Most Recent Windows Updates
Here is a running timeline of the latest Windows 11 updates, most recent first.
KB5129195, September 14, 2026 (Emergency update)
An out-of-band update released to fix Remote Desktop Services (RDS) instability that came from that month’s Patch Tuesday release, along with a security fix for a privilege escalation flaw. This was not a scheduled release, Microsoft pushed it out early because the RDS issue was serious enough to not wait for the next monthly cycle.
KB5124008, September 8, 2026 (Patch Tuesday)
The regular September monthly update. It patched two actively exploited security vulnerabilities and included a large batch of quality fixes, though it also introduced the RDS issue that KB5129195 had to fix six days later.
KB5121003, August 11, 2026 (Patch Tuesday)
August’s monthly update. It added useful features like expanded Windows Hello support and new touchpad gestures, but has also been linked to BIOS corruption issues on some HP laptops and charging problems on some Lenovo laptops that are still being worked out.
KB5121768, July 2026 (Emergency update)
An emergency out-of-band hotfix released just days after that month’s Patch Tuesday update caused problems specifically on Dell hardware.
KB5101650, July 2026 (Patch Tuesday)
July’s monthly update, notable for shipping one of the largest batches of fixes of the year.
How Often Does Microsoft Release Windows Updates
Microsoft follows a regular monthly schedule known as Patch Tuesday, which falls on the second Tuesday of every month. These updates bring routine security patches and quality fixes.
Outside of that schedule, Microsoft sometimes releases out-of-band (OOB) updates. These are emergency fixes pushed out early, usually because a recent update caused a serious problem, or because a security threat needs to be patched immediately rather than waiting for the next monthly cycle.
How to Check If You Have the Latest Update
- Go to Settings
- Click Windows Update
- Click Check for updates
- If anything is available, it will download and prompt you to restart
To see exactly which update and build you currently have installed, go to Settings > System > About and check the OS Build number.
How to Make Sure You Don’t Miss Important Updates
- Turn on automatic updates through Settings > Windows Update > Advanced options, so security fixes install without you needing to check manually
- If you are currently on Windows 11, version 24H2 Home or Pro, note that support ends October 13, 2026. Our Windows 11 versions guide explains what that means and how to move to 25H2
- If you are still on Windows 10, upgrading is free for most PCs. Our step-by-step upgrade guide covers exactly how
