Counterfeit Windows Licenses

Did some business with a person in China (with free delivery via DHL), advertising cheap Windows 7 OEM/Retail and other software- ordered a few samples.

Unfortunately I will not show to what extent they go to to actually counterfeit the software but trust me- it had me fooled until this happened.

This only happened once I peeled it off the OEM case (which after closer inspection has a square with DVD written in it) Original Windows cases don't have this.

I installed this on a Virtual Machine.
Activated it and passes Microsoft Genuine.
