A system restore sounds like a good idea. You can do this with: 1. Restart your system 2. When the system first boots, type F8 to bring up the boot menu 3. Select the Safe Mode with Command Prompt option 4. Log-on as administrator if needed 5. At your command prompt type %systemroot%\system32\restore\rstrui.exe 6. Hit Enter 6. This will open the system restore wizard… However, I don't think that you will have a screen reader at that point. Sorry.
