The Windows 10 Update Assistant is a Windows updating tool that helps you update Windows directly to the latest version. However, this update helper might run into some issues. For instance, imagine using the Windows 10 Update Assistant app to update your laptop overnight. You go to bed with your update progress at around 97%.

Yet, the next morning, you are greeted with an unwelcome sight: the update appears to be stuck at 99%, and has been for the last eight hours.

In such a situation, you might feel frustrated and worried. But fear not, for we have nine effective solutions to this computer conundrum.

Why does the Windows 10 Update Assistant get stuck at 99%?

When the Windows 10 Update Assistant gets stuck at 99%, it could be attributed to several factors. Here are some possible reasons behind this issue:

❌ Network Issue: A slow or unstable internet connection can cause the Update Assistant to get stuck at 99% while downloading the final components of the update. An interruption in the network during the update process can also lead to this issue.

Warning: Corrupted system files: If your existing system files are damaged or contain errors, this can interfere with the update process. The Update Assistant might have trouble replacing or modifying these files, leading to the update getting stuck at 99%.

Lack of disk space: If your computer doesn't have enough free space to accommodate the update, the installation may pause at 99%. Windows needs room to extract and store temporary files while updating. You can free up storage space by permanently deleting files on Windows 11.

Peripheral devices: Sometimes, a printer, external hard drive, or other peripheral can interfere with an update. Disconnecting any unnecessary peripherals might help resolve the issue.

Sometimes, you might see an error message that says, "We ran into a problem installing the updates, but we'll try again later. If you keep seeing this and want to search for info or contact support, it might help to know: (0x80080005)." Read on to fix the 0x80080005 error.

If your Windows 10 Update Assistant is stuck at 99%, don't worry. There are a few solutions that can help fix this issue:

Fix 1: Run Setup from the Media folder

Microsoft offers an official guide to address the annoyance of the Windows 10 Upgrade Assistant getting stuck at 99% during installation. The solution includes a series of steps to alleviate the issue:

Step 1: First, open File Explorer.

Step 2: Type C:\GetCurrent in the address bar and press Enter.

Step 3. Locate the “Media” folder and make sure it is visible. If not, go to the “View” tab and make sure the “Show hidden files, folders, or drives” checkbox is selected.

Click on "Show hidden files, folders, or drives".

Step 4. Now restart your Windows 10 computer.

5. Next, reopen File Explorer and type C:\$GetCurrent in the address bar, then hit Enter.

Step 6: Now copy the “Media” folder from the desktop to the C:\$GetCurrent folder.

Step 7: Double-click on "Setup" in the "Media" folder.

Step 8: Follow the on-screen instructions to begin the update process. On the “Get important updates” screen, select “No thanks,” and then click “Next.”

Select "Not right now" and click on "Next".

Step 9. It is critical to install all available updates at this point. Click the “Start” button, go to “Settings,” then “Update & Security,” and finally “Windows Update.” Here, select “Check for updates” to make sure your system is up to date.

Click on “Check for updates.”

Fix 2: Stop and restart the Windows Update service

Another solution is to restart the Windows Update service.

This process encompasses all the processes related to updating and should resolve the error. Here's how to do it:

Step 1: In the Windows search bar, type “services,” and open the Services app.

Find the "Windows Update" service.

Step 3: Right-click it, and select “Stop.” Now, repeat the process, but this time choose “Start.”

Right-click on “Windows Update,” and select “Start.”

Fix 3: Delete update cache in Safe Mode

Another effective way to resolve update issues is to manually clear the update cache. Here's how to do it:

Step 1. Hold the “Shift” key and select “Power” to start in Safe Mode.

Step 2. Next, go to "Troubleshoot" and then choose "Advanced options." From there, go to "Windows Startup Settings" and select "Restart."

Step 3: Choose “Safe Mode.”

