Pinger, I did the same upgrade from 7100 to 7127 as Mercurial. I didn't lose anything. Installed programs, docs, music, pics, etc, all worked fine. The one and only problem I encountered was a program called BW Meter, which is a bandwidth monitor. It freaked a little. But it was nice about it, just came up with a message saying to please reinstall it. Other than that, flawless.
Clean installs are always best. But I've done several upgrades also since 7000, The only major fail was 7000 32bit to 7022 32bit. The upgrade completely failed. I think it was do to an older version of AVG that I should have uninstalled prior to the upgrade. Even with the failure, Win 7 just rolled back to 7000 with no problems. Just a lot of wasted time.
The way I look at it now, I will try an upgrade, but before doing so, I make sure I'm prepared to do a clean install in case the upgrade really messes up. Everything is backed up first. MigWiz (Migration Wizard) helps a lot with that.
