How to Disable Changing Date and Time Formats

By Timothy Tibbetts

Windows offers the option to change your date and time formats. By using the Group Policy Editor or the Registry Editor, we can disable it so no one can change the date and time format.

Not everyone has the Group Policy Editor, so we can simplify the process using Registry files.

Download Disable Changing Date and Time Formats and extract the two files.

Double-click Disable Changing Date and Time Formats.reg or Enable Changing Date and Time Formats.reg (Default) to Enable or Disable Changing Date and Time Formats.

Click Yes when prompted by User Account Control.
Click Yes when prompted by Registry Editor.

Click OK when prompted by the Registry Editor.

This tweak is included as part of MajorGeeks Windows Tweaks.
