No, App-V is not EOL in April 2026

No, App-V is not EOL in April 2026

a few weeks ago, a customer wrote to me saying that App-V is to go out of support in 2026 after all. 2026? Where did the new date come from? There was the problem that many thought App-V was going out of support in 2025 because the Microsoft Desktop Optimization Pack (MDOP) had been announced for that date. The MDOP includes, among other things, the App-V infrastructure for distributing App-V packages to endpoints. But the App-V client itself was integrated into the operating system starting with Windows 10 1607 (at that time also in Windows Server 2016). App-V packages can also be distributed by other means (PowerShell) or another deployment method like Endpoint Configuration Manager. So nothing to worry about.

Hidden App-V Registry Keys

Now since 2004 I have been implementing projects with Microsoft App-V (then Softgrid) and yet the product surprises me again and again with unknown elements. After the M.A.D. Day 2019 we had a TroubleShooting Session with Sebastian Gernert. We noticed that App-V always accesses the registration key "HKLM\SOFTWARE\Microsoft\AppV\Subsystem\Disabled\". It was on my todo list for a long time to analyze this key once. Now I finally got around to it. At first we created a key "Disabled" and already a number of subkeys like "Integration", "Virtual Fonts", "Virtual Services" etc. appeared in ProcMon.
So the App-V client has some hidden registry keys to disable the different subsystems globally and this can be very useful.

SQL Server Management Studio 18.5 (SSMS) App-V Recipe

The old recipe for SSMS 17.x was a nice success for me with about 1000 hits. Especially the comments were enlightening. The licensing problem could be solved with a simple registration key. With 18.5 there is nothing more to do here.

App-V Link Cleanup Script

Again and again we had to find out that sometimes App-V shortcuts in the user profile or even globally on the back. This can happen for various reasons. In particular, after a missing unpublishing for a user even if the package no longer exists. For nonpersistent VDI or Terminal Server this is no problem in the global context under C:\ProgramData\Microsoft\Windows\Start Menu\Programs, because the systems are always in their original state after a reboot.For user profiles, however, this is a problem.
Since I have a little more time right now, I finally get to publish the script I created a long time ago for this problem.

App-V Registry Staging Problems With Citrix PVS (MCS Images)

A few weeks ago, one of our customers experienced the problem that some App-V applications were not started until the second start. This seemed to be caused by the registry staging of the App-V application. With App-V Registry Staging, data from the application is copied to the following area of the registry when the application (Publish AppVClientPackage) is released.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\AppV\Client\Packages\<PACKAGEID>\Versions\VERSIONID\REGISTRY

When the action is complete, an empty key RegistryStagingFinished is generated.
