Win Update KB5086672 Windows 11 Out-of-band Update build 26100.8117 (24H2) and 26200.8117 (25H2) - March 31

Ghot · Mar 31, 2026

MS is losing it. LOL
I think I'll pass on this one.
I dun need no artifishul intelligents.

FrancoDT · Mar 31, 2026

Went smoothly although I had no issue on either machine that had 26200.8116 either.

Mark K · Mar 31, 2026

I found my Windows 11 systems installing this update (KB5086672):

After reading the Improvements about this update, I guess it just re-installs or installs all the previous 3 updates.

I hope my laptops do not lock up from this update. Installed the update and I hope it is good.

<sarcasm>
I reported the problems through Feedback Hub, never got a response. I bet Microsoft listened to my words in their head while reading it, but nothing back.

So I'm in the process of getting this on both of my primary machines and have noticed that it doesn't seem to be all that substantial considering the install time.

Josey Wales · Mar 31, 2026

I just got 26200.8116 fixed and they send a new one.

After installing this update, the Dell Inspiron 15 3520 laptop is no longer booting. When I turn on the laptop, I just receive the Dell Support Assist window and it runs a hardware scan. The hardware scan comes back with "Success, No bootable device were found! Possible cause could be a corrupt OS or a boot device is not enabled in the BIOS".

I just got done installing Windows 11 Pro back on this system and it has been running without any hardware problems. This is my backup laptop.

I remember a solution I found with older laptops when it no longer boots.

I went into the BIOS to delete all the keys in Key Management. I restarted the laptop and it boots up now.

On my main Dell laptop, SFC finishes in ERROR. Not sure about this error right now.

DISM stops at 62.3% and hangs. I restarted Windows 11, ran DISM again, same problem.

DISM stops there while it does repairs. Depending on how big and how many errors that can take a long time at 62.3%. You'll have to be patient and wait it out.

Unfortunately I have some work that I need to get done and could not wait. There were a few more errors when Windows 11 restarted. I gave up and did hte usual monthly ritual after updates installed. I start over with reinstalling Windows 11. I don't have time to wait. Other times I would leave it run. This has been a regular occurring process for the past year.

Might want to try this next time... Use Option Two (ISO method)

Repair Install Windows 11 with an In-place Upgrade

This tutorial will show you how to do a repair install of Windows 11 by performing an in-place upgrade without losing anything. If you need to repair or create a new recovery partition or having problems with the Windows 11 operating system on your PC, and the usual solutions will not fix it...

You can keep all your Programs, files and drivers.
The In-Place upgrade, just fixes Windows itself.

I thought about doing it that way, including the Windows Repair option, but I wanted to make sure Windows 11 Pro is clean of errors. That is why I just reinstall to make sure everything is right. I don't have to restore any data because I save all my data on an external NVME drive. I don't trust Windows (for some time now) to have my data on the OS drive. Too many times OneDrive sync's it to the cloud and I don't use OneDrive.

I didn't have any problem with previous update and not having problems with this.
