Hi Ramesh back again.
Today I set the ProxyUser to 1, I then ran Procman to view the boot, I restarted the PC and once running I checked the ProxUser and it was still at 1, However, I noticed in the background iCloud booting up and as soon as this had happend I checked the PU and it had reverted to zero. I have put the latest Procman log into one drive, for some reason there was only one log this time so I do not know if I did something wrong but if so I don't know what. I now intend to stop iCloud running on the PC and see what happens then but I use iCloud for my phones etc. so I don't know what if anything you can suggest about this if it does turne out to be iCloud causing the problem. I will let you know the outcome shortly, Many thanks....
