KB5101650 is the July 2026 security update for Windows 11 24H2 and 25H2. Microsoft has now resolved its confirmed Dell and Intel Innovation Platform Framework (IPF) compatibility hold with KB5121767, a July 18 cumulative out-of-band update for affected devices. Microsoft says affected PCs can install KB5121767 when Windows Update offers it, while unaffected devices need no action. BSODs, display color changes, audio trouble, and failed installations remain user-reported symptoms rather than broadly confirmed KB5101650 defects. Match your device and symptom to the steps below instead of removing or forcing an update preemptively.
KB5101650 problems: what is confirmed?
| What you see | Status and safest next step |
|---|---|
| KB5101650 was withheld on a Dell PC with an Intel IPF driver | Resolved July 18. Microsoft says affected Windows 11 25H2 and 24H2 devices can now install the cumulative KB5121767 update when Windows Update offers it. The resulting builds are 26200.8894 and 26100.8894. |
| KB5121767 is offered on a non-Dell or otherwise unaffected PC | No special action is required for the Dell fix. Microsoft says unaffected devices do not need to seek out KB5121767. If Windows Update offers it through the normal channel, follow the displayed option or your administrator’s policy rather than downloading a Catalog package solely for this issue. |
| Unexpected shutdowns, poor performance, high heat, or faster battery drain on an affected Dell model | Microsoft resolved this specific IPF issue in KB5121767. Install it when offered, complete the requested restart, then recheck the Intel IPF device and the original symptom. Do not assume it fixes unrelated BSOD, display, audio, or installation reports. |
| BSOD or boot loop after KB5101650 | User-reported, not currently confirmed as a broad Microsoft issue. Record the stop code, disconnect nonessential hardware, and use Windows Recovery Environment to uninstall the latest quality update only if Windows cannot boot. |
| KB5101650 fails, reverts, or shows an installation error | User-reported and may have several causes. Record the exact code, run the Windows Update troubleshooter, check free space and drivers, then use Windows 11’s repair reinstall option before forcing a standalone package. |
| HDR, color, refresh-rate, search, or audio behavior changed | User-reported and hardware-specific. Test the related display, GPU, USB, or audio driver path first. A symptom disappearing after uninstalling the update is useful evidence, but it does not prove every PC has the same defect. |
KB5101650 also contains the fix discussed in our guide to CapabilityAccessManager.db-wal filling a Windows 11 drive. That file-growth fix is separate from the Dell safeguard hold and the newer crash or installation reports.
Before you uninstall or force the update
- Confirm the update and build. Open Settings > Windows Update > Update history and look for KB5101650 or KB5121767. KB5101650 corresponds to builds 26200.8875 and 26100.8875; the Dell/IPF out-of-band resolution KB5121767 moves Windows 11 25H2 and 24H2 to 26200.8894 and 26100.8894.
- Record the exact symptom. Photograph a BSOD stop code, copy the Windows Update error code, and note the time of each shutdown. “It broke after the update” is not enough to distinguish a driver conflict from an update-package failure.
- Back up important files. A repair reinstall normally preserves files and apps, but a backup is still the safer starting point.
- Check the PC maker and model. The confirmed safeguard is limited to some Dell systems with Intel IPF drivers. Do not apply Dell-specific driver advice to an ASUS, Lenovo, HP, custom desktop, or virtual machine.
- Do not use random driver sites or registry cleaners. Firmware and platform drivers must come from the PC manufacturer for the exact model. Generic cleanup tools cannot repair an incompatible firmware-driver interface.
KB5121767 fixes the Dell Intel IPF issue
Microsoft marks the Dell and Intel IPF issue as resolved by KB5121767 and later updates. KB5121767 is cumulative, so an affected device does not need KB5101650 or another previous update installed first. It includes the earlier security and non-security improvements plus the IPF fix.
- Open Settings > System > About and confirm that the PC runs Windows 11 25H2 or 24H2. Note the current build before changing anything.
- Open Settings > Windows Update and check for updates. If Get the latest updates as soon as they are available is enabled, Microsoft says KB5121767 can arrive automatically; otherwise use the offered Download & install option.
- Let Windows Update finish and complete the restart it requests. Afterward, the expected builds are 26200.8894 for 25H2 and 26100.8894 for 24H2.
- Open Device Manager > System devices and recheck Intel Innovation Platform Framework Processor Participant. Confirm whether the yellow warning and the original shutdown, heat, battery, or performance symptom are gone.
- If the warning remains, use Dell Support with the exact Service Tag for current BIOS, chipset, USB-C/Thunderbolt, and Intel IPF packages. Do not uninstall the IPF device or use a bulk driver updater as the first response.
- If KB5121767 stalls, fails, or reverts, record the error code and use the general Windows Update repair branch below. Persistent hardware-specific symptoms should be reported to Dell and Microsoft with the model, build, driver state, and timing.
