update after halting it on Friday evening. The tech giant
published this cumulative update on Thursday (March 18) to

Now, after spending some time squashing those bugs, the rollout
of the KB5001649 update for Windows 10 is resuming, presumably
with a fix in place.
According to Microsoft Update Catalog, the optional cumulative
update weighs in at around 400MB for users still on February
2021 cumulative update. It is quite a bit smaller for those
already picked up that botched
March 2021 cumulative updates.
It’s worth noting that Windows 10 KB5001649 is designed to fix
the remaining printing problems and it’s only starting to roll
out, which means it’s only a matter of time until Microsoft
starts pushing it to everyone in all regions.
According to our tests, the cumulative update started rolling
out only a few hours ago (2 PM ET, March 21), it may take a few
hours or one day before you see the notification on the Windows
Update page, as shown in the screenshot below.
So far the users that did receive the KB5001649 update have
reported no further issues.
