The system personalizes two cases of

1. The size of the window scroll bar can also be adjusted. When browsing a long page of a page, if there is no wheel mouse, dragging it will be very troublesome. We can modify the size of the scroll bar by ourselves. Run the Registry Editor and expand the "HKEY_CURRENT_USER\\Control Panel\\WindowMetrics" branch. The string values ​​"ScrollHeight" and "ScrollWidth" in the right window represent the height and width of the scroll bar. The default value is "-240". ", change to "-450" (do not change too large, otherwise affect the display effect of the page), restart the system to take effect.

2. Automatically refresh the window
When we add files in the folder, we often need to press F5 or click the right mouse button to select "Refresh" to see the new file. We can modify the registry to let the system automatically refresh the folder.

Run the registry editor, expand the "HKEY_LOCAL_MacHIN E\\System\\CurrentControlSet\\Control\\Update" branch, double-click "UpdateMede" in the right window, and change the key value to "0".
