I guess what was being referred to as the repair
install would wipe out all programs except the My Docs folder. It looks
like that info was not entirely correct.
I can understand the hesitation to completely rebuild from scratch but if a
repair leaves you with less than desirable results, you'll spend more time
trying to fix what broke during the repair with the real possibility of
doing a clean install to sort the mess out. It's really a matter of
personal choice as to where you're going to draw the line for amount of
effort and time spent for "possible" results vs the time needed to start
over from scratch.
I don't enjoy rebuilding from scratch either. When I adopted XP, I finally
looked into imaging software. There are many well known titles in this
software category, I chose Acronis True Image. It takes 5-10 minutes a week
to create an image. Another 5-10 minutes to "verify" that a usable image
was captured. If making major changes, an extra image is made just before
that happens. This means that if things go wrong, it takes me about 20
minutes to restore to a known good image. This sure beats the heck out of
rebuilding from scratch!
Just to reiterate, a repair install will wipe out old restore points and
all updates since the last service pack level you're at.
Good luck on whatever path you take and happy holidays to you too!
