1.Go to My Computer by typing it in the Search bar or simply looking for it in the Start menu. Go to Local Disk (C:) then click on $WINDOWS.~BT folder. Delete all the files within the folder.

2.Now, go to Local Disk (C:) then click on the Windows folder. Then, click on SoftwareDistribution folder. Find the Download folder. Delete all the files within this folder. Do not just simply delete the folder but take time to manually delete the files inside it.

3.Launch Command Prompt by typing cmd in the Search bar or Run. Right-click on the icon and select Run as administrator to run Command Prompt with administrative privileges. User Account Control window will pop asking Do you want to allow the following program to make changes to this computer? Click on the Yes button.

4.Command Prompt (Admin) window will now open. In the command line, type in wuauclt.exe/updatenow then press on Enter.

Step 2. Use Registry Editor

Before you try to solve this issue with this method, we highly recommend you create a backup of your system registry first.

This can be done by following the instructions below:

1.Press Windows + R key on your keyboard to launch Run.

2.In the Run box, type in regedit and hit Enter or select OK to launch Registry Editor.

4.Export Registry File will ask you where you want to save the registry key. Select the folder (you may create a new folder and rename it if you wish) and hit the Save button.

Now that you’ve already made the backup, let’s proceed. In this method, we’re going to make use of Registry Editor. It is a built-in tool created by Windows to allow users to manipulate settings of their operating system. These might not be accessible by just simply going to the Settings app. This particular tool dives into the deeper inner working of your PC. Just carefully follow the instructions below to proceed.

1.Press Windows + R key on your keyboard to launch Run.

2.In the Run box, type in regedit and hit Enter or select OK to launch Registry Editor.

3.In the Registry Editor window, look for HKEY_LOCAL_MACHINE folder. Under this folder, look for SOFTWARE and click it. Then, find Microsoft folder. Now, click on Windows folder.

4.On the right-side of the window, make a right-click on the white space to open up a drop-down menu of properties. Select New and then choose DWORD (32-bit) Value.

5.You’ve now created a new file. Rename it to AllowOSUpgrade. Assign value data as 1. Click Hexadecimal as Base. Select OK to make the changes.
