Hello. I have an issue with the Windows seven beta and the windows update. I try to update my windows seven, yet when the window pops up, it blanks oiut, and then another window pops up and it saws that windows explorer has stopped working, and then it restarts windows explorer. I have tried to restart but to no avail. Also, another issue is that when I try to install programs like rome total war and such, the installer stops working and I can't install or uninstall anything. please help me with this issue. thanks.

Have you tried to redownload and install the ISO?
