GregOrigin Cleaner Suite is a transparent Windows 11 maintenance app for people who want practical cleanup, startup, service, and hardware tools without adware, subscriptions, or hidden background services.

It is built around native Windows tools and readable source code. The app favors preview, audit logs, backups, and allowlists over risky "one-click magic" optimization.

Most PC cleaners ask for a lot of trust. They promise speed, touch unclear areas of the system, and often hide their real incentives behind trials, ads, telemetry, or upsells.

GregOrigin Cleaner Suite takes the opposite approach:

• No registry "cleaning"
• No adware or sponsored installs
• No background service
• No telemetry
• No locked premium tier
• No proprietary driver
• Source code available in this repository

The goal is simple: give Windows users a focused maintenance dashboard that does useful work while staying understandable.

The recommended download is the standalone Windows executable from the latest GitHub release:

Download GregOriginSuiteApp.exe

Current final build:

Windows SmartScreen may warn that the app is from an unknown publisher because this release is not code-signed. If you trust this repository and want to run it, choose More info and then Run anyway.

Preview cleanup targets before deleting files.

• Analyzes Windows Temp, user Temp, Edge cache, Chrome cache, Prefetch, Windows Update cache, Recycle Bin, and selected advanced targets
• Writes a dry-run audit before cleanup
• Appends execution results after cleanup
• Keeps audit logs under %APPDATA%\GregOriginSuite\Audit
• Leaves registry cleanup out by design

Review and manage startup entries without losing a way back.

• Reads user and machine startup registry keys
• Reads startup folder items
• Reads logon/startup scheduled tasks
• Enables, disables, deletes, and restores entries
• Saves backups under %APPDATA%\GregOriginSuite\Backups

Work only with a curated service allowlist instead of exposing every Windows service.

• Shows service status, startup type, default recommendation, and reason
• Starts or stops selected allowlisted services
• Disables selected allowlisted services
• Saves restore data before startup mode changes

Quickly inspect the machine before doing maintenance.

• Shows CPU, RAM, GPU, and OS information
• Reads drive health status through WMI
• Scans C:\ for the top 50 largest files

GregOrigin Cleaner Suite is intentionally conservative where a cleaner app should be conservative.

• Cleanup has an Analyze step before deletion.
• Cleanup writes an audit log before and after execution.
• Startup and service actions create backups before destructive changes.
• Service management is limited to a curated allowlist.
• Privileged operations ask to restart elevated instead of silently failing.
• Registry cleaning is excluded because it is high risk and low value on modern Windows.

Some actions still modify the system. Read the on-screen prompts, review cleanup audits, and avoid advanced options unless you understand the consequence.

• Windows 11
• 64-bit Windows installation
• Administrator rights for protected cleanup, startup, service, and network reset operations

The app is built with .NET 8 WPF and published as a self-contained Windows executable.

Install the .NET 8 SDK on Windows, then run:

dotnet restore .\GregOriginSuite.slnx
dotnet test .\GregOriginSuite.slnx
dotnet publish .\GregOriginSuiteApp\GregOriginSuiteApp.csproj -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true -o .\final-publish

The WPF source is in GregOriginSuiteApp. The xUnit tests are in GregOriginSuiteApp.Tests. The original PowerShell edition is kept as GregOriginSuite.ps1 for transparency and historical continuity.

After downloading the release EXE, you can verify the hash in PowerShell:

Get-FileHash .\GregOriginSuiteApp.exe -Algorithm SHA256
