Microsoft has started rolling out the August 2026 Patch Tuesday update for Windows 11, and after going through the full changelog and testing everything, I feel there is no headline feature this time. It is a quality-of-life update with dozens of small fixes and refinements.
The update ships as Windows 11 KB5121003 (OS build 26200.9165 and 26100.9165)Â for Windows 11 version 25H2 and 24H2, and takes everything from the July 28 optional preview, KB5101684, and adds it into the mandatory August security release.

Voice Access gets its biggest upgrade in a while, File Explorer finally shows file sizes properly, Windows Hello adds support for external fingerprint readers, and there is a long list of smaller reliability work across the taskbar, Start menu, networking, and power settings.
Like every recent release, and I feel like a broken record here, this update also arrives in two phases. A gradual rollout hands features to devices over time through Microsoft’s Controlled Feature Rollout system, so some of what is listed below may take extra days to show up after you install. A normal rollout goes to every eligible device at once and covers the security-critical pieces, including Secure Boot.
Speaking of which, Microsoft confirms that Secure Boot certificates from 2011 keep expiring in stages through 2026, and that PCs still waiting on the newer 2023 certificates will keep booting and updating normally in the meantime. If you have not checked your Secure Boot status recently, it is worth a look.

Windows 11 version 24H2 Home and Pro reach end of updates on October 13, 2026, with Enterprise and Education supported until October 2027. 24H2 is already on the list of 15 products Microsoft is retiring in 2026, and Microsoft is force-installing 25H2 on eligible Home devices to keep them up-to-date.
What’s new in the Windows 11 August 2026 Patch Tuesday update
Here is a quick list of everything coming to your PC with the mandatory August update:
- Voice Access adds Voice Isolation, Korean language support, and more reliable startup.
- File Explorer shows file sizes in KB, MB, or GB instead of everything in KB.
- Middle-click now opens a folder in a new tab from the address bar and Home page.
- Windows Hello Enhanced Sign-in Security works with external, plug-in fingerprint readers.
- Touchpad gestures add adjustable scroll and zoom speed, plus accelerated scrolling.
- Taskbar notification badges switch from red to your Windows accent color.
- You can now remove the Image Generation AI component from supported Copilot+ PCs.
- Windows Search gets better at handling typos and partial app names.
- Power and battery settings apply more consistently across sleep, hibernate, and lid-close.
- Secure Boot certificate rollout keeps expanding to more eligible devices.
Voice Access gets its biggest upgrade in a while with Voice Isolation
The only “big” new change this month is on Voice Access, and it is part of Microsoft’s focus on voice as a priority area for 2026. Voice Access now has three speech recognition modes under Voice Access settings > Improve speech recognition:
- Voice Isolation filters out other speakers and background noise, though it needs a one-time voice setup first by going to Voice Access settings > Improve speech recognition and selecting Voice Isolation.

- Remove background noise only cuts out non-speech sounds like typing or a door closing, with no setup required.
- No filtering keeps the default microphone input untouched.
I tried Voice Isolation with a podcast playing in the background, and the difference over the default mode was noticeable. Voice Access didn’t pick up any unwanted words from the audio, which had been a real problem before this update.
Voice Access also adds Korean language support, and Microsoft also improved the reliability of starting Voice Access. Interestingly, Windows chief Pavan Davuluri wrote in his July update on Windows quality that voice was one of the areas the team has been focused on since March.
File Explorer finally shows file sizes in the right units
File Explorer’s Details view has shown every file size in kilobytes for years, regardless of whether the file was 10KB or 10GB, and all of us have gotten used to it by now.
Anyway, with the August Patch Tuesday update, file sizes display using appropriate units, KB, MB, or GB, based on the size of the file, so a 10MB file no longer shows as 10,000KB.

