The following steps should help you solve the problem:
Perform clean boot and install all the updates manually. You can use the help of :https://support.microsoft.com/en-us/help/929135/how-to-perform-a-clean-boot-in-windows to clean boot. Keep in mind to cross check if the computer is set to start as usual.
Alternatively, you can also try to turn off “User Account Control “ just temporarily and then try installing the updates. After installing the updates turn on the “ user account controls “. The following link will help you to turn user control on or off

If you have a problem updating your Windows 7, check if you are using Service Pack 1. If your Windows 7 is not using any Service Pack, it would be better to update it to Service Pack 1. Visit Windows 7 SP1 [KB976932] then download the Service Pack 1 update. Once downloaded, run the installer to update your system to Windows 7 Service Pack 1.
Aside from doing the methods suggested in the previous 2 posts, try using the Windows Update Troubleshooter. To do this, click Start, Control Panel, and then type without quotes “troubleshooter” in the search box. In the search result, click Troubleshooting. In “System and Security”, select “Fix problems with Windows Update” and then follow the instructions.
Another way is to reset the Windows Update components. To try this, visit How to reset Windows Update components then click “Run now” in Microsoft Fix it utility. This will automatically reset the Windows Update components. Please make sure to click on the right Microsoft Fix it utility because there are 2 utilities available.
The first is for Windows 7, Windows 8, and Windows 8.1. The second utility which is located below the first one is for Windows XP and Windows Vista. See image.
Also, if you don’t want to use the tool, you can reset the Windows Update components manually. The instructions are displayed just below the second utility.
