Let me get this right.
You damaged the OS with CCleaner, overburden the service layer with AVG, try another 'free' tool to fix that by deleting some more stuff and hope to improve by erasing the Temp folder manually.
This may have worked in 2002 but even then actually didn't.
Most likely, apart from some crippling activity above, the system is trying to download and install the latest OS edition well above the pre-loaded one, and yes - even in 2022 this can get stuck.
Get help, not on pilot forums.

If your box don't have an SSD go buy one first, 128 will suffice, just about any.
