 or newer and the .NET 10 SDK.

git clone https://github.com/laurentiu021/SystemManager.git
cd SystemManager
dotnet run --project SysManager/SysManager/SysManager.csproj

Produce a single-file exe

From the repo root:

.\publish.ps1

Or manually:

dotnet publish SysManager/SysManager/SysManager.csproj `
  -c Release -r win-x64 --self-contained true `
  -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true `
  -o publish

The resulting SysManager.exe lands in publish/ and runs standalone on any Windows 10 / 11 x64 machine.

First-time flow

1. Launch the app — it opens on the Dashboard.
2. Go to Network and press Start — live ping begins.
3. For anything in Windows Update, Cleanup (SFC/DISM), or system-wide App updates, click the yellow "Run as Administrator" banner when it appears. The app relaunches elevated.

• Serilog for structured logging
• xUnit, NSubstitute, and FlaUI for unit, integration, and UI-automation tests

Privacy

SysManager runs entirely on your machine. It does not phone home, does not collect telemetry, and does not require an account. Network features only contact the hosts you explicitly configure (ping targets, speed-test servers, Windows Update / winget endpoints).

Contributing

PRs welcome! Please read CONTRIBUTING.md for the build setup, coding conventions, and pull-request workflow. New contributors are expected to follow the Code of Conduct.

Support

SysManager is free and open source, built by one person in their spare time. If it saved you a reinstall or a clean-up headache, you can back its development:

Sponsorships go toward a code-signing certificate, so Windows stops warning on first launch, plus the build pipeline and time to fix bugs and finish the tools that are still half-built. The app stays free either way.
