I hit this error while trying to delete a leftover McAfee Validation Trust Protection Service using sc delete "mfevtp" command.
This is how I resolved the issue:
- Open Registry Editor (regedit.exe)
- Navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\mfevtp
mfevtp is the KeyName of the service you having problem with (the same you use with sc delete command) - Delete sub-key called "Security"
Allways make a registry backup befory deleting any keys - Restart computer
After reboot sc delete "mfevtp" completed without any errors and service was gone for good.
Windows XP
