FSLogix is a set of solutions that enhance, enable, and simplify the non-persistent Windows computing environments. The solutions are applicable for Cloud, Virtual, Physical, and even mixed environments. It works on reducing hardware, software, and management overhead while boosting the user’s experience.
One of the key features of FSLogix is application masking. In this article, we will look into how to implement FSLogix application masking, an important aspect when preparing for the AZ-140 exam which focuses on Configuring and Operating Microsoft Azure Virtual Desktop.
What is FSLogix Application Masking?
Application Masking is a feature within FSLogix that delivers applications based on rules. A rule specifies whether an application or a file is visible to a certain group of users.
Application masking in FSLogix leverages the concept of filter drivers to control visibility and access to installed applications. By using the rule sets, IT administrators can simplify the process of managing large groups of users, removing the need for complex GPO or scripting strategies.
Utilising FSLogix Application Masking
When it’s implemented, FSLogix makes every application look as though it was natively installed, notwithstanding the manner of its presentation. The applications ‘install’ in seconds, regardless of the size or complexity of the application. They don’t have to be virtualized, sequenced or altered in any way, which continues to help simplify app management.
Implementation
Here is a simple manner to implement FSLogix application masking:
- Step 1: Create the Rules
- Step 2: Configure the Rules Assignment
- Step 3: Deploy the Rules to the FSLogix Rules Share
- Step 4: Test the configuration
In the FSLogix Apps Rule Editor, you can either choose from predefined templates or create your own rules manually. The App Rule Editor enables an administrator to create include and exclude rules. Include rules designate which Named Objects should allow the applications associated with the Rule Set to load. Conversely, exclude rules designate which Named Objects should prevent the apps from loading.
Once the rules are created, they need to be assigned to user groups. This is done through the Rule Assignments tab in the Rule Editor. Here, administrators can add the user groups that will have visibility to the applications associated with the Rule Set.
After the creation and assigning of rules, the next step is to deploy the rules to the FSLogix rules share that the client machines have configured.
After deploying the rules, it is fundamental to test the configuration on a client machine that is a member of one of the groups assigned to the Rule Set.
Limitations
There are few limitations to using FSLogix, including:
- The users may experience slower logins because full user profiles are loaded at login.
- FSLogix doesn’t support multiple sessions per user.
- FSLogix is not the solution for managing user data, it merely replaces roaming profiles.
Conclusion
FSLogix provides a powerful tool to simplify application management in virtual desktop environments. By implementing application masking through FSLogix, IT administrators can significantly reduce the hassle associated with traditional application deployment and management techniques. Hence, mastering FSLogix and its application masking feature can prove to be a significant step when preparing for the AZ-140 ‘Configuring and Operating Microsoft Azure Virtual Desktop’ examination.

Interview Questions
What is FSLogix application masking?
FSLogix application masking is a feature that allows administrators to hide applications or certain components of an application environment, depending on the user’s rights, resulting in a more personalized and streamlined experience for the end-user.
How does FSLogix application masking contribute to Azure Virtual Desktop?
Within Azure Virtual Desktop, FSLogix application masking can be used to simplify management and enhance performance by only providing access to the necessary applications for each specific user, reducing the overhead and increasing the system’s resultant speed.
What requirements must be met to use FSLogix application masking?
To implement FSLogix application masking, you need an FSLogix Apps agent, which is compatible with Windows client operating systems from Windows 7 and Server 2008 R2, and newer. The machine should be joined to a domain and have enough storage for FSLogix profiles.
How does FSLogix application masking improve the user experience?
FSLogix application masking enhances the user experience by customizing and simplifying the virtual desktop environment. It restricts the visibility and access of irrelevant applications, which helps to avoid clutter and confusion for end-users.
In what scenarios is FSLogix application masking beneficial?
FSLogix application masking is beneficial in instances where administrators want to assign different application access to different users, based on their roles or departments within an organization, without maintaining multiple base images.
What is the basic operation involved in FSLogix application masking?
FSLogix application masking primarily involves setting up rules for the visibility and usage of applications. These rules are then assigned to groups or individual users, controlling who can see and use specific software.
Which component of FSLogix is responsible for the assignment of application access rules?
The Rules Editor, which is part of FSLogix, is used to assign the application access rules. Administrators can define rules and save them as XML files, which are then associated with groups or individual users.
What is an FSLogix Rule Set?
An FSLogix Rule Set consists of an XML file and an optional assignment file that determine which users or groups a particular rule applies to. Multiple rules can be combined into a Ruleset to create complex application control scenarios.
How does FSLogix application masking handle user rights?
FSLogix application masking uses Active Directory to establish user rights. The machine’s local Security Group membership determines which rules from the Rulesets are applied to a specific user or session.
Can FSLogix application masking be used to hide specific files or Windows registry values?
Yes, FSLogix application masking allows administrators to hide or make specific files, registry keys, or values, appear to be nonexistent to a user or a group of users. This can be very helpful in managing complex application environment configurations.
