If your Windows product is showing wrong here we are at whatever reason, here are a few simple yet effective steps you can follow to repair the wrong time issue as quickly as possible in Windows 10.

Before following the below steps, restart your system. Oftentimes, an easy restart will fix lots of problems, including incorrect time. Also, the below discussed fixes will work on Windows 7 and Windows 8 too.

1]. See if Windows Time Service is Running

The first and foremost thing you should do is check if the Windows time services are running. If the time services are not running or stopped, Windows may show the wrong time as it cannot update it accurately.

1. First, press Win + R, type services.msc and click on the "Ok" button. You can also look for exactly the same in the start menu.

2. Within the Services window, scroll down, find "Windows Time" service, right-click on it and choose "Properties".

Next, select "Automatic" in the drop-down menu next to "Startup type" and then click the "Apply" and "Ok" buttons in order to save changes.

4. Restart the body to use the alterations.

2]. Sync Time with Internet Time Server in Windows

Windows has a neat little feature that lets you sync the time using the internet from accurate and reliable sources like time.windows.com or time.nist.gov. This selection is enabled by default. As such, once you connect with the internet, Windows will correct the time automatically. Under certain circumstances, this feature could easily get disabled. In that case, you have to let the internet time sync feature.

1. Look for Settings in the start menu and open the Settings app. You may also click the "All Settings" button obtainable in the notification center.

2. In the Settings app, go to "Time & Language -> Region". On the right panel, find the "Additional date, time & regional settings" link and then click it.

3. The above action will open the user interface window. Here, click the "Set the time and date" link under Date and Time section.

4. Within the Date and Time window, visit the "Internet Time" tab and click on the "Change settings" button.

5. Now, choose the "Synchronize by having an Internet time server" checkbox, select time.windows.com or time.nist.gov from the dropdown menu and then click the "Update now" button. As soon as you click on the button, the time is going to be updated. Click on the "Ok" button to save changes.

6. Close other windows.

3]. Check Windows TimeZone Settings

Once the timezone is not right, the time won't be correct. Generally, Windows can automatically detect the timezone and hang it. However, it can be wrong sometimes or you might've changed it unintentionally. Follow these quick steps to change timezone towards the proper location in Windows 10.

4]. Set Time Manually

If the automatic Windows time is wrong, you can set time manually too. It's very easy to do.

1. Look for Settings within the start menu and open the Settings app. You can also click on the "All Settings" button obtainable in the notification center.

2. Within the Settings app, visit "Time & Language -> Date & Time" page. Around the right-panel, toggle the switch under "Set time automatically" to the "Off" position. Next, click on the "Change" button under "Change date and time" section.

3. As soon as you click the button, another window will open. Here, make use of the drop-down menus to set time and date. Once you are satisfied, hit the "Change" button to confirm the alterations.

5]. Dual-booting with Linux? Add RealTimeIsUniversal DWORD Value to repair Wrong Time in Windows

If you're dual booting Windows and Linux, you very well may wish to add the "RealTimeIsUniversal" value for your Registry. This is because Windows and Linux treat time differently.

Windows assumes whatever time your motherboard tells it as being the real time. On the other hand, Linux treats time told by your motherboard as UTC (Greenwich Mean Time) and off-sets it based on your timezone. As you have seen, every time you boot into the other OS, time will be modified which leads to the wrong or incorrect time.

I've already covered an in depth guide on how you are able to fix Windows and Linux showing another time. Follow that guide and you ought to be good.

6]. Re-sync Windows Time with PowerShell

Under certain situations, Windows gets confused and loses time synchronization. In those situations, you can re-sync time utilizing a simple PowerShell command.

1. Open the start menu, search for "PowerShell", right click on it and select "Run as Administrator" option. This action will open the PowerShell with admin rights.

2. In the blank PowerShell window, execute the below command. You can simply copy the command and right-click within the PowerShell window to paste it.

w32tm /resync

As soon as you execute the command, you should begin to see the outputs "Sending resync command to local computer" and "The command completed successfully". Do keep in mind when there isn't any web connection, the command won't execute successfully.

7]. Scan Your System, Could Be Virus or Malware Infection

Certain viruses and malware can change time without your notice or mess with Windows in such a way that it shows the incorrect time. So, if the above methods didn't fix the Windows wrong time issue, you might want to scan your system for just about any infection. You should use Windows Defender or third-party antivirus software like Avast or AVG to carry out a full system scan (not quick scan). Additionally, also employ the Malwarebytes to execute a full scan.

For the way big your hard disk drive is and just how many files you've, the scan can take a couple of hours. So, if possible, start the virus scan before you go to rest. That way, it will be completed before you decide to awaken and also you don't have to lose any productive time. If the scan finds any threats, follow the appropriate steps shown in your antivirus application to clean the system and find out if it fixes the issue.

8]. Check CMOS Battery

Every computer, even most laptops, has something called CMOS battery on its motherboard. One of the primary functions of the battery is to help the system keep track of the time even when it is switched off. This is the reason why even when you turned off and unplugged the pc for weeks at any given time, it may show the right time after restarting.

If the CMOS battery is faulty, it can no longer help the motherboard keep track of time. Consequently, every time you start your system you will see the incorrect time.

By simply resetting or replacing the CMOS battery, you are able to solve the incorrect time issue. More often than not, your motherboard manual should retain the steps to reset or switch the CMOS battery. If not, you will find a number of YouTube tutorials showing how you can do-it-yourself. Follow any one of those guides and you ought to be good.

On laptops, it's really a bit tricky. Generally, you'll find the state repair manual for your specific laptop model on the web. If you're comfortable repairing your own electronics, follow the repair manual. Otherwise, I'd recommend you to go to the first-party or third-party repair shop center.

That's all.
