Uh oh! Not all Arm PCs are getting Windows 11 26H1 special update | usagoldmines.com

Microsoft surprised the Windows community with its somewhat-recently announced Windows 11 26H1 update, which won’t be available on all Windows PCs. Now, the company is revealing important details about this Windows update, namely which PCs will be getting it.

What we’ve known up to this point is that only certain Arm computers will receive Windows 11 26H1. The majority of Windows 11 users, who are running on Intel or AMD processors, will therefore not receive this Windows update. As Microsoft said previously: “Windows 11, version 26H1 is not intended as a feature update for existing devices and will not be offered through Windows Update.”

Unlike most big updates for the operating system, Windows 11 26H1 doesn’t bring any new features but only makes changes under the hood. However, according to Microsoft, “Windows 11, version 26H1 is a hardware-optimized release […] with capabilities tailored specifically for those platforms.” It’s unclear what that means yet.

That said, Microsoft has been rolling out Windows 11 26H1 to compatible Arm PCs since February 10th, 2026 and plans to support this version until March 4th, 2028 on Windows 11 Home and Pro (while Enterprise and Education editions will be supported until March 13th, 2029).

The new bit of information we now have is that only the following PCs with these three processors will receive Windows 11 26H1:

• Snapdragon X2 Plus (“X2P”)
• Snapdragon X2 Elite (“X2E”)
• Snapdragon X2 Elite Extreme (“X2E”)

This information was quietly put forth on this support page. This means the first generation of Arm-based Copilot+ PCs with Snapdragon CPUs won’t be able to take advantage of Windows 11 26H1.
