If you mix your personal and professional data on the same PC, it's time to draw a line between the two. Create a separate user account for doing work on your home computer, and you'll minimize distractions and more easily find work files and applications when you need them.
To create a new user account in Windows 8, visit the Settings screen and click the Users tab (the second from the top). At the bottom, find the option to add a new user. Windows encourages you to use a Microsoft account for the new identity, but you can decline and create a local user instead.
