This is what inevitably happens to every computer running the
Microsoft Windows family of
operating systems. Once your computer has been running for a while, the registry and filesystem gets so full of useless junk from old programs and bloatware, that it slows the whole system down. After you've defragged
a million times and cleaned up everything imaginable, you still can't get your computer back to the way it was when you first installed Windows. The only cure is to reinstall a fresh copy of the operating system. That will keep you going for at least another 3 months.
Man, my system is so winrotted,
I can't do a damn thing
with it.
My
computer has winrot so bad, even Doom won't run on it!
