How to track and maintain installed programs with registry keys using PowerShell "get-itemproperty" on Windows 7? I know how to use PowerShell cmdlets.

If you want to get a list of all installed applications on your Windows 7 based on registry keys with PowerShell cmdlets, you can use the "get-childitem" cmdlet as described in this tutorial:

1. Start a PowerShell window

2. Run the following command to dump the "Uninstall" registry entries:

PS C:\fyicenter> get-itemproperty 
   HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*
   > Installed-Programs_Keys.txt

3. Open Installed-Programs_Keys.txt in Notepad. You see a list of installed programs recorded in the file, as shown in the example below:
