A reboot will resolve many issues, but it's not necessary to shut your compute down each day. At the end of each day, we recommend locking your computer (Windows key + L), which keeps your work up and windows open.  You do not have to log out. After work on Fridays (or at the end of your week), shut your system down using the proper procedure - Windows key > Power > Shut Down. Reboot during the week (at the end of the day is a good time!) if your computer seems to be running slower than normal.
