Powershell scripts
In this section, I have provided information about the PowerShell scripts I have created.
However, this does not include all of the scripts I have
.Shrink VHDX disks
In our environment, we use
FsLogix and VHDX disks. VHDX disks are fixed-size and are not expandable in our
environment. When a user logs into Citrix, their VHDX disk is attached to the
computer, and the user can work without experiencing any lag. However, as you
know, when working with a Windows computer, user profiles fill up with all
sorts of temporary data, which takes up space and can fill up the entire VHDX
disk.
To prevent this from happening, I wrote a PowerShell script that mounts the user's VHDX disk, deletes all unnecessary data, and shrinks the disk.
This way, the user's disk is always kept clean and does not fill up completely. In addition, we save money on data center storage space, because the more space we use, the more it costs.
1. Reduces Storage Consumption

Overall Value
This PowerShell script automates the maintenance of FSLogix profile VHDX disks by removing unnecessary temporary data and shrinking the disks to reclaim unused space. It helps prevent profile disks from reaching capacity, improves the stability of the Citrix environment, reduces administrative effort, and optimizes storage utilization. By reclaiming unused space, the script also lowers data center storage costs and provides a scalable, proactive solution for managing FSLogix profiles across the organization.Windows OS computers waiting for reboot after windows monthly patching
After Windows updates are installed on Windows computers, the Windows OS usually prompts you to restart the computer. However, for a variety of reasons, you might not see this prompt and may not realize that the computer is waiting to be restarted. To avoid such issues, I wrote a PowerShell script that scans computers on the network and checks whether a computer is waiting to be restarted after a Windows update has been installed. The information is collected in a CSV file and sent to Citrix support agents.
Here are the key benefits:

By automatically generating a CSV report and notifying the Citrix support team, the script helps ensure that Windows updates are fully applied and reduces the operational risks associated with delayed system restarts.Find Disconnected Citrix sessions
Users very often leave their
Citrix sessions in a disconnected state on Citrix single-session machines. And
until they log out completely, no other user can log in. I created a PowerShell
script that collects information from Citrix DAAS about disconnected sessions.
It then retrieves the user’s email address from Active Directory and sends the
user a message about their disconnected session, along with instructions to
sign out of the VDI computer next time.

By identifying disconnected sessions, retrieving the corresponding users' email addresses from Active Directory, and sending personalized reminders to sign out properly, the script helps ensure that virtual desktops are released promptly for other users.Find Unused files in users Citrix profiles
We noticed in
our Citrix environment that users often leave unused files in their Citrix
profiles, which take up space. I wrote a PowerShell script that collects
information about the user folders in the Citrix profile, their sizes, and when
they were last accessed. If a folder hasn’t been accessed for more than a year,
all this information is compiled into a table and sent to the user as a
reminder that the Citrix profile is not intended for storing files for long
time. It is intended for storing files that are currently being worked on.

Find Citrix unregistered computers
If the connection to the Citrix DAAS is lost on a user's
computer where the Citrix VDA agent is installed, the computer switches to
"Unregistered" mode. We can see these computers in the Citrix DAAS
console, but we don’t monitor the console all the time. To detect such
computers more quickly, I wrote a PowerShell script that identifies computers
in “Unregistered” mode and sends this information to Citrix support team agents
via email.

Find stuck machine
There are situations where a
Windows OS computer freezes, and Citrix DaaS doesn’t always detect it. As a
result, you might not even notice that the computer has frozen until users
start complaining that they can’t log in to it. To avoid such situations, I wrote
a PowerShell script that allows you to find unresponsive computers. However, it
doesn’t rely solely on the ping command. The PowerShell script scans for
powered-on computers using the quser command and waits one minute to see if the
computer responds. If the computer responds, the script moves on to the next
computer. If the computer does not respond, the script treats it as frozen. The
computer's information is then logged in a log file, and Citrix support agents
are notified via email about the frozen computer.
Benefits of the Frozen VDI Detection Script
1. Detects Frozen Computers That Standard Monitoring May Miss
· Identifies Windows computers that are powered on but no longer responding.
· Detects issues that may not immediately change the machine's status in Citrix DaaS.
· Complements existing Citrix health monitoring.
2. Reduces Service Disruptions
· Enables support teams to identify frozen VDIs before they generate multiple user incidents.
· Helps maintain a healthy pool of available desktops.
· Reduces the impact of unresponsive machines on end users.

Automatically delete non-existent Citrix users
In our Citrix environment, many
Citrix users have access to single-session virtual machines. Not all of them
use virtual machines at the same time. However, the problem is that some users
leave the organization and their accounts are deleted from Active Directory,
yet they still retain access to Citrix single-session virtual machines. Going
through and checking whether each user’s account exists in Active Directory
would take a very long time.
I wrote a PowerShell script that checks whether user accounts exist in Active Directory. If the account exists, no action is taken; if it does not exist, access to that account is revoked from the Citrix single-session virtual machine.
All of this is done automatically, and no user intervention is required.
A log file is also created and sent to all Citrix agents via email

This PowerShell script automates the synchronization of Citrix single-session virtual machine assignments with Active Directory by removing access for users whose accounts no longer exist. It improves security, optimizes desktop utilization, reduces administrative effort, and ensures that Citrix resources are allocated only to active users. By generating logs and notifying the Citrix support team, it also provides transparency and an audit trail for ongoing operational management.
