Ok, @citrix really? First of all, Intune has been able to do this for years. So, you've figured that out, and you've even got a working template? Oh, wait a minute - your new ADMX doesn't work too, because you forgot to include EXPLAIN strings in 2 spots. github.com/MHimken/FixMyAdmx

Replying to @NetScaler
@NetScaler now supports (hybrid) Post-Quantum Cryptography (PQC) which will be soon NIST's new default. I also did some tests by configuring PQC and connecting with the X25519MLKEM768 key exchange. julianjakob.com/netscaler-te…

PSAppDeployToolkit 4.1.0 is out. PSADT 4.1 is a release that fixes all reported bugs from 4.0.x and includes major improvements such as eliminating the need to use ServiceUI ever again. If you are still on PSADT V3, then this is the time to switch. Master Wrapper is almost ready to support all the changes in 4.1, allowing you to wrap packages into PSADT faster and without errors using our UI. MW will be available to everyone next week.

It's here - a first release of RdpCredProv, a Windows credential provider with autologon capabilities better than the original! 🚀 Yes, it works even with the Hyper-V enhanced session mode! Grab a copy from github.com/Devolutions/RdpCr… and then follow the instructions from the readme 👇

The Winlogon registry keys for autologon don't work with the Hyper-V enhanced session mode, so I undusted an old credential provider in C++, made it load default credentials from the registry, and poof, it works! This will be very useful for lab environments 👇
