Well, I format my hard drive quite often.
Maybe you should figure out what the real fixes to your problems are instead of just reinstalling the OS. There's very few reaons to resort to a complete reinstall.
All I did was take out a harddrive add a video card and decided to reinstall. Then wamo I had to call MS to get it reactivated.
They asked me why I was reinstalling the OS..I paid for it, is it really any of their business??
You paid for the right to use MS' software and you agreed to their rules. You own nothing, and if they want to ask you why you want to reinstall or why you reboot every 3 days they can, because you agreed to it.
I have Corp maybe next time I'll just install that...
I can't wait until MS patches/Windows Update start disabling these systems, it'll be a real eye opener for a lot of people.
1) trojans - doubt it.
Why? It's warez, do you really trust those guys?
2) deactivation of windows via windows update? - doubt it...and even if so, who's going to update knowing that it disables your computer?...they'll catch how many people?...how many people will just reinstall the OS and not update?...big deal, let them deactivate via update...reality - they won't.
So the choices are run without any fixes or new MS software, or save some cash and "stick it to MS". With bugs like the UPnP ones out there, and surely more to be discovered, I think anyone with half a brain would just pay for the software.
