I was floored to realize how much faster things were. No wait time for a Windows Explorer window to open. Everything was snappy, even after reinstalling games and antivirus. It blew my mind.
I still think it helps, but with a much longer tail on the frequency required. Windows XP definitely grew slow over time though, whether that was due to installing programs, caches I could’ve cleared with CClearner, or more incremental updating. We leave a lot on the OS over time.
The very first time I reinstalled WinXP was shortly after I got my first computer of my own for my 12th birthday. I was tinkering with some of the files, and discovered that I could open .cur cursor files in MS Paint. I edited one of the cursor files, saved it as a bmp and renamed the file to .cur under the assumption that this would work. Set my custom cur file as cursor and logged out. When I tried to log back in I couldn’t. Whoops. Freaked out for a second thinking I had broken everything. Remembered that there was a red floppy disk with an ambulance on it that came with the computer. Rebooted the machine with the red floppy disk and reinstalled Windows. Lost my files but had nothing valuable at the time anyways. Have lost more valuable data since then. And expect to lose more data in the future still :p
So I put the disk in, and it says something like "Do you want to install Lindows?" with no options, no warnings or anything. So I hit Yes/Okay/whatever the single button on the screen was, and without zero warning, it proceeded to wipe my entire hard drive.
It's been 17 years and it still hurts :)
