HP Stream up windows 10 update started problems

[FitzG]

Around November 2018 initiated the latest OS update. Since then the Tablet has become almost useless. Extremely slow to startup and run. Many applications don't work. No internet connection although seems to indicated all devices are working correctly. Unfortunately it was not set up to save restore points. Trying to reset the thing back to original (volume buttom and start button together for at least 3 secs brings up the menu but can't find anything that will help the problem. (This Tablet seems to have constant problems since I made the mistake of upgrading from Windows 8.1 to 10.) Should I download all drivers onto a USB using another computer and try to reinstall them all. Ideally I'd like to go back to Windows 8.1 but can't find a way to do this. Thanks!

Hi

I would check and record any keys for activation etc that you can.

Backup all DATA prepare a Repair DVD/USB from here(s)

If the F11 is still available, and that was W8.x, then a Factory Fresh install should go back to the day you first got it.

NB: How to avoid future updates/upgrades is a contentious issue I believe.

If in doubt please ask.

Doing research, and none of the methods are mine, I have some, simple single lines of code that will list the same value for your Windows 10 Product Key…
Two for Windows 10 and one for Linux.

W10 Using cmd.exe as an Administrator (copy and paste accordingly).

wmic path softwarelicensingservice get OA3xOriginalProductKey >> c:\ProdKey.txt

Creates a text file called ProdKey.txt on your C:\ area.

Next is a PowerShell command, as Administrator...
(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey

but it will run within W10 using cmd.exe as an Administrator.
powershell (Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey

Last, but not least....
Linux@Lubuntu:~$ sudo cat /sys/firmware/acpi/tables/MSDM | strings | tail -n 1
