Here is the result of my research into this problem as I solved it by reading people's comments on this and other forums.
I updated all 3 of our family laptops to windows 10 and within a few weeks they had all developed this problem. I was therefore in a position to compare what software was on each laptop and try various things.
Symptoms: The Group policy client message was not the only symptom. After this message showed, it was impossible to access the "Update and security" part of the "settings" menu. Also, the policy client message only occurred on startup following a shutdown which was halted by a message saying that a "taskhost" windows was still running an "automatic app update". This was the same on all 3 laptops.
So this error seems linked to the update process not the content of the update itself. The first thing you need to do is get your pc temporarily working properly again. I tried various things but a you-tube video led be to this process which worked every time:
- open a command prompt window as an administrator (right click on the app in the start menu)
- type "netsh" and press enter
- type "winsock reset" and press enter
- restart your computer
At least for me this got rid of the message and made the update menu start working again. I've no idea what this resets but it works and appears to do no harm. HOWEVER, this is only a temporary fix and your issue will come back in a few days!
I read somewhere else that this problem is caused by apps that are installed with "admin" rights trying to update themselves. Chrome is mentioned in particular. I uninstalled chrome and tried to stop other apps from auto-updating. I also suspected MS Office 2007 as this was one of the few apps on all 3 laptops. So I stopped "update" from updating "other window products" under advanced options. I noticed under update history that an update for MS Office 2007 kept failing, so I manually installed that update.
Some of this seemed to make the problem take longer to come back, but it always did at different times on all 3 laptops. I suspect that I didn't manage to stop all apps doing this.
Then a post about the "taskhost" process stopping shutdown led my to the solution. Windows 10 has a special "fast startup option". Basically this seems to make your PC take longer to shutdown but makes the startup a bit quicker. Turn this off! That's it! You find it by:
- Power and sleep
- additional power settings
- click on "choose what the power buttons do"
- scroll down to Shutdown settings
- uncheck the box next to "turn on fast startup"
- click save changes
This worked for all 3 PCs.
My view is that this problem happens when certain apps are trying to update themselves when you turn off your pc. Something conflicts with how the windows "fast startup" process shuts down your pc. This corrupts something about the user accounts and windows update program. But this only happens for certain hardware/software combinations so only a few people get this error.
Hope this helps other frustrated users out there!
Thank you !!! I have joined this forum !!! ... Your temporary fix worked for me ... I will wait to see id the problem persists to do your permanent fix