I have always found this oddly frustrating given how basic a fix it is, since converting kilobytes to gigabytes in your head while browsing a drive is not something we want to waste our brain tokens on!
The feature is rolling out gradually, so it may not be immediately visible.
Address bar navigation is also improved. Middle-click now opens a folder in a new tab from both the address bar and the File Explorer Home page, matching how tabbed browsing works elsewhere in Windows.
Microsoft also fixed a grey flash on load and unexpected scrolling to the top of the Home page in certain cases, and file thumbnails in the Recommended section are now crisper.
Windows Search gets better at handling typos for apps
The August update brings forward Search improvements Microsoft has been testing for months. App search now better handles typos, dropped letters, extra characters, and partial names, so a misspelled app name is more likely to show the app you meant to search for.

Searching Windows Settings also improves here, meaning more useful settings should appear higher in the results list.
We first saw the typo-tolerant search behavior in an Insider Experimental build back in June, where searching “pwerp” correctly returned PowerPoint. It is good to see that work reach all PCs now.

Windows Hello Enhanced Sign-in Security now works with external fingerprint readers
Windows Hello Enhanced Sign-in Security, or ESS, previously required a built-in fingerprint sensor. The August update extends ESS to peripheral fingerprint sensors, so desktops and other Windows 11 PCs without a built-in reader, including Copilot+ PCs, can use this more secure sign-in method too.
To set it up, plug in a supported ESS fingerprint reader, go to Settings > Accounts> Sign in options, and follow the enrollment prompts.

Microsoft first disclosed this feature back in January 2026 through KB5074105, and it is only now beginning to roll out to all PCs.
Touchpad gestures add adjustable scroll speed and accelerated scrolling
New gesture controls for precision touchpads come under Settings > Bluetooth & devices > Touchpad. You can adjust the baseline speed for scroll and zoom gestures, and there is a new accelerated scrolling option that speeds up scrolling the more you repeat the gesture, so long documents move faster the longer you keep scrolling.

I did not expect to care about this one, but after using accelerated scrolling on a lengthy PDF I had downloaded, it turned out to be one of the more surprisingly useful small additions in this update. It is the kind of change you only appreciate once you have used it.
You can now remove the Image Generation AI component from Copilot+ PCs
Supported Copilot+ PCs can now uninstall the Image Generation AI component where it is installed, giving users who do not use the feature a way to reclaim the space it takes up. Microsoft has slowly made AI components optional after pushback over disk space and unwanted defaults.
Widgets and Start menu pick up smaller refinements
Taskbar notification badges switch from red to match your Windows accent color, which is a smaller version of the badge changes Microsoft already rolled out for Insiders earlier this year when they turned off the MSN feed and ads in Widgets by default.

New users also see a simpler Lock screen, with Weather as the only widget shown by default instead of a cluttered set of cards.
Start menu view preferences are now retained more reliably, so your chosen layout won’t get reset spontaneously. Keyboard navigation also improves when focus is set to the apps list within the Start menu.

Also, the Start menu’s account control flyout gets a design refresh and now shows a badge for your subscription status, which you can view by selecting your account picture in the lower-left corner. It is limited to users signed in with a Microsoft account, and availability varies by device and market.
Accessibility, input, and windowing improvements
Magnifier on touch-enabled devices gets a fix for the horizontal and vertical touch bars used to pan the magnified view. These are now off by default so they no longer obstruct magnified content, though you can turn them back on in Settings > Accessibility > Magnifier if you use touch panning.

Fluid dictation for Voice Typing is now off by default for new users, with a teaching tip shown the first time the feature is used. Mouse cursor size now persists more reliably between sessions, and system dialogs open at the appropriate size on small tablets.
Power, Windows Update, and networking reliability improvements
With the latest Windows 11 update, Power and battery settings apply more consistently now. Changes you make in Settings, covering display, sleep, hibernate, the power button, the sleep button, and lid-close behavior, now apply across all power plans instead of just the active one.
Microsoft also restored the ability to set a threshold for when Energy Saver turns on, under Settings > System > Power & Battery.

