Windows 10 May 2020 update is now available

Installed new May 2020 update - after getting a notice that my system was not ready to install the update from Microsoft - and it worked fine for several days. Yesterday, my Outlook stopped responding when sending an email, then froze. When I tried to close the program it would not, even from the task manager. After than Windows stopped working. No programs would launch, both Microsoft and non-Microsoft programs.

Shut down and restarted my Surface Pro 3 and it started painfully slow and no programs or services would start. Tried troubleshooting several times to fix the problems and Windows 10 May 2020 just would not work. Managed to return the system to a previous build, 1909. Everything is now working fine, but I would like to know what may have caused this major issue.

Well What may have caused this major issue is that, with respect you said it yourself , your computer wasn't ready to install the update , and you basically forced the update , there is a reason that Microsoft are staggering the update for 2004 , and that is to avoid a barrage of people complaining that their systems no longer work correctly , or that their piece of video editing software worked with previous version now doesn't work .  If you did not see Windows 10 updates when you clicked on check for updates then your system wasn't read for the May 2020 update.  And that alone should have told you best stay clear .

How much data is required to download this update? Can I directly update my windows from updator? I want to update my windows which I am using for some time now. Please anyone can tell me some simple new changes in this update?

Mainly change: Headaches.

Suggestion: Wait 6-9 months

Hello guys i just installed the new windows update which changes the version from 1909 to 2004 but i am unable to do certain things due to their not having a media feature pack for the version 2004 anyone know when it is coming out?

I had the same issue when first doing the update through Windows Update.  When that failed I used the Windows Update Assistant and it installed just fine.  Though it messed a few things up for me.

Since updating my pc to Windows version 2004, my Xbox 360 wireless controller drivers are not recognized by Windows and same goes for the wireless receiver. And I have done everything like I have done before to get them to work to no luck.  Now I'm going to have to spend $150 for an Xbox One wireless controller and receiver.  Unless someone has a fix for this.  I'm not happy about having this much trouble.  Even though the drivers are already built into the OS, they just don't work.
