Windows PCs can easily fill up with clutter that consumes valuable space, slowly affecting performance. The WinSxS folder is one location that holds many useless files that can be deleted to free up space on your computer.

However, how do you go about it, and is it even safe to do so? This article will explain how to clean the Winsxs folder in Windows 10.

Read on to learn.

What Is the WinSxS Folder?

WinSxS stands for side by side, as the folder contains different file versions stored together. It also contains crucial components to help update and customize the operating system.

So, it has the files involved in switching editions, recovering missing or damaged system files, adding or removing features, etc.

Can I Remove WinSxS On Windows 10?

You’re probably asking yourself, “Is it safe to delete WinSxS?” Well, deleting this folder would be a bad idea because the operating system needs the crucial components in it.

Therefore, deleting it would make it impossible for the operating system to perform some operations and cause problems. Windows update and booting issues are among the consequences you may experience.

However, the WinSxS folder also stores older operating system versions to make it easier to roll back. It does this with every system update, meaning it gets bigger over time.

Deleting these files would help free up space on your machine.

Windows 10 automatically scans this folder for the files it no longer needs and deletes them. However, you can manually delete the useless files if your PC runs out of space.

How to Check the Size of the WinSxS Folder

Windows allows you to check how much space the WinSxS folder uses on your PC. Follow these steps to do so:

  • Use the Windows key + S combination to open the Windows search bar.
  • Type in command prompt and right-click the Command Prompt search result.
  • Choose Run as administrator.
  • Click the Yes button once the User Account Control prompt box appears.
  • When the elevated prompt appears, type in the following command and then hit Enter:
dism /Online /Cleanup-Image /AnalyzeComponentStore
  • Wait for the process to finish. The WinSxS folder’s size is under the Actual Size of Component Store section.
