I would like to install the old HDD of my old laptop in my new gaming PC because I need more memory. My question is what happens when I install the old hdd and build as a memory extension in the other PC because on the HDD synonymous windows 10 on it.
Just try it.
Probably the computer will start up normally and some drivers will not be right.
In the best case, they are automatically recharged, otherwise you have to install the drivers manually.
As for the activation of Windows 10, that could be gone.
But more can't happen there.
If you do not previously unlock the activation of the Windows on the old PC and you do not read the serial number, you get on the new computer a non-activatable Windows and you müsstesrt buy a new key
But is it possible that I already delete the hdd on the laptop and then install it in the PC?
Of course that is possible, but then reinstall everything on the "new" computer
Ah, misread…
You have a Windows on the other "new" calculator.
Of course, you can flatten the old HDD and use as additional memory.
Sorry, read
