1. Delete the Contents of the DataStore Folder

The DataStore folder in Windows is a log file that stores information about all the updates installed in the system. This folder is located in the SoftwareDistribution folder, which is a directory of update-related information in Windows.

In several cases, the underlying issue was caused due to the corrupt components of the DataStore folder, which were interfering with the system’s update process. An easy way to resolve this issue is by deleting the contents of this folder or removing the Data Store folder as a whole. Both methods are safe to execute.

We have described the steps for doing this below. However, if you do not want to delete the DataStore folder or its contents, you can also repair them. For that, follow the next method below.

1. Launch File Explorer and navigate to the following location below:
   C:\Windows\SoftwareDistribution
   
2. Locate theDataStore folder in the SoftwareDistribution folder and right-click on it.
3. ChooseDelete from the context menu.

2. Run System Scans

The next thing you can do is scan the system for potential issues. The best way to do this is by using built-in system utilities like the System File Checker and DISM.

The System File Checker (SFC) will scan the protected system files for inconsistencies. If it finds a file that is corrupt, SFC will replace it with its healthier cached counterpart. DISM, on the other hand, will repair the system image.

We will be using the Command Prompt to run these tools. Make sure you are logged into Windows as an administrator before proceeding:

Here is all that you need to do:

1. Open Command Prompt as an administrator (see how to run the Command Prompt as an administrator for instructions).
2. ClickYes in the User Account Control prompt.
3. In the Command Prompt window, type the command mentioned below and hitEnter .
   sfc /scannow
   
4. Wait for the command to execute, and then execute the following command:
   Dism /Online /Cleanup-Image /ScanHealth
   
5. Next, proceed with the following command:
   Dism /Online /Cleanup-Image /RestoreHealth
   
6. Once this command is executed, close the Command Prompt window and check if you can now download the targeted updates.

While you are at it, you can also run the Windows Update troubleshooter . This tool also works like the utilities we just described above. It will scan the system for errors and suggest you relevant fixes that can be applied using the troubleshooter as well.

3. Repair the Update Components

As we mentioned earlier, the update components can also deal with some kind of corruption, leading to the problem under discussion.

The good news is that repairing these components is quite simple, and we will also use the Command Prompt in this method. We recommend creating a restore point before you proceed. This will help you revert to the current system state in case something goes wrong during the execution of the method.

Once the restore point is created, follow these steps:

1. Open a Run dialog box (see how to open Windows Run to learn how).
2. Type cmd in the text field of Run and press Ctrl + Shift + Enter to open Command Prompt as an administrator.
3. ClickYes in the User Account Control prompt.
4. Once you are inside the Command Prompt, execute the commands below one by one:
   <code>net stop wuauserv net stop cryptSvc net stop bits net stop msiserver

``
5. Once all the services are stopped, execute the following commands. These will clear the update cache in the system:
<code>ren %systemroot%\softwaredistribution softwaredistribution.bak ren %systemroot%\system32\catroot2 catroot2.bak
``
6. Now, proceed with the following commands one by one to start the Windows update services again:
<code>net start wuauserv net start bits net start cryptsvc net start trustedinstaller net start appidsvc
