Dell precision 7710 My problem is: I changed the device's original system, Windows, to Linux... Lost OEM activation key

Hi

Try

Linux
sudo strings /sys/firmware/acpi/tables/MSDM | tail -1

CMD
wmic path softwarelicensingservice get OA3xOriginalProductKey

POWERSHELL
powershell "(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey"

@ann_droid​ It turns out that copying Windows when installing them the first time you enter the C:/Windows/System32 and delete some data there or isolate it and consider them viruses such as (sppsvc) The file for activating the OEM that came from the factory with the device، Even if you exclude the file, it does it against my will, delete and isolate this file and others, and the Windows Defander notifications increases so strongly that it makes the device very hot Fevoz Defander becomes the virus I have...The problem was sampled by re -burning and installing Windows from the bot by installing Windows without the internet and skipping writing the activation key and when I entered I installed ESET quickly without operating the internet and after I turned off Windows's anti from the "regedit"

ESET is the place of Windows's anti -Windows, and I no longer suffer from it, but I had to pay to struggle and this is annoying. 

Today I entered the support community again because I suffered from a new problem: 

I used to use Windows normally. I updated some optional updates from Windows updates and changed some NVIDIA Control Panal and I was downloading a game and watching a movie at the same time, but suddenly the device turned off 

And when you press the power button to run the device, the button light works only with the battery and operating lights only 

Battery lighting lights up as follows: 2 Orange 1 White Light Blinking, knowing that the screen is black and did not work permanently

I raised it, changed the place of the hard and the additional Ram 16 GB, did not work, then I returned them to their place, and nothing changed.

The first thing I tried or separated the battery, charging the device and operating it on the charger 240 W head but did not work, I tried the battery removal and separated the charger and pressed the operation button for 20 seconds and 30 seconds to devote himself from the shipments, but nothing.... happened
