Windows Booting very slow after 2004 update ,

You are correct, issue is not caused by hdd or ssd management software in windows., I followed the instructions provided above, I am using ssd I even updated my bios to latest update so far the only thing I did not do is reinstall windows 1909 since. I really hope windows will release a new update soon. My boot time before the 2004 update was 30 seconds now it boot in 60 seconds.

Dear R KennethSmall

My pc run whit SSD but still problems after i use one browser ,if brave google chrome or edge . then if i close the browser i cant open it any more . then i most reboot my pc ... this rebooting need 15,min 34 sec ? , some programes what i have open befor they dont open any more ,, again reboot of 15 min ... if i test my pc no error i test all hardware for new updates , but no new up date need, if i reboot my pc whit out the xxxx what ever problem it reboot in 3 min,  so this is not one HDD or SSD SDD problem 

its clear on windows 2004 update problem and windows 10 2004 have many problem ther are so many bugs in it the best way recovery you  windows go back befor the update IF ? you still can and wait whit this update till all bugs flying out 

best regards johan

Here is what worked for me after the Windows 10 2004 update made two of my computers run as slow as molasses.

(1) Boot in Safe Mode

(2) Delete everything in the Windows prefetch folder.  The folder is usually at C:\Windows\Prefetch

(3) Reboot

Windows rebuilds the prefetch folder so deleting it will not do any harm.  However, if you feel squeamish about deleting it, then rename it and create a new, empty prefetch folder in its place.

I spent hours on the first computer before stumbling onto this.  When the Windows update, and slowness, hit the second computer I tried this fix first and it immediately sped up.

Hopefully, it will help you.

Will try it. Thanks much

Windows isn't becoming slower. That's a misconception !

I'm a programmer and I had (and still have) Windows 10 from it's first release. I've gone through all the updates and versions and the system kept it's parameters without exceptions.

Now I've installed v 2004, It's a fresh install because lately I've done some experiments with my PC and .... you get the picture.

The system has the same speed, with a slightly noticeable "pause" when you start a program or app than the 1909.

If you're still running on HDD, please change it immediately with an SSD.

Two things I've always done, right after a fresh install or major update of Windows:

1. Stopped and disabled SysMain service, or SuperFetch how it was called in early versions.
2. Stopped and disabled indexing service.

As a professional, I've never understood the role of SuperFetch (SysMain), other than keeping my drive bussy all the time. And the indexing service is just lame. I mean, if I don't know to organize and label my stuff it's my problem. That's my point of view, anyway.

Right after stopping SysMain, you drive will breath again. Trust me on this one.

It does work for me but only for one day, following start up , boot time is back to 50 seconds. I am using western digital green ssd Ryzen 3 2200g with 16gb ram
