Hi @Brad,

If you are using Windows 10 1903 or later version of Windows 10. Then you can use Storage Sense feature which can automatically clean up all the temporary, windows update leftovers, and cache files. Storage sense is very effective and even it can run when your PC is on low disk space. In the Windows 10 version 1909 and Windows 10 version 2004 Storage sense has lot improved. So, I would strongly suggest you to use Storage sense on your PC to avoid unnecessary files fulling your disk. By default Storage sense is disabled on the PC, you have to enable it manually or through group policy or registry.

Please check this below topic to enable storage sense for your PC.
