I made a little demo for revealing an image behind some mouse movement! I think it could be a cool web component but I'm too lazy to do that right now.

Mouse reveal image
Either move your mouse around or click to reveal what's in the blurred image!...

My GitHub repo summarizes different learning resources about Windows Internals. github.com/patrickmatul...

If you're missing a course or something that feels "course-like", let me know and I'll add it.

What do you think about WinAPI monitoring in ProcMon as a new feature?
I posted the suggestion in the official LinkedIn Sysinternals group: www.linkedin.com/feed/update/...

Interesting memory dump analysis in WinDbg. I think it's very useful not to show only the "golden path" to the solution!
It turns out this analysis was incorrect, and someone pointed it out to me. I've redone the analysis, and it's now much improved. For Part 2, where I cover the true cause of the crash, please take a look here: medium.com/@Debugger/un...

OST2 is an amazing (and free!) platform for learning.
🙌We're happy to announce OST2 now has over 31k students registered! 🥳 By the time we noticed we crossed the 30k mark, we were already at 30.5, so we figured we'd wait for 31k, which is now!🎉

👏Kudos to all the students taking and finishing classes!👏

next goal: 12 hour stream :D
Yesterday we did a 7+ hour stream on AspiriFridays where we took excalidraw and made it work with aspire.

This is also the first time we have chapters in any episode! (thanks @maddymontaquila.net!).

In the end, we got it working!

After so many posts about Sysinternals, you may be interested in learning more about the Sysinternals Suite. The official reference is the book "Troubleshooting with the Windows Sysinternals Tools" written by @markrussinovich.bsky.social and Aaron Margosis.

It's possible to explore the stack of specific threads in Process Explorer. Unfortunately, the stack will not resolve properly without some modifications. Usually, you need to install the Debugging Tools for Windows (from the Windows SDK) and set the DbgHelp.dll path correctly.

You probably know about Autoruns. It's a great tool for analyzing startup apps from different sources. But do you also know the CLI version? It's called AutorunsC — great for exporting or piping the output, but you can't disable or delete entries with it. #sysinternals

Why would lsass.exe consume an entire core of CPU time for minutes at a time? An ETW trace shows that it is spending its time in efscore.dll!EfspGetUserDecryptionKeyForHash. Inside that it spends most of its time opening/closing files in AppData\Roaming\Microsoft\SystemCertificates\My\Certificates

During your troubleshooting adventure, it's common that you want to filter to all write access. That's very easy with Process Monitor. You can just filter to Category is Write. That will work for file and registry activities.

I'm not sure how I missed this article on Entra Kerberos, but it's the most comprehensive documentation I've seen yet, absolutely fantastic

If this is the "Introduction to Microsoft Entra Kerberos", I'm honestly a little scared to see the deep dive 🫣😅

Sysinternals jcd (jump change directory) is a Rust-based command-line tool that provides enhanced directory navigation with substring matching and smart selection. It's like the cd command, but with superpowers!