Windows Update gets two minor fixes. Update progress calculation in Windows Update Settings is more accurate now, and update clean-up logic has changed to improve system performance right after an update finishes installing.
On networking, DHCP renewal reliability improves in a few scenarios, particularly when a device receives a NACK from the DHCP server, and on devices using Modern Standby.
Print performance also improves for IPPS printers, so pages should print faster on secure Internet Printing Protocol connections.
Clipboard reliability improves in some Remote Desktop and Azure Virtual Desktop scenarios too.
General reliability improvements across explorer.exe and sign-in
Microsoft continues chasing explorer.exe stability. The August update improves reliability when opening Jump Lists and recent files, when sharing files and folders, and when using Task View and multiple desktops. It also improves the reliability of the Windows sign-in and lock screens, especially when system memory is low, and improves Start menu and taskbar reliability during startup.

System sounds are more consistent when using Windows in dark mode, and you wonder how sounds and dark mode are even related!.
Time zone change detection is more accurate, and daylight saving time data has been corrected for Middle East Standard Time in Beirut, Morocco Standard Time in Casablanca, Israel Standard Time in Jerusalem, and Greenland Standard Time in Nuuk.
Fonts get attention too, with restored support for Unicode variation sequences in the Myanmar Text font and improved character shaping for the Mongolian Baiti font. The taskbar’s system tray area also loads more reliably on touch devices used in tablet mode.
And an important feature for parents, Windows Setup now shows a parental controls notice highlighting available family safety features during setup.
Secure Boot certificate rollout continues in the normal phase
Unlike most of the changes above, Secure Boot updates ship in the normal rollout phase, so it applies as soon as you install the update. The release adds more high-confidence device targeting data, expanding the pool of devices eligible to automatically receive the 2023 Secure Boot certificates. Certificate deployment through Windows Update keeps continuing across supported PCs and non-managed business devices over the coming months.

Microsoft has been clear that devices still waiting on the new certificates are not at any immediate risk. Standard Windows updates keep installing normally, and the certificates will arrive automatically once a device shows enough successful update signals. If you want to check your own status, open Windows Security > Device Security, and look under Secure Boot for a green checkmark, yellow warning, or red alert.
Other fixes shipping in the normal rollout
Office applications running in virtualized environments are more stable, both while in use and when closing.
File Explorer no longer incorrectly marks files on a DFS mapped drive as originating from the internet after a device starts offline and later reconnects, which had been triggering a false “this file could harm your computer” warning in the Preview Pane along with an unexpected Mark of the Web on copied files.
File History backups to network shares over SMB are fixed too. Backups were failing with a false “invalid credentials” error even when the credentials were correct, and that is resolved now.
AI components are updated in the background
The August update refreshes the internal AI components Windows 11 uses across the system to version 1.2607.840.0, covering Image Search, Content Extraction, Semantic Analysis, and the Settings Model. These update silently and do not need any action from you.
Servicing stack update and known issues
Microsoft is shipping servicing stack update KB5101711 (build 26100.8962) alongside this release, which improves the reliability of the Windows update installation process itself.
As of this writing, Microsoft says it is not aware of any known issues with this update, a welcome change after July’s update briefly caused shutdown and overheating problems on some Dell PCs before Microsoft shipped an emergency fix.
How to install the August 2026 Patch Tuesday update
Go to Settings > Windows Update > Check for updates to grab it. Your PC moves to build 26200.9165 if you are on 25H2, or 26100.9165 on 24H2, once installed. Turning on “Get the latest updates as soon as they’re available” can help it appear sooner.

Given how much of this update is gradual, do not be surprised if some of the smaller items above, particularly the File Explorer file size change or the touchpad gestures, take a few days to show up even after installing. Yes, this isn’t a feature-rich update, but if Microsoft keeps shipping quality fixes like this every month, Windows 11 ends up a noticeably stable OS by the end of the year.
