I recently downloaded a trial of Windows Mechanic wasn't happy un-installed using its un-installer still there, re-installed tried advanced un-installer no joy not in programmes but on hard drive but can't get rid of. Thanks Joe.
If Sytem Restore fails try this to get rid of it completely Open search type the correct name of the program & delete anything that comes up, then go to Start/run/type regedit. Make sure My computer is highlighted click on edit click Find type in the exact name click find, delete any item highlighted with the related file name then click find next & do the same continue until there are no more. Do not touch anything else in the registry & make a backup of the registry before you start incase of any mistakes ( Highlight my computer click file click export
