System Update Readiness Tool fixes Windows Update errors

To fix errors that occur when you use Windows Update, download the System Update Readiness Tool, and then install and run the tool. The tool scans for inconsistencies on your computer and fixes them as it’s being installed. See What Windows Update errors that can be fixed by the System Update Readiness Tool and What the System Update Readiness Tool does.

Important Although it typically takes less than 15 minutes to run the scan, it might take much longer on some computers. Even if the progress bar seems to stop, the scan is still running, so don’t cancel the process.
