W7 Ep 1 - How To Remove the Ugly "Send Feedback" Link in Windows 7 Beta (HD)
Note: before we get into how to disable this, you should think about whether you really want to do it. Keep in mind that this is a Beta version of Windows, and it's only YOUR feedback that is going to make Microsoft change or fix anything before the release, so you should be submitting as much feedback as you can.
Manual Registry Hack
The first thing you'll want to do is open up regedit.exe through the start menu search box, and then browse down to the following key:
HKEY_CURRENT_USER\Control Panel\Desktop
Once there, find the FeedbackToolEnabled key on the right-hand side, and change the value to 0.
To revert it back, change the value to 3 again.
Sending Feedback Alternately
There are a number of ways to launch the feedback tool even after disabling the link the most obvious is the big icon right on the desktop but you might have deleted that already.
You can just type "feedback" into the search box, and launch the tool from there
Or you can find it in the control panel.
You'll have to log off and back on for the change to take effect.
