WVD Issue -Explorer Constantly Crashing and Restarting
Mark Aldridge Hi Mark, I'm seeing the same issue occur every now and then. It's caused by the Windows Search service. If you restart this service the issue stops (you don't need to restart the host and you can restart the service with everyone else logged on).
I've had to created a scheduled task to restart this service at logon. Far from ideal though. I assume it's yet another bug in Win10 2004...
On top of a major bug in FSLogix (which breaks OneDrive Files on-Demand) I'm getting pretty fed up with Microsoft right now.
This specific issue only impacts Windows 10 Enterprise/multi-session version 2004 and the fix is currently scheduled for release in the third week of October.
In that third week of October - if you manually click the “Check for Updates” button you will get it. If you won't check manually, you’ll receive this bugfix in November's Patch Tuesday (second week of the month).
Hi Pieter - Case # 2102180010003574. I am suspecting the FSLogix is what causing explorer.exe to crash but it's not definitive because this is a random issue. Microsoft performance team was not able to fine the root cause. For now, I disabled FSLogix via Registry entry because most people access our WVD environment to run certain applications.
Thank you,
Tz_Blog it's hard to troubleshoot these issues over forum posts, it typically requires a memory dump of the app or sometimes the full OS before being able to point to the root cause. This thread has been around an issue that was fixed in November '20 - also the last time someone replied to it.
It's not unlikely the issue you are having is something completely else. Do you have a CSS case number I can look into?
Hi Pieter - I still have this issue after multiple attempt to work with Windows Performance Tech Support. From this forum, it sounds like a major bug that aren't being addressed yet.
- The host that is not in production does not have any windows deferal settings configured in Domain Group Policy. Before they move into production WUfB policies are defined. I have just checked a pre-production and its local group policy no settings are configured. In your screenshot there is even a hold date configured so something historically must have set it. Maybe run rsop.msc on the server to see what GPO that is coming from if it is.
Dale Hayter Thanks for the swift reply fella, do you have any hosts in production? I ask as I see it on the 2004 host, which are still in dev but also on the production 1909 hosts as well, I am just trying to work out when it was set, it is not something I have gone in and implicitly set, and there is no reference to that local GPO in any of the optimise/finalise scripts I run so wondering if it is turned on by default??
Adam.
Adam1970 Nope. This particular farm we haven't deferred any updates as not in production yet. At least you know why you are not getting the update...
Dale Hayter Hi Dale, so all the hosts I have checked both 1909 and 2004 have the attached policy set, which has a 30 day deferral for any quality updates, it is a local policy and not something I have set, I wondered if the optimise script I use could have set it but I cannot find any reference to it, so I was wondering if it was a default policy set for the multi session image used for WVD?? Did you have it set??
Thanks in advance
Adam.Dale Hayter Hi Dale, yeah it looks like we have there is a local GPO set for it, no idea where is has come from though as I did not set it and there is no domain GPO set, thanks for the heads up though mate 🙂
Kind regards
Adam.
Adam1970 It appeared on one of our WVD farms ok. You dont have any deferral periods defined for quality updates do you?
PieterWigleven Hi Pieter, the 10c update never showed so I did a manual install, hopefully this will resolve the issue with Windows Explorer restarting, I will let you know on here if not, many thanks for your help.
Kind regards
Adam.
Adam1970 any luck? Curious to hear if you managed to find the update and seeing any changes.
Adam1970 I'm not sure why the 10C update isn't offered, it should be once you're up-to-date and you manually go hit the update button. You can also download it manually by going to the Microsoft Update Catalog and search for it (direct link here).
You may need to download the Windows Server version due to the way win10 multi-session identifies itself.
Hope to hear from you whether this helped.
PieterWigleven Hi Pieter, I am still not seeing it, there were some updates as you can see from the image I have uploaded, however after installing those and restarting it is now showing as "You're up to date" Any other ideas??
Cheers
AdamAdam1970 I'm seeing it on one of my test VMs (see attached screenshot). Please let me now whether you are able to see this in the Windows Update settings page.
PieterWigleven Hi Pieter, I am still not seeing it, am I missing something??
Cheers Adam.
Adam1970 Hi Adam, I've been chasing this internally and it turns out the 10C release has been delayed for Windows 2004/20H2 to 10/29/20 - in other words: tomorrow.
Let me know if you are able to see it come down and hopefully remediates the issue you are experiencing.
Thanks,
Pieter
PieterWigleven Hi Pieter, I am still not seeing this update, it is preventing me from completing work I need to, it was supposed to be released last week, can you please check what is going on??
Kind regards
Adam
Adam1970 Hi Adam, should be this week - not sure which day exactly. It will require to check for updates manually, see if anything (other than AV definitions) is being pulled down.
PieterWigleven Hi Peter, do we have an actual date on the release of the fix?? Or can you update this forum when it has been released so we know??
CheersAdam
