Get the Data values from the registry using powershell - powershell

Question

I am trying to add an application in 'DisallowRun' registry key to avoid running application to specific users. Need to add the application if not exist. Consider 'TestApp3.exe' in this case.
Used below query to get the list of items in the key. It is giving Name(Key Name), Property(Name Value : Data Value)
Get-Item -Path "Registry::HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\DisallowRun"
Output
Name Property
---- --------
DisallowRun 1 : TestApp1.exe
DisallowRun 2 : TestApp2.exe
DisallowRun 3 : TestApp3.exe
DisallowRun 4 : TestApp4.exe
When i use .Property in the code, getting only Name Values and not Data Values
(Get-Item -Path "Registry::HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\DisallowRun").Property
Output
1
2
3
4
If i get only the Data Values (similar to below) then i could have use contains function to check the specific application is already available or not. Please help me to get only Data Value or is there anyway to check the application is exist in the registry key.
TestApp1.exe
TestApp2.exe
TestApp3.exe
TestApp4.exe
