Windows 10: Windows license copy from laptop to PC

Hello! I have a laptop with Win 11 installed on it and thinking to buy a PC. Do I need to purchase with preinstalled Windows or can I install it myself since I do have a copy on the laptop?

Windows 7 license question

Hi. Is it possible to take a Windows 7 Pro license that's currently installed on a Dell laptop and move that to a Dell desktop and take the Windows 7 Home license from the Dell desktop and install that on the laptop? I would just be switching the licenses from one to another. I get conflicting answers. The desktop would have a new hard drive installed on it and more RAM. I would be doing a fresh install on BOTH machines using a legitimate bloat free Windows disk. Thanks!

 

Selling PC with Windows license

I'm sure this has been asked before, but I want to sell a PC to my brother and I want the Windows license to go with it. I have all the parts for a replacement PC that I will build in a few days and for that I will buy a new Windows license. I guess the
questions I have are:

1. How do I transfer a Windows license to another person, or is that possible with current licensing rules? The hardware that the license runs on would be the same, just a different person. I don't know if he has a Microsoft account, but we can set one up
   if necessary. This license was originally bought as Windows 7 and then converted to a Windows 10 license. I don't remember if it was an OEM or retail copy or if that is important.
2. Since I'm building another PC which will need a Windows license, would it just be easier to transfer the license I currently own to the new PC and buy a new license for my brother? In that case, the license would stay with the same person (me) and the same
   Microsoft account, but will run on all new hardware.