Microsoft recommends KB5121767 only for devices affected by this issue and says unaffected devices need no action. Prefer Windows Update. Use the Microsoft Update Catalog only when Microsoft or an administrator specifically directs a standalone installation, because the KB can contain multiple MSU files with a required order.
If KB5101650 caused a BSOD or boot loop
A BSOD immediately after the update is a strong timing clue, but the stop code and driver named in the crash still matter. First disconnect docks, nonessential USB devices, external audio interfaces, and other peripherals. If Windows starts, save the minidump and check Reliability Monitor before changing drivers.
If Windows cannot boot, enter Windows Recovery Environment. Choose Troubleshoot > Advanced options > Uninstall Updates > Uninstall latest quality update. You may need the BitLocker recovery key on an encrypted device. This recovery option rolls back the latest quality update; it does not erase personal files.
After Windows starts:
- Save the BSOD stop code and any minidump before it is overwritten.
- Temporarily pause Windows Update instead of disabling the service or blocking updates permanently.
- Install BIOS, chipset, storage, and GPU drivers from the PC or component manufacturer.
- Check Microsoft Release Health for a resolved issue before retrying.
- If the PC still restarts without a blue screen, follow our random restart troubleshooting flow to separate update timing from overheating, power, memory, and driver faults.
Removing a security update also removes its fixes. Keep the pause short, avoid unknown “update blockers,” and reinstall the current cumulative update once the driver or safeguard issue is resolved.
If KB5101650 or KB5121767 will not install or keeps reverting
An installation failure is not the same as the Dell safeguard. If Windows Update offers KB5101650 or KB5121767 but the installation fails, record the exact error code and start with the least destructive checks. KB5121767 is cumulative, so do not install KB5101650 first as a prerequisite.
- Restart the PC and run the Windows Update troubleshooter through the Get Help app.
- Confirm that the system drive has adequate free space and that date, time, and internet access are correct.
- Finish any pending restart and install current manufacturer drivers.
- Open Settings > System > Recovery and use Fix problems using Windows Update if the troubleshooter does not repair the servicing components. This reinstalls the current Windows version while preserving apps, files, and settings.
- Use the Microsoft Update Catalog only when Microsoft or your administrator specifically recommends the standalone package. The KB can include several MSU files that must be installed in the documented order.
If Task Manager shows MoUsoCoreWorker.exe consuming resources while the update is stuck, do not delete the process or system file. It is normally part of Windows Update; use our MoUsoCoreWorker.exe troubleshooting guide to check its path and repair a stalled update workflow.
Display, HDR, refresh-rate, or audio trouble after KB5101650
These symptoms appear in fresh user reports, but they are not listed as general known issues in Microsoft’s current release notes. Treat them as a driver-and-update interaction until stronger evidence exists.
- Record the GPU, monitor, dock, USB controller, or audio interface model and current driver version.
- Test without docks, adapters, and nonessential USB devices.
- Install a current OEM or hardware-vendor driver. Do not use a bulk driver updater.
- If a driver reinstall fixes the symptom, keep that result separate from claims that KB5101650 itself is broadly defective.
- If uninstalling the quality update is the only fix, pause it temporarily and submit the hardware details through Feedback Hub so Microsoft receives a reproducible report.
Should you uninstall KB5101650?
Leave KB5101650 installed when the PC is stable. It is a security update, and scattered reports do not justify a preventive rollback. Uninstall the latest quality update only when the timing and symptom are clear—for example, a repeatable boot failure that disappears after rollback—and after recording the evidence you will need to choose a driver or firmware fix.
For an affected Dell/IPF device, install KB5121767 when Windows Update offers it and verify build 26200.8894 or 26100.8894 after the requested restart. If the PC is not affected, Microsoft says no action is required specifically for this out-of-band fix. For other hardware, continue treating BSOD, install failure, display, and audio reports as symptom-specific troubleshooting cases rather than one universal KB5101650 bug.
FAQ
Is KB5101650 safe to keep installed?
If the PC is stable, do not uninstall KB5101650 preemptively. Microsoft resolved the confirmed Dell/IPF compatibility problem with KB5121767; unrelated BSOD, display, audio, or failed-install reports still need symptom-specific diagnosis.
What is KB5121767, and do I need it on a non-Dell PC?
KB5121767 is a cumulative out-of-band update that fixes the limited Dell and Intel IPF issue and moves Windows 11 25H2 and 24H2 to builds 26200.8894 and 26100.8894. Microsoft says affected devices can install it when offered and unaffected devices need no special action. Windows Update may still offer it automatically when the latest-updates toggle is enabled.
Does KB5101650 cause BSODs?
Users are reporting BSODs after the update, but Microsoft has not confirmed a broad KB5101650 BSOD issue. Preserve the stop code and minidump, check the named driver, and use the Windows Recovery Environment rollback only if the PC cannot start.
Can I pause KB5101650 after uninstalling it?
Yes. A temporary pause is safer than permanently disabling Windows Update. Resume updates after Microsoft or your hardware vendor publishes a relevant fix because leaving a security update removed increases exposure over time.
