Software Windows 11 How-To

How to Check Which Windows 11 Features You've Actually Received

Install KB5124008 and you might see the new taskbar position setting immediately — or not see it for another week, even though a coworker with the exact same build number already has it. That's normal, and there's a straightforward way to check exactly where your PC stands: your build number, and then each feature individually.

Your build number tells you what's installed; it doesn't tell you what's switched on yet.

Watch: Microsoft's own release notes for build 26100.9445 / 26200.9445.

Where to find your current build number

Check Your Build Number First

Go to Settings > System > About and look at the "OS Build" line. This tells you whether the update itself has installed, which is a separate question from whether any individual feature inside it has activated on your PC.

  1. Open Settings (Win + I).
  2. Go to System > About.
  3. Check the OS Build field under Windows specifications.

25H226200.9445KB5124008

If your build number matches one of the first two rows, the update itself has installed successfully — the taskbar, Start menu, and Search changes are technically present in your system files. Whether they're switched on for you yet is the next question.


Check Each Feature Directly, Not Just the Build Number

Checking Settings directly is more reliable than assuming a feature is active just because the update installed.

Because Microsoft activates individual features gradually through Controlled Feature Rollout (CFR) even after everyone is on the same build, the only reliable way to know what you personally have is to check each setting directly:

FeatureWhere to Check
Taskbar positionSettings > Personalization > Taskbar > Taskbar behaviors
Taskbar sizeSame menu, just below Taskbar position
Start menu sizeSettings > Personalization > Start
Search web/Store togglesSettings > Privacy & security > Search

If a setting listed above doesn't appear at all — not grayed out, just missing — that feature hasn't reached your PC yet, even if your build number is correct and matches what's listed in the table above.


Can You Make Features Show Up Faster?

Safe, Simple Steps
  • Turn on "Get the latest updates as soon as they're available" in Windows Update settings
  • Restart your PC once after installing the update
  • Check Windows Update for any follow-up optional updates
Advanced, Not for Everyone
  • Use ViVeTool with the specific feature ID to force-enable it early
  • Requires comfort with Command Prompt and accepting some added risk

None of the safe steps guarantee a faster rollout — Microsoft controls the schedule server-side, based on rollout data it collects across the entire Windows 11 install base — but they remove any client-side reasons a feature might be delayed further than necessary, which is the most any individual user can realistically influence.


Confirming Your Windows 11 Edition and Update History

While you're in Settings > System > About, it's also worth glancing at the "Windows specifications" table for your edition (Home, Pro, Enterprise, Education) and version (23H2, 24H2, 25H2), since both affect what you're eligible for. If you want a full log of every update your PC has installed, Settings > Windows Update > Update history lists them chronologically, which is useful for confirming exactly when KB5124008 (or KB5122880, if you're on 23H2) actually installed, in case you're troubleshooting a feature that should have appeared by now.


What If Your Build Number Doesn't Match Either Row?

If Settings > System > About shows a build number lower than 26100.9445, 26200.9445, or 22631.7582, the update hasn't installed yet. Go to Settings > Windows Update > Check for updates and install anything offered. If nothing shows up despite waiting, and you're confident your device should be eligible, Microsoft's Update Catalog also hosts standalone installer files for KB5124008 and KB5122880 that can be downloaded and run manually — a reasonable fallback if the automatic rollout to your device seems unusually delayed compared to what Windows Update itself is offering.


The Reasoning Behind Staggered Rollouts

It's worth understanding why Microsoft doesn't just switch every feature on for everyone the moment an update installs. Windows 11 runs on an enormous range of hardware configurations, driver combinations, and third-party software setups, and a change that works flawlessly in Microsoft's internal testing can still surface an edge case once it meets millions of real-world PCs. Controlled Feature Rollout lets Microsoft activate a feature for a small percentage of devices first, watch for crash reports, performance regressions, or support tickets, and only expand it further once the data looks clean — pausing or rolling back a problematic feature for a subset of users rather than for everyone.

The trade-off is exactly the confusion this guide addresses: your PC and a colleague's PC can be running literally the same build number while showing different Settings screens for weeks at a time, with neither device doing anything wrong. That's the intended behavior of the system, not a sign something has gone wrong with either device, and it's the same reasoning Microsoft has applied to feature rollouts across every Windows 11 release since launch, not something unique to this particular update.


How Long Should You Actually Expect to Wait?

Based on patterns from previous Windows 11 feature rollouts, expect visible UI changes like taskbar position to reach a meaningful share of eligible devices within one to three weeks of the update's release, with the rollout continuing to expand for a period after that. Security fixes are the exception to all of this — those apply universally and immediately upon installing the update, with no gradual activation involved, since there's no reason to stagger a fix for an actively exploited vulnerability — every eligible device gets those the moment the update finishes installing, well before any cosmetic feature has finished its gradual rollout.


The winver Command Shortcut

If opening Settings feels like overkill just to check a build number, press Win + R, type winver, and press Enter. This opens a small "About Windows" dialog showing your exact build number and version without navigating through Settings at all — a faster route when you just need a quick number to compare against a support article or forum post, rather than the fuller Windows specifications table that Settings > System > About provides, which also includes your edition, installed RAM, and system type alongside the build number.

Frequently Asked Questions

Is there a single screen that shows every new feature I have?

Not currently. Windows 11 doesn't have a consolidated "what's new for me" screen — you need to check each relevant Settings page (Personalization, Privacy & security) directly to confirm which individual features are active.

Does a higher build number always mean more features are active?

Not necessarily right away. The build number confirms the update installed, but individual features within it can still be pending activation through Microsoft's gradual rollout, so two devices on the same build can differ.

Will restarting my PC force pending features to appear?

It can help in some cases, since certain feature flags only get evaluated at startup, but it's not guaranteed. Rollout timing is primarily controlled server-side by Microsoft, not purely by local restarts.

Do Windows Insider Program members get features earlier than everyone else?

Generally yes. Insider Program builds typically receive new features ahead of the general release, which is part of why Insiders often report seeing changes weeks before they show up for mainstream Windows 11 users on the same nominal build.

What's the fastest way to just check my build number?

Press Win + R, type winver, and press Enter for a quick popup with your build number. For the full version and edition details, Settings > System > About gives you the complete Windows specifications table instead.
