Smart Scan Advanced is producing an error

When I run the Smart Scan, I get the message that 23450 performance issues were found. System junk 5219 MB, Broken registry items 435, Programs slowing the computer: 18, Internet junk files 3077.

I performed a Disk Cleanup, I went to system settings and deleted internet and system junk files, and I restarted my PC.  I ran the Smart Scan again, and the results were EXACTLY the same. I contacted support, and they wanted to sell me more product.  I asked them to produce the detail behind each summary item, and they refused to do so.  How can I see the detail behind the summary of performance issues?

Hello Donald. The simplest solution is, don't use that scan. Windows 10 & 11 do a great job of keeping files cleaned from a system. It is much like Software Updater, DON'T use it. They are both marketing driven and not mature features at this point. I also wouldn't even consider using NU for those reasons as well. Its a waste in my opinion and causes other issues.
