I am looking for help from anyone with intimate knowledge of the group policies.
I have switched off all the power management settings which allow the O/S to switch off a device to save power. I am still getting disconnects and some times this affects the mouse and keyboard such that my only resolution is to switch the whole machine off and reboot, sometimes losing current information.

I have two identical machines one running Win 10 and one Win 7.
Comparing the power management in both shows that Win 10 allows more devices to be switched off than Win 7. I am now very fearful of switching both my machines to Win 10 in case this problem causes me to lose important information.

Is there a group policy? that affects all devices.

I can understand MS including this for tablets, mobiles and laptops but it should not happen in PCs.
