How to Use the Tool (The "Pre-Clean" Process)

Once you have downloaded the executable, follow these steps to clean your system:

1. Close All Applications: Ensure Visual Studio and any related programs are closed.
2. Run as Administrator: Right-click the downloaded .exe file and select Run as Administrator. This is crucial because the tool needs deep access to the registry and system files.
3. Select Your Version (If applicable): If you are using the generic cleanup tool, you will see a list of installed Visual Studio versions. Check the box next to Visual Studio 2012.
   • Note: Do not check versions you want to keep!
4. Execute: Click the Cleanup or Uninstall button.
5. Wait: The tool will scan and remove packages. This can take anywhere from 5 to 20 minutes depending on how cluttered your system is.
6. Reboot: Once the process is complete, restart your computer. This releases any locked files that were pending deletion.
