The Microsoft Authorized Refurbisher (MAR) Donation Program grew out of Microsoft's growing awareness of the importance of computer refurbishing and reuse in nonprofits and schools as well as for people on the wrong side of the digital divide. Through the program, Microsoft provides donated Windows 98 and Windows 2000 operating systems to nonprofit PC refurbishers. MAR was created to fulfill the needs of refurbishers, nonprofits and schools to equip donated computers with affordable operating systems. MAR works with U.S.-based nonprofit computer refurbishers that recycle donated PCs for nonprofits, public libraries, and K-14 schools. The CACRC is licensed under the MAR agreement.
