Ying Li has a cool PowerShell Script to list installed Software on a local computer HERE.
When I looked at it and thought to myself, I can do that with 1 line (if I cheat a little). Here it is:
PS> gp HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* |Select DisplayName, DisplayVersion, Publisher, InstallDate, HelpLink, UninstallString |ogv
HI Jeffrey. That's nice but you forgot there's atleast 2 other registry keys you need to list! How do you do that with one line so all the results are sortable in Out-GridView. I'd be very excited to learn this.
HKCU SOFTWARE\Microsoft\Windows\CurrentVersion\UninstallHKLM SOFTWARE\Microsoft\Windows\CurrentVersion\UninstallHKLM SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall
(on one line without making a script file).
My C# version.
