A user reports that every time a Windows 10 desktop is powered on, the clock shows January 1, 2002. After manually setting the correct date and time, the system operates normally until the next cold boot, when the incorrect date reappears and network logons fail. Which action will MOST likely provide a permanent fix for this time drift problem?
Run the sfc /scannow command to repair corrupted system files.
Update the Ethernet adapter driver to the latest signed version.
Install a new CR2032 battery on the system board.
Enable automatic daylight-saving time adjustment in Date and Time settings.
A depleted CMOS battery cannot maintain the motherboard's real-time clock when the system is powered off, so the BIOS reverts to its default date each time the PC starts. Replacing the CR2032 (or equivalent) battery allows the hardware clock to retain the correct time, eliminating the repeated drift. Running SFC, adjusting daylight-saving settings, or updating a NIC driver do not address a hardware clock that cannot hold its settings when the computer is unplugged.
