Question

Using PowerShell, I can do:

$shell = new-object -com Shell.Application
$shell.GetSetting(0x2)

Which correctly returns whether the shell shows extensions for known file types.

Note: see http://msdn.microsoft.com/en-us/library/gg537739(v=VS.85).aspx for a list of flag values that can be passed to GetSetting.

Question: I can get the values, but how would I change them? I looked through the Shell object model, but I’m just not seeing it a matching method to do that.

Answer 1

Not exact answer, but you can edit registry?

For example:

set-itemproperty -Name HideFileExt -Value 0 -path HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
