[bora.glryz]

I had an old laptop which is broken now(long story).I want to build a new PC.
My laptop's ssd and hdd are removeable.Can I use them for my new build? It had windows 10 (activated) installed on the ssd. When I build the pc and plug the ssd,will I be able to use windows 10 (activated)?

And the games too.what will happen to my steam,uplay and origin games? Will I be able to play them? Or will I need to download them again?

The physical drives, sure.
The OS on it? Won't work in a new PC. Almost certainly won't even boot up.

Without watching the whole 20 minute thing, this relies on Sysprep?
Which requires the original system to be running, to 'prep' the drive and OS.

While that can work sometimes, for most uses a clean install on the new hardware is just as easy.
