Click your Start Button, type regedit and hit Enter to open the Registry Editor
Note down the name of your network connection (ProfileName)
In the left pane, navigate to:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles
Expand the Profiles Key (folder)
That will contain sub-keys with different GUID's
Click each Sub-key
On the right, check the ProfileName value
When you find the sub-key with the correct ProfileName value
At the top you will see 'Category' - double click that
Change its value to 0
Click OK
Close the Registry Editor and restart your PC
This is an easy way and works ok. Anyway thanks for your answer.
