So Did you used Windows Upgrade Asaistant tool to upgrade your Windows 7 PC to Windows 10? Did Windows Upgrade Assistant tool stuck at 99% while Installing? If your Answer is Yes then, you might want to use Windows Media Creation tool and see if the installation goes through.

This might not always work for users, but you can try it once if you haven’t tried it yet. I always prefer to use Media Creation tool to Upgrade my and friend’s System. Also, it allows you to Download ISO so that you can have Windows 10 in a Flash Drive and use it anytime you want.

Method 2: Stop Windows Update Service.

This is the Method I would Personally Recommend you to Perform First of all. It Involves stopping Windows Update Service so that don’t conflict with Upgrading process. Windows Update service Runs in background and can come in way of Upgrading just when its about to finish.

I Have seen lot of users fixing this Windows 10 Upgrade Stuck at 99% issue by just stopping Windows Update Service. So let’s see how it is done. I am assuming you have Upgrade Assistant tool open which is stuck at 99%.

Step 1: Open RUN by Pressing Windows + R key.
Step 2: Type Services.msc in Run and hit Enter. This will open the list of Windows Services. Alternatively, You can Click on Start and search for Services.msc.

Step 3: You will see the list of Services just like above picture, Now Scroll Down and Search for Windows Update and Double click on it.

Step 4: Now you have Opened Properties of Windows Update Service. Now, you need to Click on Stop and also Change Start up type to Manual.

Step 5: Click on Apply to make the changes. Close Services and wait for Windows 10 Upgrading Process to Complete.

In above 5 Steps, we just Stopped Windows Update services so that Our Windows 10 Upgrading goes through without any conflicts. This way we made sure that our Upgrading doesn’t Clash with updating service.

If Every thing is done right, You will now see Windows Installation being done smoothly. Within few minutes you will be able to see Windows 10.

Method 3: Install Pending Windows 7 Updates.

If Method 2 Don’t Work for you then you, must first try and install updates that are available for Windows 7. If you are trying to upgrade to Windows 10 without Installing Currently Available Updates for Windows 7, You may get to see the upgrade process getting stuck at 99%.

So first of all just go to Windows Update, Check for Updates and Install all of them which are available. Now Use Media Creation tool to Upgrade to Windows 10.

This time, you should Upgrade going through and within few minutes you will be able to see Windows 10 Start Screen.

Method 4: Play the Waiting Game.

So as a Last resort you can only wait for the update to go through. If all the above 3 methods fails to fix the upgrade process stuck at 99%. Then you should Wait for installation to complete.

We have seen Some Users that waited for a day or two to get rid of the issue. So now all you need to do is don’t allow your Computer to Sleep. Let the Upgrade Process start and Forget it for a day or Two.

If you are having an old PC or Slow Device, then this Process can take too much time. Some of the features might take hours to install. Mind you that you should first perform above methods and then just wait for the completion.
