Time Synchronization Failed on Windows 11: 9 Ways to Fix it

If your PC isn’t set with the correct date and time, then you will face multiple system-related problems.

Notably, several tasks on your PC will be hampered if the time is not synced or if the time isn’t set correctly.

For instance, if you have downloaded or saved a file on your PC, due to an incorrect time, the file information will have adulterated information. Since it is the system clock that your PC uses to add timestamps to your files, keeping the correct time and date is important.

Software or updates also rely on internet-based authorized time, and if there is an incorrect time set on your PC, then your PC may reject those updates or install the software.

Usually, Windows 11 uses the NTP, i.e., Network Time Protocol, to connect your PC with the internet server to synchronize the clock. However, if it fails to do so, then you will experience the time synchronization failed on Windows 11 issue.

If you are also facing a time synchronization issue on Windows 11, and are looking for solutions, then you are in the right place.

Because in this guide, we will give you a list of some effective solutions, that have helped users fix the problem at hand. Let us check each solution out.
