i remember when 8 was let out at preview stage i used it on my main pc. most said dont do it, i had no problems so i am about to do the same with '10'. i think its good enough
I would advise creating a backup of your current system and all data before going ahead. It just might save you a big headache if things don't go like you planned.
I did the same after doing system image and data backups. No major issues so far, just little things here and there like icons taking forever to populate, and Properties dialog not showing up until like 2 minutes after I click it.
every thing is always backed up so here we go
It's remarkably stable, especially for day 1 (running as main OS on desktop). Good luck
They said the same with 7 and 8 testing versions and I have used them as main OS for years, it was just an updated previous OS, just like 10 is only an updated 8.1, drivers and software mostly work, but sudden re-install can be expected, when something goes wrong, that is all to it.
I'm sure Vista's testing stage was horrific tho, considering that it was beary different from XP and XP drivers didn't work.
Indeed, no wonder people were considering Vista bad OS, nothing worked, I hated it at first too.
Even at release it was a nitemare. It was more resource intensive then XP (at launch, it was better by SP2), and it took a while for Nvidia/ATI to reach performance parity with XP in their drivers since Vista was so different. Plus some older devices never got Vista drivers (if manufactor stopped updating). MS obviously learned because they haven't done anything as radical as XP>Vista since then.
MS probably should've done a stopgap between XP>Vista at the time, but w/e Windows 7 saved us
I have done a test on my old laptop with the preview before I decided to do it on the live. The only thing that doesn't work for me is MediaPortal (but then again I don't think Media Portal worked in the Windows 8 Developer Preview anyway) - but luckly for me everything else works (files, programs that I use) and an alternative DVB Software "DVBViewer" works.
I would not have installed this on my main machine if there was any other hiccups with software compatibilities. One thing doesn't work and that's okay, at least I have a backup if I need :P
So far so good! :P
