Win7 system after the operation of the desktop right-click refresh response slow solution

In the Win7 system, we perform a lot of operations, back to the desktop, we will habitually right-click to refresh the desktop, but if the desktop refreshes very slow response, sometimes It even takes a dozen seconds, which is never a happy thing. What should I do? The method is as follows: 1. Press the WIN+R key at the same time to bring up the “Run” dialog box. Enter regedit, click OK to open the registry editor; 2, open the registry, then find the registry: HKEY_CLASSES_ROOT/Directory/Background/shellex/ContextMenuHandlers; 3, ContextMenuHandlers options below only leave the New option, the rest of the options are deleted In case of an error when deleting the item, you can directly determine it; 4. Finally, exit the registry editor and test the refresh effect. If it has not worked, you can restart the system and try again. Under normal circumstances, after setting by the above method, it can solve the problem that clicking the desktop right button refresh response is slow. At the same time, this tutorial also applies to the Win8 system.
