    To protect against counterfeiting of Microsoft software, the following measures should be observed before purchasing and during licensing:

    Microsoft Certificate of Authenticity

    The Certificate of Authenticity is placed in the form of a sticker or label on the boxes of Windows, Office and Windows Server software. On the Certificate of Authenticity you can find the product name. In addition, the certificate has the following copy protection features:

    • Integrated Security thread:  Ein Silber schimmernder Faden ist in das Papier eingewoben (ähnlich wie bei einem Geldschein) und in Teilen sichtbar.
    • Tilt color: If you tilt the certificate, the color changes from green to a red/magenta depending on the viewing angle

    Microsoft data carrier (CD/DVD) with hologram

    Windows and Office are shipped on CDs or DVDs that have a hologram built into them. If you hold the disc against a light source and then move it, you will see the product name and other lettering on the CD, shown in bright colors and with 3D effects.
    The hologram is integrated into the data carrier. So it is not a sticker that you can peel off. If this is the case, then it is a counterfeit.
