I don't recommend doing a reinstall over the existing buggy OS. If that worked OK, you should really only need to use the update critcial files wizard.
But it don't tend to work, IMO.

Still leaves the bugginess.
Nothing like a fresh, fresh install!

Just save your data first.
Oh, and you could use the file and setting transfer wizard, but I'm a bit suspicious if that as well. I think it might carry over buggy DLL's and stuff (who knows
what it copies??

)
Anyway, that's my opinion.

BTW, my day is just fine. Win95 at work has only crashed twice so far.
