README
SysManager
A modern Windows system monitoring and management toolkit: live network
diagnostics with gamer-friendly presets, Windows updates, disk and memory
health, gaming launcher cache cleanup, app updates and bulk install via
winget, performance tuning, privacy and telemetry controls, context menu
management, secure file shredding, DNS & hosts editor, duplicate finder,
battery health, process management with built-in descriptions, startup
control, shortcut cleanup, app blocking, install alerts, Windows features
toggle, 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 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.
Features
Sidebar navigation
The sidebar organises 55 feature tabs into 12 collapsible groups so you can
find what you need without scrolling through a flat list. 30 tabs are fully
implemented; 25 are work-in-progress placeholders marked with ⚙️:
Group
Tabs

> ⚙️ = 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)
HKCU fallback — system-protected entries can be toggled via user-level registry override

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

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

Toggle on/off without deleting the original entry (same mechanism as Task Manager)
Sort by name, publisher, or status via clickable column headers

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

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
Operation Lock

Live uptime counter
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.
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.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 SystemManager
dotnet run --project SysManager/SysManager/SysManager.csproj
The resulting SysManager.exe lands in publish/ and runs standalone on any
Windows 10 / 11 x64 machine.
First-time flow
Launch the app — it opens on the Dashboard.
Go to Network and press Start — live ping begins.
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.

contact the hosts you explicitly configure (ping targets, speed-test servers,
Windows Update / winget endpoints).
