Pinning and unpinning Start menu items on Windows 11 Server 2025 via command line? Yes!
Still very early stage - but it’s working 😎

Working on a new project: TaskbarPin – Command-line tool to manage your Windows 11 taskbar pins. Pin by app name, index, or exe path, at any position. Unpin, reorder, and export/import layouts across machines. Works with Win32, MSIX, and UWP apps on Windows 11 😎

New UCPD.sys pattern update now blocks mshta.exe. I’ve used this workaround since May 2024. It looks like the .hta trick (or inline scripts) got abused in the wild and is now blocked. Yes, this affects the personal edition of SetUserFTA - on consumer Windows.

UCPD.sys dynamic rules are now live. They’re shipped in a non-executable PE with multiple signature checks and an encrypted payload. I’ve decrypted it – currently it just extends the deny list with a single new entry.

Looks like Microsoft is now A/B testing the UserChoiceLatest hash on Windows 11 Enterprise. It's 2025 - and it takes 5,000 lines of C just to change a file type association.

More technical details: the PE file they are referring to is not executed. Instead, it is used to dynamically update the driver’s functionality, similar to a signature file.: min.news/en/news/6d1f017397d…

Chinese researchers allege #Microsoft’s Windows hides a “backdoor” via UCPD.sys: blocking Tencent, 360 apps but letting foreign rivals pass, logging Chinese IPs in detail, and enabling remote code execution. EU forced openness under DMA; in China it raises privacy & security alarm.

Microsoft is now enabling almost all the new features I covered in my blog on Windows 11 Pro. My test VM has most of them activated already - interestingly, file rename protection isn’t active yet.

UCPD.sys v4.3 is now rolling out on Windows 11. It brings 6 new protection features (currently inactive) - including one that blocks the file renaming attack 😬

Looks like Microsoft is rolling out the new hash protection more broadly - even my test VM just got migrated to UserChoiceLatest. Time to update @SetUserFTA, I guess 😬
