I have a problem with my Win 7 x64 SP1 pc.I've uninstalled the Office with the Revo Uninstaller and then it becamess very unstable.I've tryed to do go back to a restore point, but I get errors and I don't have a backup.The problems I have are: 1. The Windows explorer don't work. It says: Explorer.exe There is not enough memory to run this program2. The Control Panel don't work. The same error3. The sfc /scannow command returns "Windows Resource Protection could not start the repair service"4. If I try tu remove the SP1 wuth command line wusa.exe /uninstall /kb:976932 I get Installer encountered an error: 0x8000ffff. Catastrophic failure5. I cannot repair from the boot DVD because it says I must restart in Windows and run from the DVD again and this get me another errorThanks a lot, Ariel
