Click Start. 
A new System Folder is installed on your hard disk. (The old System Folder is renamed Previous 
System Folder.) 
Reinstall extensions, control panels, and other startup items not installed with Mac OS 7.6 from their
original disks, if possible. If you don’t have the original disks, you can drag these items one at a time
from the Previous System Folder to the new System Folder. Restart your computer after you reinstall
each item, to make sure your software is compatible with Mac OS 7.6. 
Rebuilding your desktop
A procedure known as “rebuilding the desktop” helps your Macintosh to keep accurate track of data on
your startup disks. Even though rebuilding the desktop does not usually fix problems once they occur,
it does prevent some types of problems. Therefore, it’s a good idea to rebuild your desktop once a
month or so.
Before you rebuild the desktop, you’ll need to turn off some extensions, which may interfere with the
desktop-rebuilding process. You’ll turn them back on later.
To rebuild the desktop, follow these steps:
1
Open the Apple (K) menu and choose Control Panels. Then double-click the Extensions Manager
control panel to open it.
2
Open the Edit menu and choose All Off.
This turns off all extensions. You’ll notice that none of the items in the Extensions Manager’s list 
is checked.
