How to forbid Speed up browsing by disable add-ons

You may often see this popup when every times you open you IE9 browser to surf.

It is really disappointing, at least I feel so. But how to forbid it? Easy, there are two methods:
A. Forbid this notification directly, I call it direct method;
B. Don't let it appear easily, I call it indirect method.
They are explained below:

A. Direct method
1. Win Key + r and type in regedit, and Alt + y to open window's Registry Edit

2. Go in \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies

3. Right click Policies node and create a new key, name it Ext

4. Click Ext just created, on right side empty place right click and select DWORD(32-bit)Value

5. Name it DisableAddonLoadTimePerformanceNotifications

6. Double click this new created item, set value to 1, by default it's 0

7. Click OK, exit registry edit, and restart your IE9 browser.
You will find this notification is gone. But how to let it back? ... This is another question! :)

B. Indirect method
This notification is for telling you the add-ons increase the time to start the browser,open a new tab or navigate to websites and is only displayed when this time exceeds a certain time. We can set up a very long time so that the start time will not exceed it.
1. Display Command bar of your IE9

 Then you can see

2. Open Toolbars --> Disable add-ons

3. Set up a very long limit time, select the longest time option, 10.0 seconds

4. Click Done. Start a new tab, this notification should be gone.

5. If you want to let it come back very easy. Just set a short time.
