If a Windows update is followed by crashes, failed sign-ins, broken drivers, networking problems, or a boot loop, remove the update that most closely matches when the trouble began. When Windows still starts, use Settings > Windows Update > Update history > Uninstall updates (Windows 11) or Settings > Update & Security > Windows Update > View update history > Uninstall updates (Windows 10). If Windows will not start, use Windows Recovery Environment (WinRE): Troubleshoot > Advanced options > Uninstall Updates.
Back up important files first and find your BitLocker recovery key before entering recovery tools. Removing a security update can expose the computer to the vulnerability it fixed and, in some cases, create data-loss risk. Treat uninstalling as a targeted, temporary troubleshooting step—not routine maintenance—and reinstall a corrected update when Microsoft supplies one.
Confirm that an update is the likely trigger
A problem that appears immediately after an update is a reasonable reason to investigate that update, but timing alone does not prove causation. A driver change, third-party software installation, failing storage, or an unrelated hardware fault can occur at the same time. Use Windows’ update history and your own timeline before removing anything.
Match the update to the first symptom
- Note the first time the failure occurred and what changed: a blue screen, application crashes, loss of Wi-Fi, a black screen, sign-in failure, or a boot loop.
- Open the update history and identify the newest quality update (the normal cumulative monthly update) and any recent feature update (a larger Windows version upgrade).
- Compare the install dates with the first symptom. This is a troubleshooting inference, not proof that the update caused the failure.
- If the issue began days later or affects only one application, investigate that application’s updates, drivers, and hardware before removing a Windows component.
Back up and prepare recovery access
- Copy documents, photographs, browser exports, password-manager data, and other irreplaceable files to a separate drive or approved cloud location. A rollback can fail, and recovery actions can make an existing storage problem worse.
- If BitLocker or another device-encryption feature is enabled, retrieve the recovery key from the account or organization that manages the PC. WinRE may request it before it will access the Windows volume.
- Keep the power adapter connected. Do not interrupt an uninstall or recovery operation while the computer is restarting.
- For a work or school device, check with the administrator first. Policies may block removal, and the update may be required for compliance.
Choose the least disruptive recovery option
Microsoft’s recovery guidance moves from actions that change the least to actions that change the most. Use the row that matches your situation rather than jumping directly to a reset or clean installation.

| Option | Does Windows boot? | What it changes | Effect on apps, files, and settings | Important conditions |
|---|---|---|---|---|
| Uninstall a quality update in Settings | Yes | Removes one recent cumulative update | Designed to preserve personal files, installed apps, and settings | Some updates cannot be removed; back up first |
| Uninstall a feature update in Settings or WinRE | Usually; WinRE works when it does not | Rolls Windows back to the previous feature version | Broader system rollback; recent changes may not remain | Available only for a limited rollback window and when Windows retains the previous version |
| System Restore | Usually, or through WinRE | Restores system files, drivers, and settings to a restore point | Personal files are normally preserved; applications and drivers installed after the point can be removed | Requires a suitable restore point |
| Fix problems using Windows Update (Windows 11) | Yes | Reinstalls the current Windows version to repair system files and components | Microsoft says it preserves apps, files, and settings | Keep the PC powered and connected to the internet |
| Reset this PC or reinstall from media | Not necessarily | Rebuilds Windows, with an option to remove apps and potentially files | Most disruptive; review every retention choice | Use only after less disruptive recovery paths fail and you have a verified backup |
Microsoft’s Windows Update FAQ states, “We don’t recommend that you remove any installed updates,” and notes that not all updates can be removed. That warning matters even when an update appears to be the cause: remove only the specific update needed to test or restore stability.
Uninstall an update when Windows still starts
Windows 11
- Open Start > Settings.
- Select Windows Update in the left pane.
- Choose Update history.
- Scroll to Related settings and select Uninstall updates.
- Find the update whose installation date matches your troubleshooting timeline. The list may show a knowledge-base identifier such as “KB” followed by numbers.
- Select Uninstall, confirm, and allow Windows to restart. Do not power off while the rollback is running.
Windows 10
- Open Start > Settings.
- Go to Update & Security > Windows Update.
- Select View update history.
- Choose Uninstall updates.
