My elderly brother-in-law was about to buy a new desktop because his was so slow. A daughter visited and found 27GB of stuff in his recycle bin!
The desktop is now perfectly fast enough for him.
And, that's just one of
many places that I would clean out!!! I used to do this stuff professionally, so I got pretty good at it.
My own "Cleanup.bat" batch file program is the culmination of 40+ years of cleaning up Computers, from PC's to Mainframes.
I only regret that it can't clean the Registry.
There is a tweak, that will load the registry into RAM on boot up. That can greatly speed up a PC that still uses a mechanical hard drive. That's not required for an SSD.
I've used that tweak for years, to get the most performance out of a PC that still uses an old mechanical HD.
Unfortunately, most users have no idea, that Windows will access the Registry several thousand times in a normal days work.
It's more difficult to access, and slower to read if it's bloated and fragmented.
That's why I try to keep my registry clean and defragmented. (or, loaded into ram when I'm running my SSD)
Everything I do to Windows to improve performance, was made possible by some Microsoft programmer.
Window has more back doors than a Walmart.
No one would dream of driving a 1/4 ton pickup truck around, with 1 Ton of rocks in the bed, but they will run a PC with thousands or even Millions of junk files in it. And then wonder why it's not running so good any more.
I used to clean up PC's for people, and get the comment "
WOW! It didn't run that fast when it was new!"
All I could say was, "
I know, it's what I do."

What would we do without your frequent reminders that we need to clean out the junk, that you offer all comers a batch file to do just that, and that Ghost, despite being from the middle ages, electronically speaking, actually still works?
