Click Start – Run - regedit and press enter. This will open the Windows Registry Editor.

Now, navigate through to


Look for the DWORD ShowInfoTip, right-click and select Modify and change the value data as required

1 – Enable ToolTips (Default)

0 – Disable ToolTips

Restart your machine. This should disable all the tooltip's.

Edit : Updated one more way to disable tooltips:

HKEY_USERS\.DEFAULT\Control Panel\Desktop . On the right pane, double-click UserPreferencemask and change the value to 3E 00 00 00. Take a backup before you change this value.

Thanks very much, but should I restart windows? – Hossein Margani Jun 7 '10 at 5:50
Yes. I guess... – ukanth Jun 7 '10 at 7:05
:( still I see hints. – Hossein Margani Jun 8 '10 at 7:38
Windows tool tips (operating system) are not the same as VS hints (application). – kmarsh Jun 8 '10 at 12:32
