It's called a Volume Licensing Key.
Or possibly System Builder.
But if you're passing this OS on to your customers, there is no 'cheap'. Just pass on the actual license price on to your customers.
They will get a legit OS, and you'll have far less problems in the future.
So your saying there is no way to do it ?
Alri thanks dude, also I was wondering could I maybe download Windows 10 form microsoft for free and then put that on their pc?
No, there isn't.
If you are repairing a customers PC, either you use their existing license key, or you sell them a new as part of the process. If it costs you $90 for the license, you charge them $90. Your labor is not included in that, and may be a different line item on the bill.
But no, there is no 'cheap' batch of valid licenses, unless you go through Microsoft. And unless you are a large organization, each license will cost you the same as it does me for a single license.
Maybe, possibly, if you go through some other valid reseller...CDW for instance, you could buy in bulk for a bit cheaper.
But if your are passing this install off to your customers, you
must pass them a valid, legal OS, that you are authorized to sell to them.
You don't want to get sued for 'selling' a bogus license, do you?
