The first Windows 11 OS update for 2026 is now rolling out with important fixes — including one that impacts battery life on PCs with an NPU

Windows Update.

2026 is officially off to the races as Microsoft's first Patch Tuesday for the year introduces new fixes and improvements on Windows 11. Update KB5074109 is now available via Windows Update for users on Windows 11 version 24H2 and 25H2, and includes some important fixes.

The first notable fix is one related PCs with an NPU. Turns out, there was an issue where some NPUs would remain powered on when the system was idle, which resulted in reduced battery life. That issue is now fixed as of this week's updates, which should mean better battery life on these PCs.
