The error "Something didn't go as planned. No need to worry - undoing changes" in Windows 11 indicates a failed update rollback caused by corrupted system files, conflicting services, or insufficient storage. To resolve this, you must repair the Windows Update components using built-in diagnostic tools and ensure critical background services are running correctly before retrying the installation process.
Understanding the Rollback Error
When Windows 11 attempts to install a major feature update or cumulative patch, it creates a backup of your current system state. If the installation encounters a critical failure—such as a driver conflict, a missing registry key, or a service that fails to start—the system automatically triggers a rollback. This is a safety mechanism designed to prevent your computer from becoming unbootable. However, if the underlying cause is not addressed, the same error will recur every time you attempt an update. The message specifically mentions that changes are being undone, which means the system has already reverted to the previous version, but the update files remain in a broken state on your drive.
Enabling Critical Services for Updates
The title of this guide highlights the role of services. Several background processes are essential for downloading and applying updates. If these services are disabled or set to manual startup, the update engine cannot function properly. You can verify their status through the Services management console. Open the Run dialog by pressing
Win + R, type
services.msc, and press Enter. Look for the following services:
- Windows Update (wuauserv): This is the core service responsible for managing updates. It should be set to Automatic (Delayed Start) and have a Status of Running.
- Cryptographic Services (cryptsvc): This service validates digital signatures of update packages. If it is stopped, updates may fail integrity checks.
- Background Intelligent Transfer Service (BITS): BITS handles the download of update files in the background. It must be enabled to allow data transfer.
- Setup Manager Service (setupsvc): This service manages the installation phase of updates. Ensure it is running during the update window.
If any of these services are stopped, right-click them, select Properties, change the Startup type to Automatic, and click Start. After enabling them, restart your computer to apply the changes. For more insights on how system stability affects updates, see our guide on

Using the Windows Update Troubleshooter
Microsoft provides a dedicated diagnostic tool that can automatically detect and fix common issues preventing updates from installing. This tool checks for problems with the update agent, file corruption, and service configurations. Navigate to Settings > System > Troubleshoot > Other troubleshooters. Locate the Windows Update option and click Run. The tool will scan your system for errors related to the update process. If it finds issues, follow the on-screen instructions to apply fixes. This step is often sufficient to clear minor glitches that trigger the rollback message.
Repairing Corrupted System Files
If the troubleshooter does not resolve the issue, corrupted system files may be interfering with the update process. You can use the System File Checker (SFC) and Deployment Image Servicing and Management (DISM) tools to repair these files. Open Command Prompt as an administrator by searching for
cmd in the Start menu, right-clicking the result, and selecting Run as administrator. First, run the SFC scan by typing
sfc /scannow and pressing Enter. Wait for the process to complete; if it finds corrupt files, it will repair them automatically.
Next, run the DISM commands to restore the system image. Execute the following commands one by one, waiting for each to finish before starting the next:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth
These commands check the health of the Windows component store and replace corrupted files with healthy copies from Microsoft's servers. Once completed, restart your PC and try updating again. If you suspect deeper issues with the update cache, consider reviewing solutions for

Clearing the Update Cache
Sometimes, partially downloaded update files become corrupted and cause conflicts during installation. Clearing the SoftwareDistribution folder forces Windows to re-download fresh copies of the update files. Stop the Windows Update service by opening Services and stopping
wuauserv. Then, navigate to
C:\Windows\SoftwareDistribution and delete all contents of the Download and DataStore folders. Restart the Windows Update service and your computer. This ensures that no old, broken files interfere with the new installation attempt.
Frequently Asked Questions
What causes the 'undoing changes' message?
This message appears when Windows detects a critical error during the installation phase, such as a driver crash or a service failure. The system then reverts to the previous state to protect your data and ensure bootability.
Can I skip the rollback and force the update?
No, forcing the update while the rollback is active can lead to system instability or a blue screen of death. You must wait for the rollback to complete fully before attempting any further troubleshooting steps.
How do I manually restart the Windows Update service?
Open the Services app (
services.msc), locate Windows Update, right-click it, and select Restart. If the service is not running, choose Start instead. This refreshes the connection to Microsoft's update servers.
Is it safe to delete the SoftwareDistribution folder?
Yes, it is safe to delete the contents of this folder, as Windows will recreate it with fresh files upon the next update check. However, you must stop the Windows Update service first to prevent file access errors.
What if DISM fails to repair files?
If DISM reports that it cannot fix the images, you may need to perform an in-place upgrade using the Media Creation Tool. This method reinstalls Windows while keeping your files and applications intact, effectively replacing all system files with fresh ones.
