What You Need to Know About MAR Stickers on Windows 10 Pro Devices

When it comes to purchasing a refurbished Windows 10 Pro device, you may have come across a sticker that says 'MAR' or 'Microsoft Authorized Refurbisher'. But what does this mean and how does it affect your installation and activation process? In this article, we'll break down the importance of MAR stickers on Windows 10 Pro devices.

The MAR sticker is usually affixed to the device alongside the original COA/Product Key sticker. However, it's essential to understand that the MAR scheme is a separate program that provides a new Product Key for activation purposes. This means that the original Product Key used to activate the original Windows installation becomes void and cannot be used again.

The MAR scheme requires documentation from the MAR company, which must include their contact details, recovery method (media or recovery partition), and a MAR sticker with a new code to activate Windows 10 Pro. In some cases, you may need to provide your Win 8 product key embedded in the BIOS/UEFI firmware to prompt the MAR.

It's crucial to note that the MAR scheme is supported by the MAR company, not Microsoft. This means that if you encounter any issues with activation or installation, it's best to contact the MAR company directly for assistance.

In the UK, the MAR sticker typically includes the name of the MAR company. The original Product Key used to activate the original Windows installation becomes void and cannot be used again, hence the provision of a new 25-character Product Key.

To comply with the scheme, the MAR sticker must be affixed to the device in addition to the original COA/Product Key sticker (not as a replacement or stuck on top of the original).

In summary, when purchasing a refurbished Windows 10 Pro device with an MAR sticker, it's essential to understand that you'll need to use the new Product Key provided by the MAR company for activation purposes. The original Product Key becomes void and cannot be used again.

If you're unsure about your MAR sticker or have any questions regarding installation and activation, we recommend contacting the MAR company directly for assistance.
