Streamline and then optimize the old computer to turn off the Win10 taskbar preview

Windows 10, although the system’s resource consumption is lower than that of Windows 8, can also be used normally on older computers, but some of the features in the settings can not be completely closed, such as the performance of the graphics card and processor requires high background program preview function, which consumes a considerable amount of system resources. If you want to turn them off completely to make Windows 10 smoother, you need to start from the registry.

First, click on the Start menu, then type “regedit” and enter to enter the Registry Editor.

002

After that, locate the “HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerAdvanced” section in the Registry Editor.

003

Then click the “Advanced” item, find “ExtendedUIHoverTime” in the right window bar, double-click to open, edit and modify the DWORD (32-bit) value to hexadecimal “9000”.

004

Note that if the installed version of Windows 10 is relatively new, there may not be the DWORD value, you need to manually add. The method is to right-click in the “Advanced” item, select “New → DWORD (32-bit) value” in the menu, and then modify.

005

Next, locate the “HKEY_CURRENT_USERSOFTWAREMicrosoftWindowsCurrentVersionExplorerTaskband” item in the Registry Editor.

006

At this point, in the right window of the “Taskband” item, click the right mouse button and select “New → DWORD (32-bit) Value”, and name it “NumThumbnails”.

007

The default value of “NumThumbnails” item should be 0, you can double-click the left mouse button to open the edit window to confirm that there is no problem, save and close the Registry Editor, and then restart the computer. Later when the mouse cursor moves to the taskbar application hover, you will find that the preview window is no longer, if the computer configuration is low, you should also find that the process will no longer have the problem of lag.
