The feature becomes inaccessible when severe corruption within Windows Update components prevents the automated retrieval of the system repair image.
The manual equivalent to that tool is performing an In-Place Upgrade using the official Windows 11 ISO. This will completely repair and replace all damaged system files while keeping all your personal files, apps, and settings 100% safe.
Here are the instructions:
(If you have a third-party antivirus installed, temporarily disable it during the entire procedure.)
1 = Download the ISO file to perform the procedure:
- Access the link below;
https://www.microsoft.com/en-us/software-download/windows11
- Under Download Windows 11 Disk Image (ISO) for x64 devices, click Select download and select Windows 11 (multi-edition ISO for x64 devices);
- Click Download;
- Choose the language and click on Confirm;
- Then, click 64-bit Download.
- Wait for the download to finish and proceed to the procedure below.
2 = After downloading the ISO, do the following:
- Double-click the ISO to run;
(After running the ISO, you may need to double-click the Setup file to start the procedure.)
- On the Install Windows 11 screen, uncheck I want to help make the installation of Windows better and select Change how Windows Setup downloads updates;
- On the next screen, select Not right now and click Next;
- Accept the terms of use;
- On the Ready to install screen, select Choose what to keep and select what you want to keep.
(It is in this step that you must check Keep personal files and apps so that all your data is kept.)
- Click on Install and wait for the procedure to finish. Your computer may restart several times.
Note: After the final reboot, Windows Update might offer you the latest update again. This is completely normal because ISO media usually needs the newest cumulative patch applied after installation. Now that the system components are healthy, just click Download & Install, and it should complete without errors.
Please let me know how it goes.
