There is a particular Windows 10 issue that many users have complained about, namely the inability to change the time zone.
Some users received an error message when trying to change the time zone. Other users reported that the time zone returned to the initial form after restarting the PC.
I've had some problems with this machine before, and I thought it might be related. In the end, I had to try a couple of different solutions before I stopped getting the error message about not having permission.
The message that kept popping up was:
"Can't continue. You do not have permission to perform this task."
Methods to Change Date and Time in Windows
Method 1 - Safe Mode
You can try to change the date and time in Safe Mode. If you can change it here, you know it is a problem with a Windows startup item or service problem. You can then perform a clean boot of Windows to reduce the problem.
You can refer to this Microsoft article that details how to perform a clean boot in Windows:
Method 2 - System File Checker
The other thing you can do is to run the system file checker. If you have strange permission problems in Windows, it is probably some corruption of system files and settings. You can run SFC by opening a command prompt and typing the following command:
SFC / scannow
The system file checker will check all system files and replace any corrupted, modified, or damaged files.
Method 3 - Command line
You can change the date and time in Windows using the command line. Open a command prompt, type the word's date, and press Enter. You will be asked to enter a new date.
What happens with time? Pretty easy too. Just type in the speaking time, and you can also change the time:
Note that the time is in 24-hour format, and you can specify it in milliseconds. You will be able to change the time without opening an elevated command prompt. However, if you receive an error, try running the command prompt as Administrator.
Method 4 - Local Security Policy
If you receive an error message such as "The client does not have a required privilege" when you try to use the command prompt, go to Control Panel, Administrative Tools, Local Security Policy, and then navigate to Local Policy \ User Rights Assignment and Make sure to change the system time and Change the time zone privileges that are granted to administrators.
Note that if you are on a domain, you may be restricted by the group policy set by your company. If you are not in a domain and the administrators, do not have the two privileges shown above, adding the group to the security settings should fix the problem.
Method 5 - Windows Time Service
If you are still having trouble changing the date and time in Windows, go to Control Panel, Administrative Tools, and click Services. Go down to Windows Time and then right-click. Choose Properties. Click the Login tab and make sure it is set to This Account - Local Service.
The password fields should be filled in automatically, so there is no need to enter a password. Go ahead and restart the computer and see what happens.
Method 6 - Uninstall Third-Party Clock Apps
If you have a third-party clock manager or time programs, go ahead and uninstall them and see if that solves your problem with changing Windows date and time. Sometimes a conflict can occur, and a third-party program might prevent you from changing the time.
Hopefully, one of the above solutions fixes your problem. If not, post a comment here, and I'll try to help you. Enjoy!
