I bought my laptop that comes pre-install Windows 10 Home Single Language (activated).

However I wish to reinstall the my current Windows onto a upgraded SSD drive.

And I don't wish to lose my activation after reinstall.

Therefore I don't want to download any ISO file comes from outside sources

I wish I can create my own ISO from my current installed Windows OS.

Is there anyway I can do this?

Can I use the Backup and Restore (Windows7) comes from Control Panel to create this?

Will it lose my activation?

Can it reinstall onto different drive? (I remembered I did once before with a USB flash drive that only run UEFI menu to restore my Windows but without option to install onto different drive)

  • Try cloning your drive instead of reinstaliing Windows. – iTechieGamer Mar 3 '18 at 6:03
  • after clone would it auto show selection of 2 OS to boot during startup? – elliotching Mar 3 '18 at 6:50
  • No, it will boot from the drive you choose, not from the OS, because they're the same. – iTechieGamer Mar 3 '18 at 7:02
  • do I need to wipe my old drive? – elliotching Mar 3 '18 at 9:51
  • You don't need to wipe your old drive, but you can do it if you want to. – iTechieGamer Mar 3 '18 at 9:56

If your computer has UEFI BIOS then your licence key is installed on your BIOS, you only need to download the original Windows 10 ISO from Microsoft

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

Also many manufacturers allow download their OEM ISO from their support pages (i.e. Dell)

If you download and install the same ISO version that came pre-installed on your computer it will automatically reactivate with Microsoft, I have done it several times when i have to replace dead hard drives or reformat computers

  • because I'm still afraid it will not prompt for which drive to install since this is OEM customized installer compared to Original Windows ISO – elliotching Mar 3 '18 at 9:55
  • My laptop is Lenovo, and yes, I actually made one as USB flash drive – elliotching Mar 3 '18 at 9:55

    "If your computer has UEFI BIOS then your license key is installed on your BIOS" - Why does everyone say this? The Windows 10 key is NOT store in the BIOS. It's stored in the ACPI table. While related to one another there is a huge difference. – Ramhound Mar 3 '18 at 13:47

    "since this is OEM customized installer compared to Original Windows ISO" - No; No it isn't. Lenovo uses the standard Windows 10 Single Language ISO. – Ramhound Mar 3 '18 at 13:48
