Method 1: Verifying The Minimum Requirement of The System For The Update

As mentioned prior maybe your system is just not compatible with the latest update, to verify this go to the official website of Microsoft.

Step 1: When the webpage interface opens you’ll find a highlighted button saying “Get anniversary update now”, click on it and a file will start to download.

Step 2: Wait for a while, run the program after the downloading is complete which will trigger your update assistant to open up, in this interface, you’ll find the button “update now”click this button.

Step 3: Just after clicking the button, you’ll be provided with a compatibility report, the incompatible components will be visible to you and if all the checkmarks are green then your system is compatible with Windows 10.

Step 4: If not there is not a problem lying it is just your PC is outdated. But it is safe to say that your system is compatible if the compatibility report is positive then here lies some other reason causing the error. so let’s move to the next fix.

Method 2: Resetting The WU Component Through An Automated Agent or Through an Elevated CMD Window

Before resetting the WU component it is convenient to use a simpler method to fix the issue with the Windows update service, this can be done with the help of Windows update troubleshooter tool:

Step 1: Download the Windows update troubleshooter tool from the official website for your Windows version.

Step 2: Run the troubleshooter tool to scan your system and fix automatic errors regarding Windows updates.

Step 3: No external command is required after the program fixes the error simply restart your system and check if the fix has worked.

If not we can go for resetting WU components which is discussed below;

There are two ways of resetting the Windows update component, the second one being a little bit tricky, let’s start with the easy one.

There is a gallery of scripts available for resetting the WU component, open your default browser and go straight to the Microsoft tech page. The script available here is universal and can go with all versions of Windows.

Step 1: Download the zip which is also known as the reset Windows update agent script.

Step 2: Wait till the download is completed and now extract the files to a folder.

Step 3: Find the file exe and click on it which will run the script. There are other files like ResetWUEng.cmd but you have to go through a whole set of manual instructions so it is better to let the script automatically reset the WU component.

Keep in mind to turn down other functions going on in the background because this script is going to reset all the components, running other files can again result in corrupted inoperable files.

Step 4: After the script has completed its work restart the PC, try the updating procedure and see if the fix has worked.

If the issue persists then we have to do this resetting manually using the command prompt (CMD), which brings up the next option.

Resetting Through an Elevated CMD Window:

The elevated CMD window allows you to execute commands with administrative privileges.

Step 1: Click Start and type cmd in the search box provided, hit enter.

Step 2: Right-click on the cmd.exe and choose run as an administrator” which will open up the user account control window.

Step 3: Click yes to run the Windows command prompt as an administrator.

Once inside the CMD interface, type in the following commands;

net stop wuauserv

net stop crypt

Svcnet stop bits

net stop msiserver

Step 4: These are commands to stop some Windows update services, after which you have to type in the below commands again in the interface.

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

ren C:\Windows\System32\catroot2 Catroot2.old

After entering each command hit enter to rename the software distribution in an attempt to terminate errors in the OS component.

Step 5: Now we are going to enable the services that we disabled priorly and we are going to do exactly what we did to disable them. so again type in the commands in order

net stop wuauserv

net stop crypt

Svcnet stop bits

net stop msiserver

This will enable this WU service, now we are one step away from fixing the error.

Step 6: Restart your PC, wait for a while let the system reach its optimal state, and now try resuming the updating procedure, if the error prompt still shows up, let’s move on to the next solution.

Method 3: Expanding The Reserved Partition

As explained in the reasons unavailability of partition space can be the problem, so to expand it we have to use a third-party tool, it is because it can’t be done using disk management.

If you try to do it with the disk management console you’ll find that the option extend has been grayed out stopping you from further proceeding, it is easy to find a third-party tool, we have a tool in handy called AOMEI partition assistant which can help you to do so.

Step 1: Download the freeware from a trusted website and install it.

Step 2: Right-click on the redundant partition where you’ll find the option Resize partition, click on it, it would almost need 400 MB to do so, select a drive say you selected drive C.

Step 3: An interface will pop out named “move and resize partition”, tick the checkbox ” I need to move this partition”, if you want to select space, you’ll find an option to do so, after that click

Step 4: In the main interface now you ll find the allocated space after the system reserved partition and before drive C.

Step 5: Now again right-click on the system reserved partition and select Resize partition.

Step 6: In the pop-out window, drag the slider bar rightward to extend System Reserved into unallocated space, now click OK to return to the main interface.

Step 7: Click apply in the next interface which would be the main interface and now the program would need a restart of your system in preOS mode.

After the system reboots try now updating the Windows and see if the error is still popping if so proceed through the next step.
