Disable taskbar tooltips in windows 7
Open "regedit" as adminstrator.
Navigate to:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
Find "ShowInfoTip", right-click and select "Modify" and change the value to "0"
You might be experiencing this issue, described on Microsoft's Q/A forum:
Why does the tooltip display on taskbar icons when I am not hovering my cursor on them?
The suggestion there is to make sure your video drivers are up to date. For a momentary fix, you can try:
- Holding Shift and right-clicking on a tile.
- If that doesn't work, try killing
dwm.exe.
Click Start>Run, type Gpedit.msc. Under User Configuration>Administrative Templates>Start Menu and Taskbar, enable 'Remove Balloon Tips on Start Menu items'
