I currently have Windows 7 Beta, and I have a list of issues, here they are!

1) When I Open Windows Media Center or Windows Movie Maker, my computer freezes!
2) Windows Installer does not appear to be installed, and it gives error messages such as, the Error Number 2203.
3) The computer often freezes on startup, and can show a blue screen error. (Did Not Last Long Enough To Get The Error Message)
4) I cannot install or uninstall anything that uses Windows Installer
5) Cannot get Windows Sidebar to start.
6) Informational:- Could not start Mozilla Firefox 3.0.5, *FIXED*
7) Cannot use Windows Update!
8) AVG Firewall Driver couldn't work!
9) Get This Error:- The Windows Installer Service could not be accessed. This can occur if the Installer is not correctly installed. Contact you support personnel for assistance.

Also, I would like to know how to uninstall Windows Installer, and then install it again!
