powershell: listing stuff from add/remove programs

heard from my buddy stefan stranger today and was discussing how to get information from ARP.  this is what we came up with:

my method

dir "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" | % { get-itemproperty $_.pspath }

 

his method

get-itemproperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*

 

his method requires less typing but in actuality took longer -- usually about twice as long.  still too fast to notice the difference but interesting anyway.  must be the wildcard.

measure-command {dir "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall" | % { get-itemproperty $_.pspath }}
