How many times have you reinstalled any Windows version on your computer(s)?

[Broni]

Windows 98 - twice; first time it was some total crash, and I didn't have any backup, so I lost everything; second time, on purpose - those pre-NT Windows were getting sluggish after some longer time of usage

Windows 2000 - once; when the computer in question became a secondary machine, I wanted a fresh start

Vista - once; 6 weeks young hard drive died; full backup was in place

I seem to remember having to reinstall Win2K about five times over the course of time I kept it on my system

hmm, let's see. With my 286, I had ot reformat, so I had to reinstall DOS 6 (does that count?)
my 386, I think I reinstalled 3.1 one time, but I'm not sure.

This PC, so far, I've reinstalled XP I believe 6 times, when it refused to boot from the HD.

I've reinstalled Vista on my laptop once. More or less an upgrade to ultimate and removal of the crapware manufacturers like to include.

I have installed xp a good couple of times myself.  It took me for ever to get it working right on my gaming machine.

I've done several reinstalls on my own and my friend's computers.
I guess I've probably done between 50 and 75 clean installs. I've done four clean installs on my girlfriends computer. That is probably the most I've done on one machine.

Several installs on my Vista computer (eMachines) that I bought a couple of years ago, and also installed Windows 7 Beta on it........ About 10 installs (while troubleshooting it) on my current XP computer, before I replaced the motherboard on it, but after I replaced the motherboard only two installs...

My intention was to find out only about your personal computer(s) only.

[hot dog]

oh, heh

note, I deleted installs that were not my own computers

I just edited the question, so it's more clear.

Desktop: XP Home, reinstalled once after major hardware change about a year ago.

Laptop: Vista Home Premium, reinstalled once as soon as I got it home. OS had a faulty factory install, been fine since reinstall.

Previously, on various systems: Windows 98, several times. Fedora, at least a few times. Windows 95, several times. DOS 6.22 and Windows 3.11... too long ago... more than a few times, much more.

Girlfriend's laptop: Windows XP Professional, 3 times in 3 years. Speaking of which, it's getting time for her to break her computer again.

I re-install my OS's about every 4 months...

[Broni]

Don't make anyone think, it's a norm

[patio]

Nope.
It's definitely OCD for sure...

I was going to say myself, I'm fairly as bad as he is but I like to run a clean machine when possible.  Like if a program ask to install acrobat 4 an I have seven why install a later version?

You mean install an earlier version?

Even though I haven't reinstalled Windows on my home system in a year, it still runs great. It all depends on regular maintenance and how much unnecessary stuff you run on your computer. Even my laptop with Vista runs well after 4 months.

I'm very picky about what goes on my computer, and anything I'm not using gets removed. I regularly defrag the hard drive, clear out the internet cache, and delete files I no longer want.
