Re: Sorry...
Yes, but...
I don't think I've ever risked actually fully upgrading a Windows OS in situ (installing service packs doesn't count), as the chances of finding out the new OS is either a) a total lemon or b) the 'upgrade' bricks the PC are just too high. I've always waited to change OS until I need a new laptop/PC - which happens every 4-5 years. In this case my Win 7 box is 4.5 years old, and should be good for at least another 18 months (possibly with an upgrade to an SSD). Then I'll (probably) get a nice new machine with Win 10 pre-installed, and take the opportunity to clean out all the crap as I migrate data and essential software.
It's a strategy that works for me - I've never owned a copy of Win 3.0, ME, Vista or Win 8!
