Hi, I have an old laptop that came with a windows 7 coa sticker. I want to use this key in my next build, but I can't turn the laptop on to deactivate. Please help.
Laptops are almost always OEM license and limited to that specific PC.
And Win 7 is now dead so Microsoft isn't likely to help you transfer the license even if it was a full version.
ok. where is it a legit and cheap way to get an older licesnce to use with my new machine?
Not unless you have an older Win 10 key laying around.
8/8.1 compatibility isn't assured on the new generations leaving 10 as the only option now.
