Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →A Windows 11 PC can slow down after an update, but the timing alone does not prove the update caused it. Start by checking what is using system resources, then look at startup apps, storage, drivers, and Search indexing. If the slowdown began with a specific update and basic checks fail, Windows provides recovery options—including uninstalling a recent update—but the safest choice depends on your Windows version and the effect you can tolerate.
Why Windows 11 may feel slow after an update
Several problems can produce similar symptoms: high CPU, memory, or disk use; too many apps or browser tabs; low free storage; outdated software or drivers; malware; or background activity. An update may coincide with the slowdown without being its cause. Check what is happening on your PC before rolling anything back.

Windows Search indexing is one possible source of background work, especially if Search or File Explorer activity is high. That does not mean every update triggers a reindex, or that indexing is necessarily responsible for a particular slowdown. Microsoft says initial indexing can take up to a couple of hours, but this is not a guaranteed wait time after an update. Microsoft’s Search indexing guidance explains how the index works.
Check what is consuming resources
- Restart and reduce the workload. Restart the PC, then close apps and browser tabs you are not using. Microsoft notes that having many open apps or tabs can affect performance. Microsoft’s Windows performance guidance covers common causes and checks.
- Open Task Manager. Press
Ctrl+Shift+Esc. In Processes and Performance, look for unusually high CPU, memory, or disk use. In Startup apps, check which programs load when you sign in. Identify a process before closing it; do not end unfamiliar Windows or system processes. - Check Windows and driver updates. Open Settings > Windows Update and check for available updates, including optional driver updates if offered. Updates often include fixes and performance improvements, but installing one is not a guarantee that it will resolve a particular slowdown. Microsoft’s update instructions explain how to check.
- Check free storage. Low disk space can affect performance. Review storage in Settings and use Storage Sense or temporary-file cleanup to remove items you no longer need. Check what will be deleted before confirming cleanup.
- Inspect Search indexing if activity points that way. Open Settings > Privacy & security > Search. Classic indexing covers common user folders by default; Enhanced indexing covers all user folders and files and may use more resources. Microsoft gives a rule of thumb that the index is less than 10 percent of the size of the indexed files. If indexing is in progress, allow it to finish rather than assuming it will resolve on a fixed schedule.
- Scan for malware when there are other signs. If resource use is unexplained or you notice other suspicious behavior, run a malware scan. Malware can consume CPU and disk resources, but a scan is not a substitute for identifying the process or symptom.
Use the least disruptive recovery option that fits
If the PC is still slow, freezing, crashing, or behaving unexpectedly—and the problem clearly began after a particular update—consider Windows recovery guidance. Back up important files before recovery. Not every update can be uninstalled, and options vary by Windows version and by how much they change or remove.

| Option | When it may fit | Availability and impact |
|---|---|---|
| Run a relevant troubleshooter | When symptoms suggest a known Windows problem and you want to try a low-disruption check. | Microsoft lists this among the options for a PC that starts but has problems; the relevant troubleshooter depends on the issue. |
| Reinstall the current Windows version | When Windows itself may need repair and less disruptive checks have not helped. | Available on Windows 11 version 22H2 or later through the recovery guidance described by Microsoft. It preserves personal files, apps, and settings. |
| Uninstall a recent update | When the slowdown started after a specific update and simpler checks have not resolved it. | Not every update can be uninstalled. Removing an update changes the installed Windows state; use Microsoft’s instructions for the applicable update and device. |
| System Restore | When you want to return system state to an earlier point and a suitable restore point is available. | Microsoft lists point-in-time restore for Windows 11 version 24H2 or later in this recovery context. Check what the selected restore point affects before proceeding. |
| Reset this PC | As a later step when other recovery options have failed. | More disruptive: available reset choices differ in whether they retain personal files, apps, and settings. Review the choice carefully before confirming. |
Microsoft also says that going back to a previous Windows version after a version upgrade is available for 10 days. That is a different situation from uninstalling an individual update. For the current choices, version limits, and effects, follow Microsoft’s Windows recovery options. Keep a backup first; if you use Windows Recovery Environment, make sure you can access the BitLocker recovery key when relevant.

Microsoft’s September 8, 2026 release note for Windows 11 version 26H1 security update KB5124012 (OS Build 28000.2954) describes a desktop-loading issue after the August 2026 preview update KB5120996 and subsequent updates. Microsoft says it was observed primarily on Azure Virtual Desktop hosts using FSLogix. Reported symptoms include a black screen after sign-in, the desktop not loading automatically, or Explorer crashes—not a general slowdown on ordinary consumer PCs. Listed mitigations include launching explorer.exe through Task Manager and an enterprise Known Issue Rollback. Microsoft said it was working on a resolution in the release-note content available for this article; check the current note for status before applying an enterprise mitigation.
