Microsoft has pulled one more buggy Windows 10 servicing stack update (SSU), KB4601390, because it blocked customers from installing this month’s security and Cumulative Updates.
The company resolved the update installation problems by releasing a new servicing stack update (SSU), KB5001079.
Windows 10 SSUs provide servicing stack fixes, the component used by Windows 10 to download and install updates correctly.
They can be automatically delivered to devices via Windows Update or mass deployed through the Windows Server Update Services (WSUS) on enterprise networks.
You can also install them manually using standalone update packages available through the Microsoft Update Catalog.
Windows updates getting stuck
The removals were caused by Windows 10 security updates getting stuck during the installation process at 24%.
“After installing the SSU KB4601390, installation of the Cumulative Update from Windows Update might not progress past 24%,” Microsoft said on Wednesday, after acknowledging the issue.
Since Microsoft removed the buggy KB4601390 SSU, it will no longer be offered through the Microsoft Update Catalog or Windows 10 devices searching for updates through Windows Update.
Customers must install the new KB5001079 SSU before attempting to installing the February 9, 2021 security updates.
