Hello, people I need to transfer my windows 8.1 oem copy to my new pc, you can do it only if you unistall windows fully from your older pc, because you can use your license only on one PC at the time. I tried refreshing windows, but it didin't work, how should I unistall windows from my Acer laptop, so I could use it on my new pc? Or basically how to remove windows 8.1 without reinstalling?
