How to change border width in Windows 8

Problem

Windows 8 displays the windows in Desktop mode with a pretty thick border. The Advanced Appearance Settings dialog which could be used to change the border width in Windows 7 does not seem to be present in Windows 8!

Solution

Fear not, these settings can be changed in the Registry in Windows 8. Open the Registry Editor and navigate to HKEY_CURRENT_USER\Control Panel\Desktop\WindowMetrics. The keys here that are related to the border width are BorderWidth and PaddedBorderWidth. The default value of BorderWidth is -15 and that of PaddedBorderWidth is -60. Change them to higher values to reduce the border width and vice versa. For example, I prefer to change both of them to 0 for a thinner border.
