Can AeroPeek in a win7 computer be faster?

Speaking of the AeroPeek function, I believe that everyone will not be unfamiliar? For the gorgeous win7 32-bit pure version, the AeroPeek function will definitely give you more powerful practicality. Even with multiple windows and multiple tasks enabled, the AeroPeek feature allows us to query the desktop state with one click.
But on the other hand, many friends also found that when using the AeroPeek function, there is often a delay. Although it may be only 1 second, it still feels a little uncomfortable, so I want to know how to Let AeroPeek function "fly up"? Let's set it up according to the introduction of Xiaobian!
1. Press win+r at the same time, then type regedit in the run window and click Enter. You can open the Registry Editor window.

2. In the left window of the Registry Editor, expand HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced, then right click in the blank space of the right window - New DWORDS (32-bit) key value.

3. Rename the newly created 32-bit key value to DesktopLivePreviewHoverTime.

4. Double-click the DesktopLivePreviewHoverTime file, and then change the value of the numeric data to a number between 500 and 2000, and the base number to decimal.
After completing the above settings, we need to restart the computer, then the above settings will take effect!
