Solution for: Folder View Settings aren't saved (also - Quick Launch Dissapear after shutdown) :
A) In any folder, click "Tools" (in the Menu bar) > click "Folder Options", click "View" tab, in "Advanced Settings" list, find and check mark "Remember each folder's view settings" (also, ensure that "Do not cache Thumbnails" is not checked). Then,set the view of any folder as you want, then go to the "View" tab in "Folder Options", and click the "Apply to all folders" button.
B) If the above wont solve your problem, then use this:
click "Start > Run" and enter these 2 commands (one by one)
REG ADD "HKEY_Current_User\software\microsoft\windows\currentversion\policies\explorer" /v "NoSaveSettings" /t REG_SZ /d "0" /f REG ADD "HKEY_Local_Machine\software\microsoft\windows\currentversion\policies\explorer" /v "NoSaveSettings" /t REG_SZ /d "0" /f
Then restart the computer.
after windows logon, ensure that the Quick Launch Toolbar is ticked via right click on taskbar>toolbar>tick quick launch. Restart the computer a second time!!! That's all.
