We have seen how to uninstall or disable Java on various browsers on a Windows machine yesterday. This article will tell you how to disable Java or change its permissions using the Group Policy Editor in Windows 7 or Windows 8.

Disable Java using Group Policy

If you Enable this policy setting, you can choose options from the drop-down box. Custom, to control permissions settings individually.

  • Low Safety enables applets to perform all operations.
  • Medium Safety enables applets to run in their sandbox, plus capabilities like scratch space and user-controlled file I/O.

    Or you could simply go to Control Panel/Java/Security and change the setting!

    Anybody seen how to fix a computer that keeps disabling its Java in the Group Policy Editor? Have re-enabled and set to Medium Safety multiple times.
