Right click on the clock icon in the bottom right corner of your Windows 8 screen. When the options menu pops up, select ‘Adjust date / time.’ A new window will then appear. Click on the ‘Internet Time’ tab and then click ‘Change settings.’ From the next screen you can select the option ‘Synchronize with an Internet time server.’ Once the drop-down menu appears you can select the option ‘time.windows.com.’ After that’s complete, simply tell the system to ‘Update now.’
