I have installed Powershell 5 on Windows 7.
help get-childitemdoes not show -Attributes parameter.
help get-childitem -showwindowdoes not show full help although is checked in settings.
What’s wrong with my system?
Have you run Update-Help?
That’s a dynamic parameter, and I think I’ve seen some messages going around that have said there’s a problem with Get-Help and dynamic params at the moment. You can get information about them with “Get-Help FileSystem” (or substitute another provider name there if you want that provider’s params.)
I have run Windows Update, then I have run
Update-Help -Force
I wonder if my problem has anything to do with Powershell 2, which is also installed.
Dave is right. The help system is in some places broken/not up-to-date. June Blender already opened a bug on uservoice, you can vote here: https://windowsserver.uservoice.com/forums/301869-powershell/suggestions/15487608-help-for-filesystem-dynamic-parameters-of-get-chil
So this is not a problem on your computer, and has nothing to do with PowerShell v2 installed. Just a bug.
OK, thank you every one
