Yes. Locks up about 1 minute after logging in to the new account.

Performing clean boot now. Thank you for staying with me on this. This one's a tough nut to crack!

 

[Brendan004]

Clean booted... locked up about 1 minute in.

 

[Sysnative Windows Update]

You disabled every service and Startup item?

 

[Brendan004]

I just went back in and disabled the startup items as well and we are up and not locking up! Ok. Now to find the culprit I presume?

 

[Sysnative Windows Update]

By process of elimination, disable them one by one and reboot until you find the culprit.

 

[Brendan004]

Enable I think you mean? Should I start with the services or the startup items?

 

[Sysnative Windows Update]

Yes, I meant enable. Startup items.

 

[Brendan004]

Ok. On it. Also, does this mean I can switch back to my old profile or do I need to migrate to this new one?

 

[Sysnative Windows Update]

Let's first determine the culprit and then we'll check the profiles.

 

[Brendan004]

Ok. There were 5 items in there. The 1st 4 items checked out to be good. The last one, iTunesHelper, immediately made the machine act screwy. The mouse got jumpy and I couldn't click on anything or type until about 90 seconds later and then it started acting somewhat normal. I disabled it again and the machine came up again clean.

 

[Sysnative Windows Update]

Monitor it for 24 hs and let me know.

 

[Brendan004]

OK. So it is still up and running, but with minimal services. I tried to reboot a bit ago with Normal Boot enabled but it locked up shortly thereafter. I presume there's more going on than just a screwy iTunes startup service. How would you like me to proceed?

 

[Sysnative Windows Update]

Enable Normal Boot, but disable iTunes.

 

[Brendan004]

Doing so now. I also just donated to your incredibly worthy cause.

 

[Brendan004]

Ok. System hangs on the Windows 10 icon in the middle of the screen with the circle dots about half way through.
