Given that windows administration is powershell these days they kind of are similar.

Windows is missing so much in their guis abilities (like copy text) that I wonder what there is you are missing.

Edit: Although this is not an admin function, one thing that bothers me about windows, A LOT is that the file explorer does not show free space while I am in the current directory. Dolphin will do it even for SMB shares. Also you can click the drop down and examine all drives right there instead of have to back to the left and ruining your view in explorer. And don’t get me started about how you can’t split views in Windows explorer. This is just one everyday task where windows GUI is lacking in features even though it is not an admin tool.
