Windows 8.1 activation problem in my laptop

[sam781]

I can't upgrade from windows 8.1 to windows 10 using the windows 10 Bootable pendrive. .

you have to setup.exe from within your current OS to upgrade
Do not boot from media to perform upgrade

how did you install it?
If you booted from the windows 10 setup media and did a clean install - windows 10 will not activate..
You must run the setup.exe from within windows 8.1 to perform an upgrade installation - and activate..
Then once your PC has had the activation recorded - you can then clean install windows 10

You MUST upgrade first to get the activation recorded

Thanks... It worked fine.
