Windows 10: KB4515384 can't solve the problems in Windows 10

After the installation of this new upgrade, I've observed this performance:
1. The performance of Windows Defender rises to an amazing comsumption of RAM: 410 Mb.
2. The simple account (my) rises to: 323 Mb.
The two consumptions are unnaceptable.
If you don't have any solution, I'll go to unnistall the last two upgrades.

KB4515384 breaks Action Center

same issue on my PC. I tried install KB4515384 on one of my workstation with no luck. Menu start stopped working with critical error and sign out demand. After uninstall latest CU problem with start
menu was solved but action center won't open now. Windows 10 especially 1903 is the most bugged OS ever. I suggest stay at 18362.295 as long as possible or until all flaws will be finally fixed

 

New install Windows 10 (issue solved)

It's good that you're not experiencing any issues. Unfortunately many folks are, a quick Google search will show the same info im offering the OP.

Heres a couple examples:

It's basically what I mentioned above, small issues here and there ,but nothing to end your day.. for the most part.

I know it's anecdotal, but for my experience 95% of the time it's perfectly fine. The issues I've run into wouldn't be enough for me to roll back , but they would be enough (had I not installed it yet) ,to avoid it for another couple weeks which is why I'm suggesting it to the OP
