    My CF-31 has lost it's Windows 10 Pro activation key authentication and the Diagnostic Policy Service will not start.

    It has Win 10 Pro installed on it (was installed by the seller when I bought the system) and until a few days ago everything was fine. Then one day it started showing 'shaded' messages about Windows being not activated, and the DPS was not able to be started. Also the Wi-Fi and Ethernet are both locked out.

    I tried entering the product key off the label on the underside of the system (it says it's for Win 7 which probably was the default factory version installed) and that didn't work.

    I can get the computer to link to the internet using my usb dongle based wireless broadband service, but the Wi-Fi and ethernet functions are still locked out.

    I've tried a handful of approaches to try and get the DPS to run but the same error code comes back, and I can't figure out how I'll re-activate Windows. Buying an official copy of Win 10 Pro is going to cost me something like A$400 !

    If I go to Windows Update in the System settings it says its missing update KB4551762 (2020-03 Cumulative Update for Windows 10 Version 1903 for x64-based System) but will not download it with the attempt to download it stopping at 1 percent.

    What options do I have? I've never had to deal with Windows activation issues in the past (with the older Toughbooks while all have Xp Pro on them).

    Craig.

    It seems the seller used one key for multiple pc's. Also it's very strange your win7pro key doesn't work for win10pro. As is the blocked internet access. In this case I would think there may be additional problems and I would prefer to reinstall win10pro with your win7pro key to be sure your OS is clean and safe. 1 hour task.

    Somewhere I do have a USB stick which I got from the seller with a copy of Win 10 Pro. I'm suspecting it's a malware or virus effect as I ran Clamwin and it picked up a bunch of things.

    Internet access not blocked - using it right now via my mobile broadband USB dongle. Wi-fi and ethernet are disabled and cannot be enabled because DPS will not run.

    I don't think I have a big enough USB stick spare to backup my files onto but what is the best way to save/backup/protect my files in order to re-install Windows from scratch?

    Download official Windows 10 installation tool

    The best way for backup in your case is to save (copy) only important files/documents etc, but not Windows settings. Of course it's better to copy them to an external media, but you can make a secondary partition and copy your docs there. Of course do not delete that partition during reinstall :D

    I tried to use the Windows 10 install tool from

    https://www.microsoft.com/en-au/software-download/windows10

    but when I ran it I got a very wierd error code with a note saying the tool cannot be run on this PC.

    The error code is 0x8008005 0x90018.

    So the easy way of doing an on-PC repair install with the Microsoft-supplied tool isn't going to work. :cool:

    I didn't know about that tool until I saw it in a Britec youtube video.

    Thanks I will have a good read. I now have located my USB stick with Win 10 pro, and also obtained a 256 gb USB stick to use for backing up my files and other data before I muck around with anything.

    Going into 'PC Settings' and attempting to get updates says:

    "There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x8007042c)"

    I've been able to use my USB mobile broadband dongle to use the Internet as both the wi-fi and the ethernet ports are disabled due to DPS not running.

    I've saved my files to a USB and tried to boot the system from the bootable Win 10 copy on a USB stick supplied by the seller when I bought my CF-31 a couple of years ago. It begins the process and I get given two options - the standard one doesn't work, and I don't feel comfortable trying the advanced one.

    Can someone direct me to a good comprehensive guide to booting Win 10 from a USB stick and using that to fully-reinstall Windows from scratch?

    At least the attempt to boot from the USB stick has not diddled the existing installation (otherwise I couldn't access the internet to post this), but I still have no usable ethernet or wi-fi because the DPS isn't running, and I can't get the system to install required Windows updates.

    Ta if you can offer some instructive help.

    PS. One option could be to get a new SSD, install that in place of the current one (so the system has a genuinely fresh C drive that's never had an OS installed) and try that out. It's a bit drastic and I really shouldn't need to, but it's an option I suppose. Current C drive is a Samsung ssd evo 850 500 gb according to it's hardware properties.
