Windows 10 has many improvements over its predecessors. One of the features is fast startup. Windows 10 has technology that help Windows start faster than previous version of Windows. However, this feature can be a problem when Windows or a program acts up. If you turn the computer off then back on you will often end up with the same problem as before because of the way the fast startup feature works. However, if you restart the computer instead of shutting it down and turning it back on, Windows 10 will skip the fast startup feature. This takes longer but often clears the problem, just like it did in earlier versions of Windows.
