Charge HP Stream 7 while using it with an OTG cable

After a quite frustrating experience with an HP Stream 7 tablet, which refused to get charged while having a USB stick connected to it via an OTG cable, I found an extremly easy solution:

Just disable the Microsoft AC Power Supply which can be found in the device manager under Batteries.

Voila – that’s it.

I have the German version only where it says Microsoft Ladeger├Ąt and can be found under Akkus.
