Hi, i'm maybe going to buy a new pc, but its without a operating system. It's expensive, so i'm thinking of downloading windows 10 on usb and buy a product key from Ebay. If the Product key gets blacklisted will my pc stop working? or will it say that windows isnt activated?. If the key works will my windows work normaly?
Buying licensed software, OS or otherwise, from ebay is almost always a bad idea.
How many other people did he sell this same license key to?
It may work for a few weeks/months, until it used on a system on the other side of the planet.
Or until that corporate license key wants to validate itself from the company license server.
You're buying/building a whole new PC.
A valid license key is,
at most, 10% of the PC price.
Either just install Win 10 and leave it Unactivated (yes, it runs like this).
Or buy a
valid license key from a known retailer.
Don't patronize these ebay clowns.
