Microsoft recently acknowledged reports of two critical bugs in
Windows 11 –
Blue Screen of Death and app crashes. These two bugs were
originally discovered in November 2021 Patch Tuesday and
currently affects some installations of Windows 11 as well as
the latest versions of Windows 10.

On the original known issues page, Microsoft officials
explained that a bug in Windows 11’s recent updates can result
in Microsoft Installer (MSI) failures. Microsoft’s findings
suggest apps that are known to be affected include security
solutions from Kaspersky. If your device is affected, some apps
might fail to open.

Apps crashes are experienced only when you apply an update to
the affected app or try to repair it using Windows Settings or
Troubleshooter. Microsoft previously stated that they’re
working on a fix and recommends users to reinstall their apps
if the apps are crashing without error messages.

Thankfully, Microsoft has now developed a new fix which is
rolling out to testers in the Beta and Release Preview Channel
as part of Windows 11 Build 22000.348 (KB5007262).

According to the release notes, this patch contains a fix for
an issue that might prevent apps from opening after users
update or repair them using the Microsoft Installer (MSI).

The fix is currently available to testers only, but it should
be published in the production channel as part of the next
optional update.

Other fixes coming with a new optional update for Windows 11

We’re expecting the new optional update for Windows 11 in a few
days. Remember that there’ll be no new features in that
optional update, but you can expect fixes for several other
issues reported over the past few weeks.

For example, Microsoft fixed an issue that affects PowerShell
7.1 and later. As per the tech firm, a bug could break Appx
PowerShell cmdlet functionality for some users and it will be
fixed in the next update. Additionally, a bug where some users
see a “bad image” error at startup is getting a fix.

Microsoft has patched an issue that
crashes searchindexer.exe or causes high memory usage. It
is typically experienced on devices where a dismount is in
operation in the remote desktop environment.

Likewise, you can expect a fix for an issue where devices stop
responding when they return from sleep or hibernation. This has
been reported on devices with certain processors only, but
Microsoft has yet to publish the list of affected CPUs.
