Microsoft says that it is working on a fix but, for now, has provided a couple of workarounds to deal with the issue. First, Microsoft says that restarting the Shell Infrastructure host (SIHost.exe) service will help restore the missing Immersive Shell packages. This can be done with the following commands:

Add-AppxPackage -Register -Path 'C:\Windows\SystemApps\MicrosoftWindows.Client.CBS_cw5n1h2txyewy\appxmanifest.xml' -DisableDevelopmentMode  
Add-AppxPackage -Register -Path 'C:\Windows\SystemApps\Microsoft.UI.Xaml.CBS_8wekyb3d8bbwe\appxmanifest.xml' -DisableDevelopmentMode  
Add-AppxPackage -Register -Path 'C:\Windows\SystemApps\MicrosoftWindows.Client.Core_cw5n1h2txyewy\appxmanifest.xml' -DisableDevelopmentMode  

Second, a PowerShell logon script has been shared that essentially blocks Explorer from launching prematurely until the required packages are fully provisioned. The batch script for that is given below:

@echo off  
REM Register MicrosoftWindows.Client.CBS  
powershell.exe -ExecutionPolicy Bypass -Command "Add-AppxPackage -Register -Path 'C:\Windows\SystemApps\MicrosoftWindows.Client.CBS_cw5n1h2txyewy\appxmanifest.xml' -DisableDevelopmentMode"
REM Register Microsoft.UI.Xaml.CBS  
powershell.exe -ExecutionPolicy Bypass -Command "Add-AppxPackage -Register -Path 'C:\Windows\SystemApps\Microsoft.UI.Xaml.CBS_8wekyb3d8bbwe\appxmanifest.xml' -DisableDevelopmentMode"  
REM Register MicrosoftWindows.Client.Core  
powershell.exe -ExecutionPolicy Bypass -Command "Add-AppxPackage -Register -Path 'C:\Windows\SystemApps\MicrosoftWindows.Client.Core_cw5n1h2txyewy\appxmanifest.xml' -DisableDevelopmentMode"  

I swear to god, if I hear "Windows just works" one more goddamn time...

What kind of idiots create a program that says, "Outlook failed to load. Repair application?" when the only problem is the wifi is disconnected?

Why does File Explorer freeze just because I opened it?!?

Every time???

How do they mess this up so bad?

Install Linux.

Ah but there are also a lot of minor features in Windows 11 that aren't really looking too good.

My decision to switch to Linux feels better and better every day. Windows 11 sucks.

Some anecdotal evidence, but when I boot into my W11 install for certain online games, I have none of these issues mentioned. My 11 IoT Enterprise LTSC + StartAllBack setup- knocks on wood- continues to be bullet proof. For anyone who still needs Windows, I highly recommend it.

When do I get a calendar on my systray or whatever they call it on my other monitor?

I use windows 11 everyday, without issue. what exactly is broken?

We have finally gotten rid of Windows on all PCs in our house this week and my partner has taken the plunge. Even with a little faff he says he is never going back lol.

Man, I have 3 windows 11 desktops and a laptop. Sometime in the last month all of their edge browsers became “managed by my organization”… they’re all personal computers with no work info on them. And I can’t undo it. I’ve tried every trick on the internet. Fuck MS.

They're contributing to making the world a better place by increasing Linux adoption. Thank you anonymous Microsoft vibe coders and overly enthusiastic PMs.

You know I never really thought about it but do you think the spying tools these companies provide ever fail like the way their other products do?

They could resolve many things if they did not push AI so hard, or making stupid things like removing the local account option, windows recall, etc.., but i guess SHAREHOLDERS.

That’s quite a headline they’ve got there!

After provisioning a PC with a Windows 11, version 24H2 monthly cumulative update released on or after July 2025 [KB5062553], various apps such as StartMenuExperiencehost, Search, SystemSettings, Taskbar or Explorer might experience difficulties.

This will occur for the following: First time user logon after a cumulative update was applied. All user logons to a non-persistent OS installation such as a virtual desktop infrastructure (VDI) or equivalent as application packages must be installed each logon in such scenarios.

If you are wondering, provisioning essentially is the way admins configure devices as they automatically deploy various settings and policies on a client PC. So while the issue is in office PCs, considering a huge number of enterprise PCs are Windows, this is probably a very big problem.

IT has been an interesting ride the last two months, encountering some of the weirdest bugs I've ever seen, after two decades of Windows working just fine for the most part.
