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.
I found another "trick" to solve the isue : https://answers.microsoft.com/en-us/windows/forum/windows\_10-performance/computer-stuttering-after-windows-10-update/06a41353-13cb-4767-bd4a-06c957a35374?messageId=404371ee-bcc4-45bf-8612-5f0b133422d0
Disabling my cd rom reader via the right click on "windows" / device manager / disable device for the CD ROM reader immediately stops the stutter.
Re enabling the cd reader is not creating the stutter again.
I just wanted to add, I cant try disabling the CD/DVD drive as I dont have one on my PC.
