We like Windows 7: it's faster than Vista, makes better use of your system resources, is packed with interesting features, and looks great, too. But that doesn't mean it's perfect, of course. If you've moved to Windows 7 recently then you might have noticed various upgrade problems, interface issues and features that seem to have disappeared entirely, among many other complications with the new system.

Don't despair, though - while these problems can be really frustrating, answers are beginning to appear. We've uncovered some of the best and most effective solutions around, so follow our guide and your Windows 7 installation will soon be back on track.

1. Vista upgrade hangs at 62%

Windows 7 can start causing problems before it's even installed, as many people report their upgrade hangs forever at 62%. Which is annoying.

Reboot, and your PC should roll back to Windows Vista. You can then open the setup log file \$WINDOWS.~BT\Sources\Panther\setupact.log to view what happened. Microsoft say this is usually caused because the Iphlpsvc service has stopped responding, and just adding an environment variable to ignore it will fix the problem. Point your browser at http://support.microsoft.com/default.aspx/kb/975253 for the fix.

If this doesn't help (or your upgrade hangs at something other than 62%) then browse the setup log for other clues. And you might also try to boot and install from the Windows 7 disc, if possible, as that reduces the chance of any conflict with your existing Vista (or XP) setup.
