|—-WEM – Be careful with the “registry inclusion” setting for UPM
If you are using WEM to control Citrix UPM/Profile manager settings. Be very careful with the setting for “registry inclusion”.
You may think this gives you the option to include some registry settings here that’s not beeing taken care of in other means.
Do note that, checking this box, and adding items in this area, makes WEM ONLY include the selected entries and ignore all others. 
|—-Google Chrome – No audio in ICA session after version 77
If you are experiencing missing audio playback in Google Chrome inside an ICA session. Check if your version is above v77 of Chrome.
If you are, you can work around the issue by the following.:
1 – By editing the registry.:
HKCU\Software\Policies\Google\Chrome – to apply on the user level
or
HKLM\Software\Policies\Google\Chrome – to apply for all users on the machine
add a DWORD value named “AudioSandboxEnabled” and set the value to “0“
2 – By editing the published application // shortcut for the application
Add one of the following as an argument for the shortcut:
“–disable-features=AudioServiceSandbox “
or
“–disable-features=AudioServiceOutOfProcess “

|—-Server 2019 NPS firewall bug
In server 2019, there seems to be a bug when using the NPS server role for Radius authentications.
The default port 1812 UDP is open on the server after insta, but does not accept connections.
Workaround is to create a new inbound rule to open UPD 1812.
More information on this can be found in my post about the subject here:

|—-Applocker breaking startmenu on server 2016+
If you are using applocker on server 2016 you may see issues around the start menu.
I found this to be an issue when provisioning Citrix VDA’s where AppLocker is enabled only for EXE rules.
The issues shows itself by:
Left clicking the start menu, the menu does not come up.
Right clicking gives your the default right-click meny context.
Issues comes from AppLocker missing the default APPX package rules.
You need to edit your GPO on a computer where these settings are available (2012r2+)
Enable the default APPX package rules in applocker and your should be good to go – no need to set the APPx rules to enforces status.
AppLocker seems to relate to these even if they are not enforced – so the defaults need to be there.
Kasper Johansen also wrote more details around this on this post back in 2017.
