The WinSxS (Windows Side-by-Side) folder stores the necessary components for Windows to function properly. It includes:
- System Files: Essential files required for the operating system to run.
- Backups and Updates: Previous versions of system files and updates, allowing the system to revert to an earlier state if needed.
- Dependencies: Components needed for various Windows features and third-party applications to work correctly.
Why You Shouldn't Delete the WinSxS Folder
Deleting the WinSxS folder can cause severe system instability and may render your Windows installation unusable. This folder is integral for maintaining the integrity and functionality of your operating system, managing updates, and ensuring that all system components are available when needed.
How to Manage the Size of the WinSxS Folder
If you're concerned about the size of the WinSxS folder, there are safer ways to manage it without causing harm to your system:
- Disk Cleanup Tool: Use the built-in Disk Cleanup tool to safely remove unnecessary files.
