Powershell command to see what’s installed

  • Article

Here is a quick little Powershell script that I find useful to see what I have installed on my system.

This will return the installed program and the date that it was installed:

get-wmiobject -class "win32reg_addremoveprograms" -namespace "root\cimv2" | select-object -property Displayname,Installdate

To run this against a remote computer just add a –Computername “computername” before the first pipe.

    Our friend, Tim Mintner posted a great PowerShell script today on his blog.

    It should be noted that this will only find software that puts a key in the add/remove registry hive. Since that covers 905% or more of installed software, it is still useful code. Thanks for sharing it.

    That is a very good point EBGreen.  Most programs add keys to add/remove but this won't work for old DOS programs or very old Windows programs.
