Computer "stutters" after Windows 10 update (20H2 update 19042.868)

Hello 

I face again an issue  on my desktop since Windows 10 20H2 update. Stuttering twice per second : mouse move is blocked for an instant, video and sound stutter constantly. Computer not usable anymore except for basic functions.  

I tried many things , including updating drivers , removing almost all old software, clean restart etc... following advices from other threads. Task manager "processus" tab shows it comes from high level of  "system interrupt" ("Interruptions systeme" in French) .I could not determine the root cause. 

 Note also  stutter disappear completely after rollback to Windows 10 previous version. However staying in previous Windows 10 version is not sustainable : we are currently forced to update .

Note that stutters is still present after safe boot restart. 

Eventually I got rid of the stutter temporarily (comes again every few minutes instead of twice per second)  after a SAFE BOOT restart (msconfig / start)  followed immediately by a NORMAL RESTART . I do not dare to restart normally again, so I use the "sleep" (mise en veille in French) mode at night to keep it workable. 

PLEASE MICROSOFT do your upmost to deliver fix ! Do you have another suggestion ? 

Best regards to all

Hi,

I found the same problem right after the update KB4589212.  Not sure if this is the sole source of the issue. In any event, I disabled the CD/DVD drive and the problem disappeared. Re-enable CD/DVD still working - this happened more than once - as I purged the system trying to find the hiccup.   Also noted a marked slow down of the system - editing e-mail...writing this note, etc...

Kind regards,

DBN

Hey Druid,

I created an account just to thank you.

After I updated to 20H2, my company has been stuttering non stop and cant even do the bare minimum stuff without feeling frustrated.
Went through weeks of guide and advice on how to solve it but it did not work.  Until I chance upon your answer. I was like thinking, how can a CD/DVD drive be affecting the whole computer, i was like what the hell what do i have to lose. the instant I disabled the drive, the whole com was back to normal. 

Thank you so much! I was almost contemplating to do a fresh boot or even purchasing a new computer.

Regards.

    After fighting 4 times with this 20H2 update i had it pin pointed up to the fact that the ataport.sys driver was causing Delayed Procedure Call Latency (checked thanks to LatencyMon)

    Simple way to reproduce the hard slowdown was to open explorer.exe directly to "This PC" (not to quick links) while playing some sound.  You could then hear the chaotic way your computer was slowed down.

    Reading you telling to disable the DVD rom made sense since that driver is used by the dvd rom .. and since i have no use for it anyway .. i went and disabled it ... and magic happened..  Thanks a lot for the tip man .. i was going crazy disabling windows update service everyday ><

    btw: i red many other posts leading up to here, all related to Asus Z87 variants of motherboards , pro, plus, expert, deluxe.

    Thanks again :) i can finally use my pc normally

    Hi,

    Thank you for the reply - greatly appreciated. 

    Ran SFC - errors found & corrected 

    Ran DSIM - all OK 

    Ran memory test - all ok 

    Reboot - problem returned 

    Ran SFC - no errors 

    Disabled CD/DVD - problem disappears 

    The same scenario above found when I reinstalled Windows 10 trying to hunt-down the issue. 

    Overall system performance decreased significantly after update(s) - not 100% sure which one but the system is running latest Windows 10 

    Kind regards,

    DBN
