Microsoft continuously withdrew two problematic service stack updates (KB4601390 & KB4601392)

The service stack update is used by Microsoft to update certain basic components of the Windows 10 system. Usually, the patch can only be installed after the service stack is updated.

The servicing stack is provided separately from the cumulative update, which often causes some users to fail to install the cumulative update because the servicing stack is not installed correctly.

So Microsoft has decided to merge the service stack with the cumulative update starting next month, and the two updates are directly integrated into a patch package to push and install to users.

This can greatly improve the success rate of the cumulative update installation and reduce errors such as stuck or other abnormalities, but the cumulative update this month has errors.

According to a support bulletin issued by Microsoft, some users may be stuck at 24% progress when installing routine updates. Microsoft subsequently confirmed that this was caused by the service stack.

This issue mainly affects Windows Server 2016 and Windows 10 LTSB 2016 long-term support versions, other versions seem to be unaffected at present.

The service stack update in question includes KB4601390 and KB4601392, and Microsoft immediately withdrew it after discovering that KB4601390 was faulty.

Unfortunately, there are still problems with KB4601392 as a repair version, so Microsoft withdrew KB4601392 to prevent users from installing the update. At present, Microsoft has withdrawn all the problematic service stack updates.

Some users have already received the Windows update and installed a problematic service stack update. However, Microsoft cannot actively delete the update.

Therefore, users who encounter this problem should first try to manually delete the problematic service stack update. If it cannot be solved, they may need to use the command prompt.

Among them, KB4601390 can be deleted through the control panel. In theory, the cumulative update KB4601331 can be installed normally after deleting it.

But if it still fails to install normally, users have to reset the WindowsUpdate service. Microsoft has provided a supporting document to tell users what to do.
