SysManager

A modern Windows system monitoring toolkit: live network monitoring with gamer-friendly presets, Windows updates, disk and memory health, gaming launcher cache cleanup, app updates via winget, performance tuning, battery health, process management with built-in descriptions, startup control, shortcut cleanup, app blocking, install alerts, and a friendly Event Log viewer — all in one WPF desktop app.

---

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 updates, 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.

⚙️ = 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.

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 Frankfurt, Vienna, Stockholm relays
  • FACEIT Europe — competitive CS2 servers in DE, UK, FR, NL, SE
  • PUBG Europe — Krafton EU matchmaking endpoints
  • Streaming — YouTube and Twitch ingest
• 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 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

Windows Update (via PSWindowsUpdate)

• Auto-check for the PSWindowsUpdate module on tab open, with a one-click install card if it's missing
• Sortable DataGrid table for available updates, hidden updates, and history
• Columns: Title, KB, Size, Status, Date, Category — click headers to sort
• Check for standard and feature updates
• Install selected updates, list history, check pending-reboot state
• Live console output in a collapsible panel during install operations
• Admin banner with a one-click "Run as Administrator" relaunch

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

• 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

• Two-pass scan: group by size, then SHA-256 hash only size-matched files
• 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

• Kill process with confirmation dialog
• Open file location in Explorer

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: 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

Download

Grab SysManager.exe 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.exe.sha256. Verify before running:

Get-FileHash .\SysManager.exe -Algorithm SHA256
# Compare the output to the contents of SysManager.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 SysManager
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.
