In Windows operating systems, there is a system clock that appears in the taskbar. Your computer uses it for program logs, scheduled tasks and document/file saving. If it seems like your PC clock consistently runs too fast, you can sync it with an online server that will keep it running at the right speed.

Log in to your computer, click on the time display on the far right side of your taskbar, and then click "Change data and time settings."
Open the "Internet Time" tab, then click "Change settings."
Select the check box for "Synchronize with an Internet time server," then select a server to which your clock can be in sync. (The default is "time.windows.com.")
Click "Update now" and "OK," then "Apply" and "OK." Your PC clock will now automatically sync with the server you chose, preventing it from running too fast.