Step 4. Next, you need to stop the Windows Update service. Press "Windows + X" keys together to open the menu and select "Command Prompt," then type in the following command:

5. To empty the “Software Distribution” folder, navigate to C:\Windows\SoftwareDistribution in File Explorer, and move its contents to an empty folder.

Step 6. Restart the Windows Update service using the following command:

Start the Windows Update service
Start the Background Intelligent Transfer Service

Fix 4: Disconnect External Devices before the Update

Since Windows updates include drivers within their domain, they can be a potential source of the problem. Having too many outdated peripherals connected might interfere with the upgrade process.

As a preliminary troubleshooting step, unplug all peripherals connected to the USB ports, including any extras like a USB-C SD card reader. Of course, you can keep your mouse and keyboard connected.

Once that's done, you can gradually reconnect your devices and deal with driver issues later. It's also a good time to update your drivers, as this is an important step in keeping your computer running smoothly.

If the Windows 10 Update Assistant getting stuck at 99% issue persists, it's worth trying to update again with no peripherals connected.

Fix 5: Run the Windows Update troubleshooter

Windows comes with various built-in troubleshooters designed to address issues on your device.

Among them, the Windows Update Troubleshooter is a useful tool that can help resolve issues that might occur while updating the system.

Here's how to use the Windows Update troubleshooter on Windows 10:

Step 1: Press the “Windows + I” keys to open the “Settings” app.

Step 2: From the left menu, find and click on “Troubleshooting.”

Click the “Other troubleshooters” link on the right pane to access other troubleshooters.

Step 4: You'll see a new page. Under “Get started,” click “Windows Update.”

Step 5. Next, click on the “Run the troubleshooter” button. This will initiate the tool to identify and fix any issues related to updates on your device.

Click Run the troubleshooter.

Solution 6: Temporarily disable your internet connection

Some users have solved this problem by temporarily disabling their Internet connection. If none of the above solutions work, you might want to try this.

You might try disconnecting the Ethernet cable, turning off Wi-Fi, and watching carefully for any changes during updates.

If the problem is mainly with your Internet connection, you should see a difference if you turn it off during the update.

Solution 7: Turn off any third-party antivirus software

While Windows Defender is an effective security tool, most users prefer to rely on third-party antivirus software for various legitimate reasons.

That said, it's worth noting that some third-party antivirus solutions can interfere with the system, and in some cases may even block the upgrade process.

You don't have to stop using a third-party antivirus to use Windows Defender. However, one possible way is to temporarily disable real-time protection, or uninstall it altogether, before you perform the upgrade.

Fix 8: Perform a System Restore

To enable System Restore on your Windows 10 system, follow these steps:

Step 1: Click the "Start" button.

Step 2: Type Create a restore point in the search bar, and then choose the top result to open the System Properties page.

Type "Create a restore point" in the search bar

Step 3: Under Protection Settings, specify your primary system drive.

Step 4: Tap the “Settings” button.

Step Five: Next, select the “Turn on system protection” option.

Step 6. Keep in mind that Windows 10 can manage storage space automatically, but you can fine-tune the amount of storage space reserved with the slider under Disk Space Used.

There is also a “Delete” button to remove all system restore points. This can be useful for freeing up disk space or starting fresh with the recovery feature.

Step 7: Click “Apply.” Finally, click “OK.”

After you do this, the system will automatically create a restore point whenever a new update is installed or specific changes are made to the system.

Note that System Restore is not turned on by default for all drives. If you have more than one drive connected to your computer, you must enable protection for each drive manually.

Fix 9: Use the Windows 10 Media Creation Tool

Another way to upgrade your PC is by using Microsoft's official Media Creation Tool, which downloads the operating system and helps you install it on your system.

To do this, download the Media Creation Tool and run it on your computer. When prompted, choose the option to “Upgrade this PC now,” and the rest of the process should be automatic.

Click on **Upgrade this PC now**.

Please note that this process may take some time to complete, so it is advised to be patient.
