If you are having trouble downloading or installing Windows 10 updates, it could be because of a common issue called “The Windows Update Assistant is stuck at ‘99%.'” Microsoft says that the issue happens when a PC is unable to connect to the Internet or a specific server during the installation process.

This problem occurs if there is no connection to the internet, or if there is a slow connection. If you receive a notification saying that your device needs to restart, do so immediately. You don’t want to lose access to your files while you wait around.

Microsoft recommends trying to use another browser like Chrome or Firefox, or even switching off Wi-Fi entirely and connecting via Ethernet cable.

You can also try disabling automatic updates temporarily to see if that helps. To disable automatic updates:

1. Uncheck Automatically check for updates

2. Click OK

The Windows 11/10 Update Assistant is stuck at 99%.

Microsoft has confirmed that Windows 10 version 1903, aka “Redstone 5,” is now rolling out to some PCs worldwide. However, it seems like there are some issues with the update, since many people are reporting that the Windows Update Assistant keeps showing up in the taskbar even though the installation is complete. Microsoft says that the issue is due to a bug in the update, and it expects to fix it soon. In the meantime, you can manually uninstall the update assistant app.

The good news is that this problem isn’t related to the recent BlueKeep vulnerability. If you’re running Windows 10 build 1803, you don’t need to worry about anything. You’ll receive KB4518582 automatically.

If you’re still seeing the Windows Update Assistant, here’s what you do next:

1. 2. Click the arrow button next to the Windows Update entry.

3. Select “Uninstall updates.”

4. Wait while the program uninstalls everything.

1] Wait

There are several ways to fix this problem. One of the easiest solutions is to wait. If you don’t use your computer often, try waiting for a few days. This might help. However, if you use your computer frequently, you might want to consider buying a new one.

Another solution is to restart the computer. You can do this by holding down the power button for 10 seconds and then turning the computer off. After you turn it back on, let it boot up normally.

If neither of those fixes work, you might need to contact the manufacturer of your laptop. They could replace your motherboard or memory card.
