By default, Windows show short information as tool tip when you hover mouse over the Minimize, Restore or Close buttons of a program or an application. This setting can disable this feature.
For this, go to Start > Run menu, enter “regedit” and navigate to the registry path listed below. Now, right-click and modify the Binary value “UserPreferenceMask”, in the right panel. The new value should correspond to the chart given below depending upon the default value on your system. Remember:
Only the first number / character of the binary value should be changed. Say if the default data value in “9E 3E 07 80”, the changed value will be “1E 3E 07 80” i.e. the first number “9” should be replaced with “1”.
|First Number/Alphabet||Replaced Value|
However, if you want to enable tooltips back, change the value data to original.
The changes take effect after a restart or logoff.
