Reloading NTFS permissions without logging out/in of your sessions

The command below lets you log out of your Windows session and in again, without closing your application. This, among other things, allows you to access a newly shared folder without logging off/on.

(It's of course better to make sure you're not using session related functions before restarting the explorer.)

taskkill /im explorer.exe /f & start "" "c:\windows\explorer.exe"
