I had Vista 64 bit Ultimate on my HTPC and I tried to install Windows 7 32 bit as a clean install, every time I get the new OS up and running I have no access to any programs. I click on Internet Explorer for example and I can see that it's open in the task manager, but no functionality whatsoever on the desktop. I thought this might be because some of my 64 bit system files were still in windows.old so I formatted my C drive before the last install. Same result. Any ideas why this might be? How I can fix it? Thanks in advance!
