There could be an issue with those things. You could try using a different USB stick to eliminate the stick, different USB port etc maybe try a disc instead of a USB stick if possible
You can disable it in the registry. H key local machine, software, policy, microsoft, windows, OneDrive, disable sync value change from 0 to 1 and it will turn it off. I may be a little off this was just from memory.
I completely agree and I would like to add one more thing. The way simple login responded to this issue was very nice. They could have been a whole lot more aggressive about this.
You're right, feels like stepping into an oven, as soon as you're in the sun you feel like you're starting to literally cook. It's awful, and in a city it doesn't cool much so you can't cool off. If heat doesn't get you the first day try the next when you're with down a little.
Thank you!
