Hello,
If the product was purchased at a normal price and from an authorized retailer, slight variations in the hologram on the USB installation media can occur. The holographic effect on USB sticks is often less pronounced than on COA labels or the new authentication label, so it may not show the same strong color‑shifting effect as shown on Microsoft’s webpage.
However, if you are unsure, the most reliable approach is to send a photo of the hologram to the retailer where you purchased the product and ask them to confirm that it is genuine. Authorized sellers can verify this directly with their distributor.
