Run this to update your current folder:
"C:\Program Files\TortoiseSVN\bin\TortoiseProc.exe" /command:update /path:"." /closeonend:1
This will run the same graphical GUI as the regular "right click -> Update" but it will close the windows if no errors occur.
Make things easier for you and add the Tortoise bin folder to your PATH.
