2026-07 Security Update (KB5101650) (26200.8875)

Cheron S 45

I have Windows 11 Pro and 2026-07 Security Update (KB5101650) (26200.8875) continues to fail to update. Is there an easy fix that doesn't require me to change settings to make it go through?

Please see if you can install the latest cumulative update offline. Here are the instructions:

Create a folder named Packages at the root of the C drive. (i.e., C:\Packages)

Download the following .MSU files from Microsoft:

https://catalog.sf.dl.delivery.mp.microsoft.com/filestreamingservice/files/07dceb13-ffad-47c5-a8fe-0f195bd14dc9/public/windows11.0-kb5101650-x64_5d4163c2e483adc9456b7ea9a8ea83d8fceaf52c.msu

https://catalog.sf.dl.delivery.mp.microsoft.com/filestreamingservice/files/d8b7f92b-bd35-4b4c-96e5-46ce984b31e0/public/windows11.0-kb5043080-x64_953449672073f8fb99badb4cc6d5d7849b9c83e8.msu

Copy the above .MSU files to the C:\Packages folder.

Open Command Prompt (admin) and run this command:

DISM /Online /Add-Package /PackagePath:C:\Packages\windows11.0-kb5101650-x64_5d4163c2e483adc9456b7ea9a8ea83d8fceaf52c.msu

(If it reports an error, please post a screenshot.)

Restart Windows when prompted.

Nothing seems to be working. Any thoughts on why the 0x80070005 error

0x80070005 means "Access is denied". It's usually caused by 3rd party antivirus, but there may be other causes.

Please share a zipped copy of the following setup log file on OneDrive (or any other host) and post the link here:

C:\$WINDOWS.~BT\Sources\Panther\setupact.log

Note: C:\$WINDOWS.~BT is a hidden folder. To access it, press Win + R, type C:\$WINDOWS.~BT and click OK.

Delete the C:\$WINDOWS.~BT and C:\$WINDOWS.~WS folders.

Uninstall 3rd-party antivirus if installed.

Restart Windows and try the Reinstall Now option again.

Those folders do not exist and I do not have any 3rd party antivirus.

Just curious, any ideas why this so difficult on this machine. I have 2 other machines (laptop and another PC) and don't experience this issue.

Clean boot Windows using msconfig.exe. A clean boot is the process of starting Windows without loading any third-party applications or services.

Launch msconfig.exe and select the Services tab.

Enable the Hide all Microsoft services checkbox. This is an important step. (Now, the list will contain only 3rd party services.)

Click Disable all.

Click OK. -Open Task Manager (Ctrl + Shift + Esc) and click on the Startup tab. Disable all startup apps.

Restart Windows.

Try the Reinstall Now option again.

When I run DISM.exe /Online /Cleanup-image /Restorehealth in Command prompt as administrator I get access denied. I am not able to Run SFC and DISM. Any other suggestions? Please not this is my personal PC and I have full administrative rights to run whatsoever. I've tried these steps before and get hung up trying to figure out why it is denying access.

I also get this message The DISM log file can be found at C:\WINDOWS\Logs\DISM\dism.log

Answer 2

Hi, good day!

Before suggesting more advanced troubleshooting, could you answer a few questions?

What error code do you see? (For example, 0x800f0922, 0x80070002, etc.)
At what point does the update fail?

While downloading?
While installing (for example, at 20%, 35%, or 100%)?
After restarting, when Windows says it's undoing changes?

I look forward to your update and am willing to collaborate with you until we resolve the issue. Keep me posted by clicking "Add comments" below.

Install error - 0x80070005 is the error code that appears during installation. It downloads just fine but fails to install. I didn't catch the percent it gets to before throwing the error. When I do I plan to post it.
