Hello Merina,
Welcome to the Microsoft Q&A and thank you for posting your questions here.
I understand that you are asking how to install the newer FSLogix, and while the AVD machines are in use (and using FSLogix).
Yes, you can install the newer FSLogix while the Azure Virtual Desktop (AVD) machines are in use. However, updating an application that is currently running can be challenging and could potentially fail if the application is in use. Therefore, it is generally recommended to update the application when it is not in use.
You can deploy the newer FSLogix Apps to the Azure Virtual Machines using InTune with the following install switches: /install /quiet /norestart. Your AVD machines can continue running in multi-user mode during this process.
After the installation, the newer FSLogix Apps will take over when the AVD machine reboots, which could occur due to a scaling plan, or a power off and power on event¹.
There are also alternative ways to update FSLogix:
- Scripted Actions with Nerdio.
- Scheduled Task or Group Policy Object (GPO).
