To Remove Entries in the Msconfig startup tab
These values are stored in the Registry. Go to Start/Run/Regedit to access
these keys and values to delete/remove them:
For items that were in the Start menu, Programs, Startup folder:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\MSConfig\startupfolder.
You'll find a subkey for each disabled item.
For items loaded from the Registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Shared Tools\MSConfig\startupreg.
Again, you'll find a subkey for each disabled item.
