The whole network is having computer freezing issues, black screen and network drop issues.

Question

Hi,

I'm slowly losing the plot...wandering if someone can help.

I had a nice stable network of 50 odd PC's after upgrading all of the desktops to HP 600 Mini G6 and laptops HP Elitebook 840 G7.

I decided to enable Windows Updates for all of the network, this caused a both laptops and desktops to start freezing.

I have got down to booting the PC's with only Microsoft services using MSConfig, no AV, cut down performance options.

This is mostly working, still getting random black screen flickers with a network drop out.

The small network drop out breaks 3CX and Magic XPS.

Also have a fun issue if Snip & Sketch also freezing some users or at least making them pause for a second.

I've run through sfc /scan, all the DISM rebuilds and checks, my own laptop does not have this issue...

There are no Event log errors, I spoken to HP who said to talk to MS.

I have spoken to MS, but only asked me to run MS Config and remove anything none MS.

All computers are built exactly the same, same software, same specs, some have problems, some don't.

Memory Dumps are useless because there are no event log errors, so reliability monitors just says that the PC was forced restarted.

All Windows Updates have been installed, all driver updates have been installed, all firmware updates have been installed.

I used to be able to restore the devices back to before I started Windows Updates, but now even that doesn't fix it...

Help?

Thanks...

Are all of those PCs / Laptops under the active directory domain?

Hello @Lee Howard ,

If the problem started after enabling the windows update, you can disable this update via Gpedit.msc and check if the problem persists or not, to do this just follow the steps below:

1) Press Windows logo key + R, type gpedit.msc and click OK.

2) Go to “Computer Configuration” > “Administrative Templates” > “Windows Components” > “Windows Update”.
Double-click "Configure Automatic Updates."

3) Select “Disabled” under Automatic Updates configured on the left and click Apply and “OK” to disable the Windows automatic update feature.

You mentioned that all updates are installed, I believe you verified this by Windows Update, but it is always recommended to check the version and Build of windows 10 to know if it really is in the latest version or Build, to do this just follow the instruction below:

To check the Version or Build: Press the Windows key + R and type: winver and press Enter

If one of these versions appears: 1903, 1909, 2004 or 20h2, it means that your windows is not in the recent version.

For you to update to recent version you can follow the instruction below:

https://www.microsoft.com/en-us/software-download/windows10

Step 1: Access the above link and select the Update Now option, an application will be downloaded in which you must install on your computer.

Step 2: when installing you must open the application and the download, verification and installation of the recent version will start.

Step 3: After you will be asked to restart the device to complete the update, after a few minutes you will have the latest version.

Hi Md, Samuel

Yes the workstations are on the Domain.

I have disabled Windows Updates (using Group Policy), all of the PC's are 20H2 before I started to update to 21H1. I stopped updating them as I wasn't sure if that was causing the problem.

Thanks for your input :)
