DeskStat

See what's slowing your Windows 10 or 11 PC down, and how to fix it.
Download DeskStat

DeskStat is a small Windows app (one 3 MB .exe) that checks your PC in a few seconds and explains what it finds in plain English. It looks and behaves like the built-in Windows 11 apps: it follows your light or dark theme and your accent color.

What's inside

• Overview: your PC at a glance, what needs attention, and live processor, memory, disk and network graphs.
• Health check: every check, worst first. Select one to see what to do, with a button that opens the right Windows setting.
• Performance: live graphs laid out like Task Manager.
• Running apps: what's using your memory and processor, with browsers and other multi-process apps grouped into one line.
• Startup apps: everything that opens when you sign in.
• Storage: space on every drive, how big your temporary files and Downloads folder are, and the cleanup tools.
• System info: processor, memory sticks, graphics, drives (SSD or HDD, and their health), Windows version, battery. One click copies it all.
• Tips: 28 safe tips, searchable, for speed, startup, storage, updates, security, gaming, battery and troubleshooting.
• Save report: a text file of the results on your desktop, handy when asking someone for help.

What it checks

Nearly full system drive · high memory use or less than 8 GB installed · busy processor · too many startup apps · gigabytes of temporary files · large Downloads folder · Storage Sense off · no restart in days · restart needed to finish updates · Power saver plan on a plugged-in PC · Windows on a hard disk (HDD) · a drive reporting bad health · Windows 10 (free security updates ended October 14, 2025) · animations on a low-spec PC · a single app (like a browser) using a lot of memory.

Safe by design

• Read-only. DeskStat never deletes files, edits the registry or changes settings. Buttons open the matching Windows page or tool so you stay in control.
• Private. No account, no tracking, works offline.
• No admin rights needed to install or run.

Install

1. Download DeskStat-Setup-x.y.z.exe from Releases.
2. Run it. Keep Desktop shortcut ticked if you want an icon on your desktop.
3. Open DeskStat from the desktop or the Start menu.

No install wanted? Download DeskStat-x.y.z-portable.zip, unzip it and run DeskStat.exe.

"Windows protected your PC"? Windows shows this for new apps that aren't code-signed. Select More info → Run anyway. The source code is all here, and every release is built by GitHub Actions from this code (see the Actions tab).

Requirements: Windows 10 or 11, 64-bit. DeskStat uses the Microsoft Edge WebView2 Runtime, which comes with Windows 11 and up-to-date Windows 10. If it's missing, DeskStat offers to open the download page.

Uninstall: Settings → Apps → Installed apps → DeskStat → Uninstall.

Build it yourself

You need Go 1.24+. For the installer you also need NSIS.

On Windows:

winget install GoLang.Go NSIS.NSIS
.\build.ps1 -Version 1.0.0

On Linux or macOS (cross-compiles the Windows .exe):

sudo apt install nsis zip            # or: brew install makensis
./build.sh 1.0.0

Output is in dist/: DeskStat/DeskStat.exe, the portable zip and DeskStat-Setup-1.0.0.exe.

To work on the interface on any OS, run go run . -serve and open http://127.0.0.1:8765. It uses sample data.

Releasing a new version

git tag v1.0.1
git push origin v1.0.1

GitHub Actions tests DeskStat on a real Windows machine, builds the .exe and installer, and publishes them as a Release.

How it works

File	What it does
main_windows.go	Opens the window (WebView2) and passes requests between the interface and Go
collect_windows.go	Reads the system: Windows APIs, performance counters, registry, and one PowerShell query for hardware details. Read-only.
advisor.go	Turns the results into recommendations (tests in advisor_test.go)
tips.go	The Tips library
actions.go	The Windows settings pages and tools the buttons open
ui/	The interface (HTML, CSS, JavaScript), built into the .exe
installer/deskstat.nsi	The installer, with the desktop shortcut option
winres/	App icon, manifest and version info

New checks go in advisor.go, new tips in tips.go. Pull requests are welcome.
