Disable Narrator keyboard shortcut in Windows 8

I have pressed Win Key + Enter many times while attempting to press Alt + Enter, and every time I have to listen to the Narrator speak out the process of me closing the narrator. Here is how to disable the narrator keyboard shortcut by disabling access to Narrator.exe.

• Navigate to %systemroot%\System32
• In this folder a file called Narrator.exe is to be found
• Right click the file and choose Properties
• Choose the Security tab and press Advanced
• In the top of the window press Change to change the Owner permissions
• In the text field write your username and press OK to all the dialogs

Now you should be able to change the permissions of the file, this is where we remove all the permissions from your user and the user back to system, this way your user will not be able to start the Narrator.

• Right click the Narrator file again and choose Properties and Security tab
• Press Advanced
• Now that you are the owner you can change permissions for other users. Choose your own user and press Edit
• Remove the Read & Execute and Read permissions and press OK
• Now press Change in the top under Owner and write system in the text field
• Press OK to all dialogs

Networks are not scanned or refreshed when clicking on the wifi icon or Show Networks (Mac OSX)

Update: This is a bug. I have confirmed this with Apple today. It will be fixed in a future update. The steps below did not fix my issue. The issue reoccurs when going to the login screen and then logging in again.

When I click on the wifi icon on the Menubar, the networks are not scanned and there is no rolling radial wheel. When I click "join other network" and "scan networks" the list remains empty. This is how I remedied the issue, with help from apple:

• Open a finder window
• Click the "Go" menu and then "Go to folder"
• Go to ~/Library/Preferences
• Drag com.apple.systempreferences.plist to your desktop
• Restart
• Fixed!

On a side note, this was a profile issue for me. We checked that by creating a new user account and logging in with that one and the issue wasn't there.

apt-get extremely slow to resolve domains?

It's probably trying to do DNS resolution through ipv6 which is not configured. You can edit

/etc/gai.conf 

and add the line

precedence ::ffff:0:0/96  100

to the end of the file. This way DNS lookups are done with ipv4 prioritized over ipv6.
