Finally resolved a registry problem on the PC that was trying to launch two different versions of the same program at startup. ( Bit torrent) Happened after the OS decided to trash my original profile and then make a new one.
Had to trawl through with regedit and find the keys that were the launch items, identify the versions that they related to and then delete the old ones. Found quite a few dead ones as well in the process so got rid of those too. I think there's a duplicate launch key but it doesn't seem to cause any issues.
Always a little cautious when modifying the registry and backup beforehand but a good result.
