I recently tried to run sf/scannow and got the following message "Windows Resource Protection could not start the repair service
I am using Windows 7 but following an article in one of the 'compuer tips' mags
had added a program which loads the Vista Start Menu instead of Windows 7 start menu (the Menu is much nicer than the standard Windows 7 Start Menu).
I found that trying to run sf/scannow through the 'Vista' start menu (accessories....) did not work.
Once I switched off the 'Vista' start menu and ran sf/scannow from the regular start menu for Windows 7 - it started straight away no problems.
Just an observation - I guess this was a compatibility issue or something - I haven't had any other problems with the 'Vista' start menu in Windows 7 but I now have a 'heads-up' (if I decide to keep the Vista start Menu) for one of the places to look if something else won't work properly.
