new Z2 G9 system, windows 11 freezes throughout the day

[Gwandoya]

I've also uninstalled all HP software, but the Windows Services I listed earlier remain and appear to be installed (and periodically re-enabled, set to Automatic) without any user interaction, possibly via Windows Update since a lot of OEM stuff is delivered that way these days.

Run services.msc from the command line and check if any of these Services are Running and set to Automatic:

• HP Analytics service
• HP App Helper HSA Service
• HP Diagnostics HSA Service
• HP DSU LAN/WLAN/WWAN Switching Service
• HP DSU Service
• HP Network HSA Service
• HP Services Scan
• HP SFU Service
• HP System Info HSA Service

If so, Stop and set each Service to Disabled. That's all I've found that works.

I signed up JUST to comment on this issue.  My Z2 has the same issue.  Just disabled all the HP services.  If this works I owe someone a beer/hug!  LOL

An update from me. When I have the freezes often it will bring File Explorer Windows to the front of the desktop and Outlook will have some minor changes in its UI. It is like focus is change in the windows just like when you press them.

HP had autoinstalled some services which I again disabed recently. I have now removed the scheduled tasks it generated and also I am removing hp support assistant from my machine.

Keep in mind, if I reboot things will seem fine until the machine has been powered on for about 1 day then problems start appearing again. If you do not use your machine for that long or if you restart often, it might seem like the issue is gone, but its not.

Also, I have a colleague who got rid of the issue completely only to have it return again. Maybe due to HP services returning, so he disabled them again. The saga continues.

Lars...I just realized that mine was doing the exact same thing with the Explorer Window too.  Stopping AND disabling all the HP services has seemed to have fixed these issues.

@JJP18018

Stopping and disabling services did nothing for me at all. I have my PC on for days in a row though it does do more aggressive updates now.

Are you sure yours is on for 1-2 days when you evaluate if it is solved or not?

There is a software "DPC Latency Checker". If I run that, it will start fast and easy when I just rebooted by PC, but when the problem evolves and starts up, starting that software will become choppy with the mouse curser and also take much longer. From being instant it becomes 5 seconds. I think the issue is not that its either there or not, I think its there all the time but starts small and becomes progressively worse the long the PC stays turned on.

What software are you running, is this for games and do you have a gaming vid card or is this a work PC? This could be a driver on a gaming card etc.

Also, have you tried disabling all power saving settings in both windows and the bios?

On my end I use this as a work PC but I do shutdown every day. The issue rarely surfaces and when it does I just disable the hp services again.

Lars...I had my PC on all day since disabling the services.  Not once did it freeze or pop up the random Explorer window.  It had be constantly doing that BEFORE I tried the services.  PC is normally up and running 24/7 as I never shut it down.

@Wthe 

Its basically a mint PC with intel integrated graphics. There is nothing custom to it at all.

I am running Windows 11 Enterprise installed from a Microsoft image, all drivers installed are installed by HP Support Assistant.

All power options I can find in bios are disabled and screen buffer RAM increased. Also disabled some of the management engines stuff in there.

Windows runs in ultimate power mode, and I manually went through all settings to turn anything on that might indicated power saving or otherwise fancy handling of hardware states.

If you shut down the PC every day you are unlikely to see the issue. If I restart my machine it takes about a day before the slow downs become noticeable. So if you want to know you are clear of it then it has to run for longer. Maybe the HP services will make it appear faster though than 24 hours, it was just some of the first stuff I disabled so I never noticed much there.

Btw, we bought 2 of these PCs with that config, both had more or less the same manual install (no company PXE image or anything). Both have the same issue. We do share a lot of configuration also, OneDrive, some security software, remote desktop apps and have the same GPOs applied from the domain. Given that the issue is experienced by many others it might be some of these things that are custom to us, but it will be hard to know without sharing system configuration which I cannot do due to the kind of work I do.

Glad to hear you seem to be rid of it, I hope it stays that way  and thanks for the elaboration 🙂

I hope that you get yours fixed too.  It's darn frustrating...isn't it??
