How to track and maintain installed programs with PowerShell 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 with PowerShell cmdlets, you can use the "Get-WmiObject" cmdlet as described in this tutorial:

1. Start a PowerShell window

2. Run the following command.

PS C:\fyicenter> get-wmiobject -class Win32_Product > installed-programs.txt

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