It seems that Windows patch KB 3150513 patch will never leave our side. Microsoft keeps insisting users download the much-hated “upgrade enabling” patch for the 10th time to its latest version of Windows.
The patch keeps coming back for more
Over the past year, Microsoft has issued and re-issued the KB 3150513 patch 10 times and each time, this nasty visitor appears without any notification or warning. There isn’t even an entry on the Windows Update list or on the Windows 10 Update list, but none of this really matters as Microsoft still pushes it out using Automatic Update.
This is being pushed out onto Windows 7, 7, 8.1, Windows 10 1511, and now it’s happening again on 1607 systems, no matter if we like it or not.
Microsoft’s explanation on the KB patch
Last year, Microsoft’s KB article described the patch as it follows:
This update provides the latest set of definitions for compatibility diagnostics that are performed on the system. The updated definitions will help enable Microsoft and its partners to ensure compatibility for all customers who want to install the latest Windows operating system. Installing this update also makes sure that the latest Windows operating system version is correctly offered through Windows Update, based on compatibility results.
The article has also listed the files that are included in the patch: Appraiser.sdb, Appreiaser_data.ini, and Appraiser_telemetryrunlist.xml. The KB patch is only needed for upgrading to Windows 10 and doesn’t provide anything useful for the current Windows 7 users.
If your plans involve upgrading your current operating system to Windows 10 Creators Update, you might also want to consider installing the patch. Even if you don’t do it, history has already proven that it will only come back again to haunt us.