- Select the suspected update, choose Uninstall, confirm, and restart when prompted.
What to do after the restart
Reproduce the original failure once, under the same conditions, rather than making several changes at once. If the problem is gone, pause additional troubleshooting long enough to record the removed update’s KB number and the result. Check Windows Update for a replacement or revised release; leaving the computer without an important fix is not a permanent solution.
If the uninstall entry is absent, Windows has marked that package as non-removable, the rollback window has expired, or a servicing dependency prevents removal. Do not delete files from C:WindowsSoftwareDistribution or the component store as a substitute; those folders are part of Windows servicing and careless changes can prevent future updates.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Uninstall an update when Windows will not boot
Use Windows Recovery Environment (WinRE) when normal startup fails. WinRE can appear automatically after repeated failed starts, or you can deliberately enter it from the sign-in or desktop screens.
Reach WinRE from Windows 11
- Open Start > Settings > System > Recovery.
- Next to Advanced startup, select Restart now.
- Confirm the restart. The PC opens the recovery menu.
Reach WinRE from Windows 10
- Open Start > Settings > Update & Security > Recovery.
- Under Advanced startup, select Restart now.
If Windows cannot reach Settings, turn the computer on and allow startup to fail, then repeat the power-on process until Windows displays its automatic-repair or recovery screen. Use this forced route only when ordinary startup is unavailable; repeatedly cutting power during a normal Windows session can damage data.
Use the WinRE uninstall command
- At the recovery menu, select Troubleshoot.
- Choose Advanced options.
- Select Uninstall Updates.
- Choose Uninstall latest quality update for a recent cumulative update, or Uninstall latest feature update when the trouble began after a major Windows version upgrade.
- Authenticate with an administrator account if requested. Enter the BitLocker recovery key if the encrypted drive is locked.
- Confirm the operation and select Done or Restart when WinRE reports completion.
WinRE presents only the rollback choices that are available on that installation. If one choice fails or is not listed, do not assume the other type of update was responsible; continue with the recovery sequence below.
Understand the security-update risk before removal
Microsoft’s support guidance says, “Before uninstalling a security update, make sure you understand the risks.” A security update can close a remotely exploitable flaw, protect credentials, or correct a weakness in a built-in service. Removing it restores the vulnerable code while the computer is connected to networks, removable media, and other devices.
Use this decision test:
- Severity: Is the failure preventing work, data access, or startup, rather than causing a minor inconvenience?
- Evidence: Does the affected update align closely with the first symptom, with other likely causes checked?
- Alternatives: Have you tried a driver rollback, application repair, System Restore, or another supported fix that does not remove a security fix?
- Containment: Can you temporarily limit network exposure and use the computer only for recovery while waiting for a corrected update?
- Replacement: Will you monitor Windows Update and reinstall a fixed package as soon as Microsoft publishes one?
Microsoft’s security guidance published October 14, 2024 (KB5040677) warns that uninstalling a security update can create wider security exposure and potential data-loss risk. On a managed system, involve trusted IT support rather than making an undocumented exception.

If uninstalling is unavailable or does not solve the problem
Keep the changes isolated and move through the least disruptive supported path that fits the symptom. The following sequence is not a reason to perform every step; stop when the original failure is resolved.
1. Run built-in troubleshooters and check drivers
Use the relevant Windows troubleshooter for networking, audio, printing, or Windows Update. In Device Manager, inspect hardware that failed after the update and use the device’s Roll Back Driver option when it is available. A driver rollback addresses a driver change without removing the entire Windows update.
2. Reinstall the current Windows 11 version
On supported Windows 11 installations, open Settings > System > Recovery and use Fix problems using Windows Update when that option is shown. This reinstalls the current version to repair system files and components while Microsoft says preserving apps, files, and settings. Keep the computer connected to power and the internet until it finishes. The option may not appear on every edition, managed device, or Windows build.
3. Try System Restore
Open System Restore from Windows or choose it under Troubleshoot > Advanced options in WinRE. Select a restore point created before the problem began, review the affected programs and drivers, and confirm only after verifying the date. System Restore is not a personal-file backup and cannot recover files that were already damaged or deleted.
