Hello DharmendraSingh7! Welcome to the Microsoft Community!
I'm Fran, a member of the Microsoft Community.
I want to help you with your problem, and I have been reviewing the Windows files and the error you indicate is because there may be some kind of error with some application that prevents it from installing correctly. Continuously, some types of Windows updates may get corrupted or not install correctly and as a result you may get the error code.
Other reasons may be some corruptions of files or disks in your Windows operating system that are causing the error code to appear.
I am going to give you some possible solutions to try to solve it:
Keep in mind that if none of the manual techniques works, there may be the possibility that a malware infection is responsible for the appearance of the Windows Update error 800B0109 and the problem can only be solved by completely resetting the computer.
Here are the steps:
Tip 1. Run a SFC system check.
As we have already mentioned, there may be some corrupt files related to Windows Update error 800B0109. In order to find out if there are any corrupted components on your system, you should run an SFC check using Command Prompt with administrator permissions. Proceed with these steps to complete the check:
-Go to the Windows bar and type "cmd".
-Execute the Command Prompt.
-Choose to Run as Administrator.
-After this, type sfc / scannow after the cursor.
-Press Enter and wait for the process to run.
-After this, restart the computer.
Tip 2. Run a disk diagnostic.
Windows Update error 800B0109 may also appear due to some types of corruption on the main disk. You can get the idea that this process is carried out through the Command Prompt as well:
-Go to Windows search and locate Command Prompt.
-Choose to Run it as Administrator.
-Then type chkdsk c: / f and hit the Enter key.
-Wait for the process to finish.
-Reboot your computer system and see if the error still persists.
Tip 3. Restart your computer in Safe Mode.
Use the steps below to start Windows in Safe Mode from the Windows desktop:
-Click on Start and type msconfig in the search box. Click on msconfig.
If prompted, enter the administrator password or confirmation.
The System Configuration tool will appear.
Click on the Startup tab.
Under Boot Options, click Safe Boot and select Minimum.
Click Apply and then OK.
When prompted, click Restart.
The computer starts in Safe Mode.
Tip 4. Apply a System Restore point.
You can also try disabling some changes in your Windows computer system by activating a previous restore point when certain modifications were not available. Complete the following steps as they can help you get rid of Windows Update error 800B0109 from your affected machine:
-Select the Windows key and type "Create a Restore point" in the search section.
-A new window will appear. -Here, choose System Protection.
After this, opt for System Restore and click Next.
Choose the earliest previous restore point and then tap Next.
Then click the Finish button and wait for the process to finish.
Restart your PC.
Once you've tried all the methods to fix Windows Update error 800B0109, some of them should have been helpful. However, if there is some other problem, for example a virus infection, manual steps may not be helpful in the repair process. To get rid of this error, you should use a trusted anti-malware program.
I hope that you solve it soon and that my help has been of some help to you. See you soon!
