When using Microsoft User Profile Disks you also know the tool Sidder: https://gallery.technet.microsoft.com/Sidder-Quickly-see-which-fa6360b3
This tool will show the username who belongs the the User Profile Disk.

I’ve found this not so conveniant as you must run it every time you want to know the username.

So I dusted off my powershell skills and created this little powershell script which will add a text file next to the UPD with the username at the end of the filename.

Keep in mind, I’m not a devver, so I’m sure you can make this PowerShell script in a one or two liner but hey, it just works. 😉

My LAB UPD Store look like this at the moment:

After running the script it looks like this:

You can schedule this script to run every night. Or manually when needed.

I found this script from https://learn.microsoft.com/en-us/answers/questions/1005700/show-usermame-linked-to-upd-drive

I would like to point out that your script doesn’t properly handle the situation where the user has been deleted. The script will apply the username from a previous file, because the variables are not initialized each time.

I am not a coder either, but I have updated the script to put “UNKNOWN” if the SID cannot be translated back to a username.

#——————————– Script ——————————–

$Files = gci $UPD_Location -Name

Foreach ($SID in $Files) {
If ($SID -match “.vhdx”) {
$SID = $SID.Substring(5) -replace “.vhdx”
If ($SID-match “template”) {
Write-Host “Template File”
} Else {
$objUser = “UNKNOWN”
$UserName = “UNKNOWN”
$objSID = New-Object System.Security.Principal.SecurityIdentifier ($SID)
$objUser = $objSID.Translate( [System.Security.Principal.NTAccount])
$UserName = $objUSer.Value.trim(“$DomainName\”)
$TextFile = $UPD_Location + “\UVHD-” + $SID + ” ” + $UserName + “.txt”
New-Item $TextFile -ItemType file -Force

    Hi Kevin,

    UPD should not be used anymore. You should switch to FSLogix 😉