4. Go back after a feature upgrade
If the issue followed a recent feature upgrade and Windows still retains the previous version, use the Go back option in the Recovery settings. This rolls back a broader Windows release, not just one monthly quality package, and availability expires after the previous installation files are removed.
5. Reset or reinstall only as a last resort
Reset this PC can reinstall Windows while keeping personal files or remove everything, depending on the choice you make. A USB or downloaded installation image can perform a clean reinstall, but it can also erase applications, settings, and data. Confirm a verified backup, record activation and application licenses, and understand which disk and partitions the installer will change before proceeding.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Repair system files from an elevated Command Prompt
Microsoft’s Windows troubleshooting guidance documents Deployment Image Servicing and Management (DISM) followed by System File Checker (SFC) for update-related corruption. Use these commands only if you are comfortable opening an elevated Command Prompt and have a backup.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errors- Sign in with an administrator account. Search for Command Prompt, right-click it, and choose Run as administrator. In WinRE, select Troubleshoot > Advanced options > Command Prompt if that option is available.
- At the prompt, run
DISM.exe /Online /Cleanup-image /Restorehealth. Wait for it to finish; it can take substantial time and may require Windows Update or another repair source. - When DISM completes, run
sfc /scannow. - Restart and test the original symptom. If Windows is offline in WinRE, the
/Onlinetarget may not refer to the installed Windows volume; stop rather than guessing drive letters, and use the graphical recovery options or qualified support.
These commands repair component and system-file integrity; they do not selectively remove a problematic update. If the update itself is the trigger, use the uninstall paths first or continue with System Restore.

Use recovery media when the built-in environment is unavailable
Microsoft documents a Windows recovery drive: removable recovery media that can start recovery tools when the PC cannot boot. Creating one requires a blank USB flash drive, and the process can erase that drive’s existing contents. Label it and store it where it is available for the affected PC.
A USB recovery drive is a fallback for reaching WinRE or repairing startup; it is not required for the ordinary Settings-based uninstall. Microsoft does not specify a particular capacity, speed, or brand for the general recovery-drive procedure, so do not buy a drive on the assumption that a particular specification is mandatory.
Windows 10 timing and support status
Microsoft ended Windows 10 support on October 14, 2025. After that date, Microsoft says it no longer provides free Windows Update software updates, technical assistance, or security fixes for Windows 10. The uninstall steps above can still work on an existing installation, but removing an update from an unsupported system leaves fewer supported repair and security options. Plan migration or an organization-approved support arrangement rather than relying on repeated rollbacks.

The update is listed but Uninstall is disabled
Some packages are permanent, superseded, required by servicing, or outside their rollback window. Record the KB identifier, try System Restore or a supported repair reinstall, and avoid manually deleting package files.
WinRE asks for a BitLocker key
That is expected when the encrypted volume must be unlocked for recovery. Retrieve the correct key before continuing. Repeatedly entering an incorrect key will not bypass encryption; if the key cannot be found, contact the device owner or administrator before attempting a reset.
The computer boots after removal but fails again when Windows Update runs
The replacement package may contain the same unresolved defect, or another driver or application may be responsible. Pause automatic updates only long enough to obtain support or a fixed release, document the KB number, and keep the system protected with compensating controls. Do not treat a permanent block on security updates as the solution.
The problem remains after the update is removed
Reinstalling an older state does not undo hardware failure, malware, a damaged user profile, or an incompatible application. Restore the removed update if appropriate, then investigate those alternatives with Event Viewer, vendor diagnostics, driver history, and application logs. If the machine is unstable, preserve data first and escalate to professional support.
Quick Recap
A practical decision checklist
- Record the symptom, first occurrence, Windows edition, and update KB number.
- Back up important files and locate the BitLocker recovery key.
- Use Settings when Windows starts; use WinRE when it does not.
- Choose quality versus feature rollback based on the update type shown by Windows.
- For a security update, remove it only for a serious, credible failure after considering safer repairs.
- Restart, test one change at a time, and document the result.
- Reinstall a corrected update promptly and avoid leaving a vulnerable system exposed.
- If removal fails, progress from troubleshooters and repair reinstall to System Restore, feature rollback, reset, or reinstall media in that order of disruption.
