Computer freezes when I open task manager.

Today for the firs time it's showing up at client sites. On the plus side, at least I don't need to waste a lot of time debugging it, but even average users are used to opening up task manager if a program hangs. So it's not practical to tell them not to use task manager. 

Ah ok!

Nah I feel the same, I don't really wanna tell my end-users that they need a third-party program to "get around" the problem.

This should not be needed in a practical matter. Even if it's a working solution for the time being.

Go, go Microsoft! I actually downgraded myself to 1703 yesterday and my own workstation is feeling so much better overall. Blocked 1709 for 80days for the moment.

I've received suggestions from Microsoft Support to use the Feedback Hub to provide feedback on this issue by replicating it with the "Collect Diagnostics" option running.  However, like stated before...the computer freezes, so there's no way to submit the feedback.  The system locks before I can.

Funny enough, I was talking with another person in IT yesterday and mentioned my frustration with this bug and he said that he's had the issue as well and just moved to using Process Explorer.

I'm beginning to think this issue is a lot more prevalent than the limited number of people here reporting it would make it seem.  Many just look for alternate solutions, likely because they're tired of the same suggestions for every issues....  SFC, DISM, Refresh, Reinstall.  You'd think with all the telemetry data that MSFT collects by default, they'd see the problem if they'd just look.

Fingers crossed that the 3/18 maybe called "Spring Creators Update" provides some resolution to this.....

Yeah it sucks.

They cant tell me what to do to fix it, and really don't think they care.

If you read above which it sounds like you did, not one of those things work.

Microsoft tech support needs to contact us directly, and fix this issue.

Exactly. Posting here was sort of out of desperation once I realized this was happening on more computers. I'm an IT pro that works these kinds of issues day in and day out. This has actually been going on for months on one computer, but just worked around it and didn't use task manager. Figured sooner or later a patch would get released to fix it. Now that it seems to have spread I can no longer ignore it. I really don't know what more I can do other than the typical SFC / clean boot / reset Windows. 

Same here... this is bad. Also IT tech here and working with different clients everyday. Reading this thread just makes you irritated even more. Please Microsoft! The normal "do a clean boot" doesn't suffice. This is clearly a big BUG in 1709 that needs a solution.

I've ducked for this for a while but as you said willp2 this can't be ignored anymore. I've been in a similar thread at Spiceworks community and it's the same "mumbojumbo" there too, no answers just **** about repair that, do a clean install. NO. This is a major problem and please Microsoft prioritize this.

Releasing amounts of new builds that's not even working properly is a bad business.
