"Aero Peek" is a new feature in Windows 7 which has replaced the old "Show Desktop" shortcut. It can be found as a small rectangle present at the end of Taskbar. When you hover the mouse cursor over it, it allows you to peek behind all open windows by hiding all windows and showing only outlines of all windows.
The default delay time to preview Desktop is set to 1 second by default but sometimes it gets annoying when you accidentally hover your mouse over it.
Today we are sharing a small registry trick which can be used to adjust this delay time. You can set the delay time to 2,3 or more seconds according to your requirements.
So here we start the tutorial:
1. Type regedit in RUN or Startmenu Searchbox and press Enter. It'll open Registry Editor.
2. Now go to following key:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced
3. In right-side pane, create a new DWORD value DesktopLivePreviewHoverTime
4. Now you'll need to set its value to your desired delay time. Double-click on it and select "Base" as Decimal and enter the desired value. Remember the value should be given in milliseconds, so if you want to set the delay time to 4 seconds, set the value to 4000
5. That's it. Log off or restart your system to take effect.
NOTE: If you want to restore default settings, simply delete "DesktopLivePreviewHoverTime" DWORD value created in Step 3.
PS: If you want a ready-made script to do the task automatically, download following ZIP file, extract it and run the extracted REG file. It'll ask for confirmation, accept it:

Why would you want to change the delay to 4 seconds? That would make aero peak as good as completely useless because you'd need to hover over for ages to get it to show.
I would prefer it to be the same time as the aero thumbnails when you hover over the icons in the taskbar because then it will do it instantly when you want to show desktop and take advantage of the feature, but won't be too long so that have to wait for ages.
Other than that, it's a great tutorial because you've shown us which registry key it is to change this setting.
