windows 7 : how to restore volume icon in system tray

kristen May 15, 2009 4:22pm BST 1. Back up the Registry by creating a restore point. 2. Go to Start > Run (or Windows-key + R), type in regedit and hit OK. 3. Navigate to the key HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify. 4. Delete the values IconStreams and PastIconsStream. 5. Open up the Task Manager (Ctrl + Shift + Esc), go to the Processes tab, select explorer.exe and click End Process. 6. Open the Applications tab and click New Task at the bottom-right of the window. 7. In the message box that pops up type in explorer.exe and hit OK. 8. Explorer.exe will reload, and the missing icons should now be back in the system-tray where they belong. 9. Then if the volume bar isn't there, go to taskbar properties (where the volume was gray) and simply tick the box. from : http://en.kioskea.net/forum/affich-31257-how-to-recover-lost-missing-system-tray-icon

auto logon for Windows Vista/7

Make Windows 7 or Vista Log On Automatically
If you are just running a home computer for gaming or something unimportant, you might not want to have to log in every single time you reboot your computer. There’s an easy tweak that will let you autologin.

First, we’ll need to get to the Advanced User Accounts Control Panel to get to this setting. I think there’s a registry tweak as well, but that seems like too much work.

Type in netplwiz into the start menu search box, hit enter, and you’ll see this screen:

Note: If that doesn’t work, you can type in control userpasswords2 instead.
