Microsoft Policy States:
“Large brand-name computer manufacturers, such as Dell and Compaq, often include OEM software on non-holographic “recovery” or “reinstallation” discs that show the manufacturer’s brand name. These software packages are typically marked with a phrase that states, for instance, “For Distribution with a new Dell PC only.” Recovery or reinstallation software is licensed only for distribution with new computers and can be redistributed only with the computer for which it was initially distributed. Distributing such software with individual PC hardware components (e.g. hard drive; RAM) does not comply with Microsoft’s OEM distribution requirements.”
This sale includes the Original Recovery Media and CoA sticker for Windows 11, the original broken not economical repair computer and motherboard. They are only available for pickup (contact us before purchase to arrange a pick up) – additional fee of €180 will apply. If not picked up in 3 days after the sale, it will be disposed of. Otherwise, you will receive only the Activation key for Windows 11.
OEM Software:
Microsoft’s Distribution Agreement for System Builders states that the system builder software packs are not intended for distribution to end users unless the end users are acting as system builders by assembling their own PCs. A “system builder” is anyone who assembles, reassembles or installs software on a new or used computer system.
