I have a brand-new OEM Windows 7 computer from Acer. When I click on any item in a jump list, apart from the items "Close window", "Pin this program to taskbar" and the one that actually starts the program, it just opens C:\Windows\system32. The same thing happens when I use Task Lists from the Start Menu, when I click any button or link of a certain type in the Control Panel, and in other places as well. Among the buttons and links that don't work are (in the Backup section): the "Back up now" button, the "Manage space" link, the "Turn on schedule" link, the "Change settings" link, "Restore all users' files", and "Select another backup to restore files from". "Recover system settings or your computer" and "Restore my files" work fine, however.

Does anybody have this issue? How can I fix it?
