Installing Windows 7
I've been running Windows 7 RC on my Aspire One netbook without problems.
Tonight I installed the newly arrived Windows 7 Professional. Since it could not upgrade the Ultimate RC version, the old system was placed in a Windows.old directory and a new copy installed. The install involved quite a few restarts, but went fairly fast until it got to the finishing stage and that took much longer than all the rest put together.
What I finally got was Windows 7 with US settings and IE installed and no option to install other browsers. Switching to UK settings was easy.
I then tried to customise the install as I don't like blue. But I kept running into missing files and bad URLs on the Microsoft website.
I also made the mistake of trying to delete the Windows.old directory. First the system counted the files and moaned about some names being too long for the Recycle Bin. Then it started to delete them, about 110,000 files and 6.5GB. Half an hour later it is still deleting them. Not much disk activity and no indication how far it has got...
So far it has been a much less pleasant experience than installing the RC.
Added following a tweet from Steve Rumsby: I'd recommend anyone about to upgrade to read this report from the BBC's Tim Webber first.
