Windows 10 2004 Update Fails at 91%

[MisterWeather]

Greetings

In updating my 4 PC's - 3 laptops one Desktop - all failed loading the Windows 10 2004 update at 91% and reverted back to the 1909 feature enhancement. Two laptops are Lenovo, 1 laptop and the desktop HP.   Has this been observed by other users?

Removing Malwarebytes 4.1 allowed the 2004 Update to load without a hitch. I am now hesitant to install MBAB 4.1 back on any box until the issue is resolved. 

Sorry, but I have no log files to indicate the failure and was not thinking fast enough to even get a screenshot of the error. I see in other forums the "resolving host" error that I also had with the 1909 Feature Update

Thanks in advance for any assistance.

Hi,

Thanks for posting in the Malwarebytes for Windows Help forum.

Good morning,  @MRWeeden   

Sorry that you have encountered trouble.   Please be sure to run the Malwarebytes Support tool on each of your pc's  & attach those for review.

Look at details   above   ( under Advanced options).   Later on, if needed, I can guide you to getting the Malwarebytes 4.1.1 Beta.

Sorry for your trouble.   It may be due to possibly having a old BIOS  or perhaps some underlying infection.

I have been running the Windows 2004 build ( in different iterations) for months along with Malwarebytes 4.x

Post your reports & we will get you all squared away.

[Maurice Naggar]

Hi.   If possible,  also attach a copy of this log for review

C:\Windows\Inf\setupapi.dev.log

Sincerely,

Maurice

[MisterWeather]

Find attached 2 .log files related to the reboot

Also the mbst zip file

The smaller file is from the failed reboot, the larger file from the successful loading of Win 10 2004 after uninstalling MalwareBytes

Hi.   Thank you so much for the reports.  We can do one pc at a time.

I am glad to see this HP is on Windows 10 Pro Version 2004 19041.264 (X64)

I notice Windows Defender is the resident antivirus.    That is fine.

I notice Windows System Restore is disabled.    So lets get that Enabled.   Do the enable using this how to

https://www.tenforums.com/tutorials/99782-enable-disable-system-restore-windows.html

.

I am going to lead you on some other "precaution" measures, just in case.

Enable use of F8 function key   ( so if needed, you can get to Advanced boot menu in a pinch).   This helps if you ever get to some point where OS booting needs special help.

On the Windows taskbar ,  on the Windows search box,  type in

cmd.exe

and then look at the entire list of choices, and click on Run as Administrator.

 

It is best to  use COPY & Paste for the following.

At the prompt either type or copy/paste the following commands, tap  Enter-key after each command:

bcdedit /set {bootmgr} displaybootmenu yes

tap Enter-key when ready to proceed.   When done, close the Command window.

.

The next steps are to do a new setup of Malwarebytes for Windows and immediately to get that set for the beta version 4.1.1  which will do better on your machines.

Have patience when doing this.    The end result is worth the doing.

The Malwarebytes setup file is already on the Downloads folder.   We can use that.

If you start it and the Windows Smartscreen has a message about it,  we need to have you take these options:

click line *More info* information on that screen and click button *Run anyway* on next screen._ 

Click YES when prompted by Windows U A C prompt to allow it to run. 

Note: If you are prompted by Windows SmartScreen, click More info & followup & choose *Run anyway*. 

 

So locate mbsetup.exe  & do a Right-click on it and select Run as Administrator.   Keep the tip above in mind.

Follow the prompts in the Malwarebytes setup.

.

Once after this setup is done,  now we need to get the program onto version 4.1.1   with the latest updates.

 

Start Malwarebytes.

Click the settings  ( gear icon)  off the top right corner.

Then look at the tab "General".   Then scroll down to "Beta updates".

On that line,  click it so that the radio button is to the far right.

Next, scroll back up to the section "Application updates".

Look for the blue color "Check for Updates".   Click on that.   Watch for update messages,   Follow the prompts.

If the updates to the program for Component package 1.0.931  doe not show,  then at the Top of the next Clock hour,  then repeat the Check for updates.

You can view which program component & version of Malwarebytes by click the About tab.

If it has the very latest beta, it should show  version 4.1.1.71    and  component package 1.0.931

correct typo

I overlooked one extra final step    ( after you have done all above).

This is just to get Windows Defender antivirus to be the main resident antivirus.

There is one setting in Malwarebytes that needs to be off.     The Premium ( or trial ) protections of Malwarebytes will still be on.

Start Malwarebytes. Click Settings ( gear ) icon. Next, lets make real sure that Malwarebytes does NOT register with Windows Security Center 

Click the Security Tab. Scroll down to 

"Windows Security Center"

Click the selection to the left  for the line "Always register Malwarebytes in the Windows Security Center".

Close Malwarebytes when done.

Hello @MisterWeather    

How are things ?

I am stopping by to mention about "resolving hosts" situation with browser (s)   that you referred to in your first post.

For that,  you may want to check out this set of tips

Please note that we have released a new beta today that we hope should address the issue with Windows 10 build 2004

If you're running Windows 10 build 2004 and were having an issue please try the new beta and let us know if this beta version corrects the issue or not.

Thank you

The feature update 2004 fails at 91% on reboot. It happens in a PE situation, so how can any windows program interfere with the update?

[exile360]

If the Early Launch Anti-Malware (ELAM) driver for Malwarebytes is loaded, that could be the reason.  Likewise if the early start option for Malwarebytes' Self-Protection driver, though I don't know if either is loaded or is trying to load during that phase of the Windows Update install process.

Open Malwarebytes and turn off start with Windows and then exit MB from the system tray and try the upgrade to 2004 again.

I have seen the 91% issue 3 times already with clients.

 

 

[AdvancedSetup]

If you are booting from a USB or DVD drive to install the Windows 10 build 2004 then none of the current drivers are in memory and cannot prevent an install.

You may need to look at the logs
https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/windows-setup-log-files-and-event-logs

One thing I would try is running a disk check on the main hard drive.
