Having the same problem, I followed the above link.
I needed to go to the 2nd stage and use regedit.exe. as the regsvr32.... file could not be found.
The settings under HKEY_CURRENT_USER.....User Shell folder for Programs and Start menu were correct.
The settings under HKEY_LOCAL_MACHINE....User Shell folder were all missing except for the 1st line which said default.
i do not understand how to reinstate the default values for the 7 folders listed in the article including Common Start Menu and Common programs which relate to this specific problem.
I assume I should have all 7 entries.
Can you please provide an "idiots guide" to correcting this.
