Installed it on my desktop using a spare hard drive. At first the screen resolution was ridiculously low despite the fact that it had automatically installed the correct graphics card drivers. After about 10 mins it seemed to just correct itself automatically. Then windows update popped up to tell me that my wifi card drivers were out of date. (Surely the latest drivers should be supplied with the latest os?). So anyway, I installed the update and after a restart it told me there were no wireless networks found. (before the update and in Win 7 it detects at least 6 networks.) So I tried to do a driver roll back for it to totally crash and restart the entire machine. I've not bothered any more since then and just booted back into 7.
