Here's what I found from Microsoft Support Site. Keep in mind, this solution was to address border being too thick. So, try positive numbers instead:
**To change the Window border width, follow the steps below:**
1. Right-click the Windows key and select Run.
2. In the Run field, type regedit, and click OK.
3. Click Yes if prompted by UAC.
4. In regedit, navigate to the location: HKEY\_CURRENT\_USER\\Control Panel\\Desktop\\WindowMetrics
5. In the right pane of WindowMetrics, double click PaddedBorderWidth to modify it.
6. Type in a data value of 0 (zero) or between -1 to -1500, and click OK.
7. Close regedit.
8. Sign out and sign in with your user account to apply.
