How to install updates through CMD

Open Command Prompt as Administrator.

To install an .msu update package, run Wusa.exe together with the full path of the file.

For example, if the windows10.0-kb4020821-x64_f864406d91f9c5ded327a3690c3ff000248f9eab.msu file is in the C:\Users\V!kaS\Downloads folder, type the following command at a command prompt to install the update package:

wusa.exe C:\Users\V!kaS\Downloads\windows10.0-kb4020821-x64_f864406d91f9c5ded327a3690c3ff000248f9eab.msu

                                                                  Download
To run Wusa.exe in quiet mode without user interaction, use the /quiet switch. When the tool runs in quiet mode, it runs without user interaction. The computer restarts if it is required.

For example, if the windows10.0-kb4020821-x64_f864406d91f9c5ded327a3690c3ff000248f9eab.msu file is in the C:\Users\V!kaS\Downloads folder, type the following command at a command prompt to install the update package without user interaction:

wusa.exe C:\Users\V!kaS\Downloads\windows10.0-kb4020821-x64_f864406d91f9c5ded327a3690c3ff000248f9eab.msu /quiet

Note: When you use this switch, the Microsoft Software License Terms do not appear.

To prevent Wusa.exe from restarting the computer, use the /norestart switch. The /norestart switch is ignored if the /quiet switch is not present. If you run Wusa.exe together with these two switches, you must manually restart the operating system after the installation is complete if the installation requires that you restart the computer.

For example, if the windows10.0-kb4020821-x64_f864406d91f9c5ded327a3690c3ff000248f9eab.msu file is in the C:\Users\V!kaS\Downloads folder, type the following command at a command prompt to install the update package:

wusa.exe C:\Users\V!kaS\Downloads\windows10.0-kb4020821-x64_f864406d91f9c5ded327a3690c3ff000248f9eab.msu /quiet /norestart

How to install Windows 10 Creators update Manually

1. 
   

• Download the Media Creation Tool from the Microsoft support website. 
• Double-click the MediaCreationTool.exe file to start the process.
• Click Accept to agree to the terms.

Starting the Upgrade

Double click on ISO to mount it then start the upgrade. If you are installing from a DVD or USB thumb drive, insert or connect it, then click the on screen notification. If setup does not start automatically, click Start > File Explorer > This PC > open the drive containing the Windows 10 setup files, then double click Setup.exe.
                                   
                                            Download

1. 
   Click Run setup.exe
   
   Wait while setup is initialized. 
   
   You can select download and install any important updates before upgrading. This is recommended since it can help to ensure a smooth upgrade. If you are not connected to the Internet, select the Not right now radio box instead. Click Next.
   
   Wait while Windows 10 setup checks your system for compatibility issues. 
   
   Accept the End User License Agreement. 
   
   Wait while Windows 10 setup does one final check to ensure your system is ready. 
   
   Windows 10 setup will check if you have enough disk space.
   
   Please note, you have the option of choosing what you would like to keep, which includes personal files, apps and settings. 
   
   If you want to perform a new install or just keep your files click Change what to keep. Once you have chosen the desired options, click Install to begin.
   
   This will be your screen for a little while. During the installation, your computer will restart several times.
   
   After the first restart, Windows 10 setup will resume. You will notice the setup experience has once again been refined from the previous animated circle. This will be your screen for a while. When complete, Windows 10 setup will restart automatically.
