I Try to turn aero peek off but 1)Unchecking in Taskbar Properties dostn work 2)Control Panel ->Visual Effect unchecking dosn't work.

Registry Method
1: Open RegEdit and go to HKEY_CURRENT_USER\Software\Microsoft\Windows\DWM
2:In Right Side Pane Double Click on "Enable Aero Peek" as in above image and type Value As 0
3: Reboot
Easy Method 1: Right-click on Computer icon on Desktop and select Properties (or press WIN + Pause/Break keys). Now click on Advanced system settings link in left side pane (You can open it directly by giving sysdm.cpl command in RUN or start menu search box).
2: Now click on Settings button in Performance section:
3: Now uncheck "Enable Aero Peek" option.
4: Click on Apply button and it'll disable "Aero Peek" feature in Windows 7.
I think the question may actually be about Aero Shake not Aero Peek.
Aero Shake is shaking a window to display the desktop. Aero Peek is placing the mouse over the rectangle at the right of the taskbar to display desktop.
To turn off Aero Shake enable the following setting in the Local Group Policy Editor "gpedit.msc".
User Configuration\Administrative Templates\Desktop\Turn off Aero Shake window minimizing mouse gesture
Hope this helps.
