Does your version of Deep Freeze have an Advanced Configuration tab and a setting for "Allow User to Change Time" ? https://www.deepfreeze.com/webhelp/DFWC/DFWC_EN/index.html#page/EN/Chapter_EN.1.111.html From the link: "Allow user to change the clock – Select this option to allow Frozen users to adjust the system clock. Enable this feature during Daylight Savings to allow Windows to update the time automatically each season."Received on Wed Mar 25 2026 - 22:24:43 EDT
