Over a 24 hr period random programs open by themselves, eg adobe photo shop, or Office Word; never the same program consecutively and not in any pattern. I have checked system logs to see if there are any causes to the problem but cannot find anything out of the ordinary. This has been happening since day 1 of setting the PC up. This PC is also stand alone and not connected to the Internet, so Windows Updates were disabled straight away.
Also after the program that has auto opened is closed, it is noticed that the icons on the desktop have moved to different locations. Auto Arrange is turned off, and Align To Grid is turned on. The icons change places each time as well, never in the same place twice.
The only programs installed on the PC are Adobe, Office accounting and printing software's. The PC is occasionally turned off, usually left in Sleep mode over night. but even when turned off the icons move.
The PC in Windows 7 HP 64bit running SP1.
