Frequently Asked Questions

Why does the Windows 11 update roll back after restarting?

A rollback happens when Windows detects a critical error or file corruption during the installation process. It safely restores the system to its previous state to prevent your computer from becoming unbootable. This is often caused by corrupted download caches or conflicting background services.

Where can I find the specific error code for a failed Windows update?

To find the error code, go to Settings > Windows Update > Update history. Under the 'Quality Updates' or 'Other Updates' section, you will see the failed KB5033375 update along with a hexadecimal error code (e.g., 0x800f0922).

Is it safe to delete the SoftwareDistribution folder?

Yes, it is completely safe. The SoftwareDistribution folder stores temporary files required for installing Windows Updates. By renaming or deleting it while update services are stopped, you force Windows to recreate the folder and download fresh, uncorrupted update files.
