I've always been nervous with Windows updates.  The first time I had to reformat a computer was when a Windows ME update went into an infinite loop.  Things like that were so much more complicated before all the guides and Youtube videos.

Windows ME was soo soo bad though.. like Billy G how do you screw up this much?

With the kicking the can down the road Microsoft is doing with little in the way of changes what reason is there not move to 21H1.

Also installed "Feature update to Windows 10, version 21H1"
 
 
 
No problems so far.

21H1 (19043.1023)  All good so far.  Didn't like the new taskbar feature "News and Interests" so turned if off.

Only a couple hours in these updates and everything is running fine.  That includes the optional feature update also.

updated laptop W10 Home & a Desk top W10 Pro ---> to 21H1
 
 
then installed:
2021-05 Cumulative Update Preview for Windows 10 Version 21H1 for x64-based Systems (KB5003214)
 
No issues after couple of days of testing

Question on the 21H1 update.  Is it like some of the previous "minor" updates where it installed more like a monthly patch?  Or is it one of the kinds that essentially installs a new Windows folder, migrates your stuff, and leaves a Windows.old folder for a few weeks?  Just debating to install tonight before a group gaming thing or not since the more in depth "migration" style requires me to fix a few things after vs. just logging in and resuming normal use.

Nevermind got my my answer.  It installs just like a monthly update, installed it in like 2 minutes no issues so far.

Glad you figured it out.  

I am glad that this is exactly the case. And sometimes the installation is delayed for several hours. And then you still need to configure some elements of the system.
