Hi Talmaggies,
Thank you for posting in Microsoft Support Community.
The WinSxS folder is an essential component of Windows and contains all the files needed for Windows features, updates, and optional components. It is not recommended to delete or modify files in this folder manually as it can cause system instability and errors.
However, you can use the built-in DISM tool to remove unnecessary files from the WinSxS folder. To do this, open Command Prompt or Windows PowerShell as administrator and run
Dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase
