[Hardware] Fujitsu Esprimo Q958 will not power down with USB device connected

A couple of months ago, around August-September I believe, we got a new model of Fujitsu Mini-PCs – the Esprimo Q958. We had already been using the Q957 without any troubles for a while so we did not expect to face any problems with this new iteration either. Besides a newer CPU generation (Core i5 8^th Gen compared to Core i5 7^th Gen) nothing had really changed, we thought.

But soon after deploying a number of those new Fujitsu Esprimo Q958 machines to our users we got weird reports of machines not fully powering down when shutting down Windows.

The machines would simply stay powered on when you pressed the “Shut down” button in Windows. The machines would keep running, with power management disabled, and thus the CPU would soon get warmer and warmer, making the fan turn on to 100%, which in turn resulted in a lot of noise thanks to the very small fan.

[BUG] Windows 10 default user profile oddity - Free folders for everyone

Remember my post from July 2017 about how the default user profile under Windows 10 was writeable by any user (no admin rights required) if you had 1607 installed at any point in time?

 

Well, here we are again with a new oddity.

 

[BUG] Windows 10 default user profile is potentially writable by everyone

This is the story how I found out (by proxy) that the default user profile in Windows 10 is potentially writable by any user and the odyssey of trying to get this security bug fixed ... and failing to do so in the end.

For those who do not want to read the full story I posted a TL;DR version at the bottom. ;)


2017-05-19 19:55 - I got contacted by a friend who asked me for my input on an issue he (or rather his company) was having for weeks and months already and had not been able to figure out yet. Even Microsoft Germany, who they contacted themselves about this issue on 2017-03-28, did not have a solution for them.

Some background: His company is selling servers and support for them. So far, there are over 1.800 of their servers with over 100.000 connected clients and over 1.000.000 users out there and they had a problem with newly deployed Windows 10 systems they were not able to figure out.
