3. CMOS battery getting weak

One of the most likely reasons the Windows 10 computer is not showing a stable time is that the CMOS battery might have passed its prime. If you’re affected, do the following

If you aren’t too adept with the hardware side of your PC, CMOS stands for Complementary Metal Oxide Semiconductor and the said battery is placed on the computer’s motherboard, which in turn powers the CMOS chips also placed on the motherboard. The chip contains vital information concerning the computer’s system configuration, which includes the date and time info as well.

The battery ensures the chip can hold on to the information even when the computer is turned off or is not connected to a power source. This way, the next time you turn the PC on, you will find everything spot on and up-to-date.

However, the battery can wear out which can be either as part of the natural weathering process or due to some defect. And this is when the computer can start showing erroneous time. The PC getting shut down on its own is also among the more serious symptoms that points to the CMOS battery being the culprit.

Unfortunately, changing the battery requires a fair bit of hardware repairing skills. Hence its best to rely on your local hardware expert to get the CMOS battery replaced or you can get in touch with the company support staff to get the job done.

4. Tweaking Services.msc setting

Making Windows Time to start up automatically each time your PC starts can also be effective to deal with time issues on Windows 10. here is how you do it.

  • Press Windows key + R on your keyboard simultaneously to launch the Run dialog box.
  • Types Services.msc and press enter to launch the Service dialog box.
  • In the Services dialog box, locate and right click on Windows Time and select Properties.
  • In the Windows Time Properties dialog box, set Startup type to automatic.
  • Also, ensure the Service status is Start. If it isn’t, Start the service.
  • Click on Apply > OK.

This is it. If Windows 10 time keeps changing, the above methods should set things right.
