How to reinstall Windows after Linux

[Ekrar]

Hello

I had my Laptop with preintalled windows. Recently I have installed and tried different versions of Linux. Now I want to get back to Windows. How do I reinstall Windows as I donot have the product key and from where do i download Windows from.

A little help would be most generous. Thank you.

Hi

A tad tricky,

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

If in doubt please ask.

Hi

Also the Boot Area of the BIOS may have a Boot Manager list and it can sometimes be re-arranged...

Move the Windows Boot Manager to the top.

I have several bootable Linux OS's and W10 currently installed.
