Windows 11 June 2026 update, which was supposed to make PCs faster, is crashing some PCs with BSODs, breaking OneDrive integration in File Explorer and custom folder icons, and causing other problems.
We're seeing reports that Windows 11 KB5094126 is causing boot failures on some PCs, mostly HP enterprise hardware.
The worst reports involve BitLocker recovery loops, Black Screen of Death/BSOD failures, Secure Boot signature errors, and error 0xc0430001.
Affected models appear to include HP EliteBook 840 G10, HP ProBook 460 G11, HP Engage One Pro G2 AiO POS, HP ZBook, and some Dell Precision systems.
The likely trigger is Secure Boot certificate handling + EFI partition space. On older images with a 100MB EFI partition, Windows may fail to update Boot Manager because there isn’t enough space, especially on HP systems where firmware recovery files can bloat EFI.
There are also File Explorer cloud integration issues. OneDrive, and in some cases Dropbox or iCloud Drive, may stop opening from the sidebar/tray shortcut after KB5094126.
Microsoft also confirms desktop.ini hardening can break custom folder icons or localized folder names from untrusted sources.
KB5094126 is important, as it fixes 200+ security bugs, but be careful, as it could cause havoc on some PCs.
@vishal_rayansec@AlteredSecurity I actually took CARTE directly without doing CARTP since I already had a solid background in Azure security.
So I can’t compare them side by side, but CARTE is quite hands-on and focused on real attack paths.
Good luck with your CARTP, hope you crush it 💪
Not every learning journey is smooth.
While preparing for CARTE, I hit roadblocks, confusing attack paths, and things that just didn’t click at first.
That’s what made it valuable.
Happy to have passed the Certified Azure Red Team Expert exam
Thanks @AlteredSecurity

Am I missing something here?
The Windows App is consuming around 10GB of RAM while I’m only running one Windows 365 Cloud PC.
This seems unusually high any idea what could be causing this?
We're shipping a new feature in Claude Cowork as a research preview that I'm excited about: Dispatch!
One persistent conversation with Claude that runs on your computer. Message it from your phone. Come back to finished work.
To try it out, download Claude Desktop, then pair your phone.
@adahstwt It's mostly a myth with modern power management, it pulls power directly from the outlet instead of the battery. I've used my early 2015 MBP this way for years in 2026, I still get 5 hours of battery life for Netflix and light tasks!
Claude can now build interactive charts and diagrams, directly in the chat.
Available today in beta on all plans, including free.
