Windows 10 Update Assistant is a Windows update tool that can help you directly update your Windows to the latest version. However, this Update Assistant can face several glitches. For example, imagine leaving your laptop to finish updating overnight using the Windows 10 Update Assistant application. Before sleeping, your update progress is about 97%.

In this situation, frustration and concern might set in. But you don't need to worry since we've got you covered with nine effective solutions to fix this challenging problem in your computer.
When the Windows 10 Update Assistant gets stuck at 99%, it can be associated with several factors. Here are some possible causes for this issue:
❌Network issues: Slow or unstable internet connections might cause the Update Assistant to hang at 99% as it struggles to download the final components of the update. Network interruptions during the update process can also lead to this problem.
⚠️Corrupted system files: Existing system file corruption or errors can interfere with the update process. The Update Assistant may encounter difficulties replacing or modifying these files, causing them to hang at 99%.

Since Windows Update entails drivers within its domain, they might be a potential cause of the issue. When too many outdated peripheral devices are connected, it can disrupt the upgrade process.
As an initial troubleshooting step, it's advisable to disconnect all peripheral devices from your USB ports. This also includes any additional peripherals like USB-C SD card readers. Naturally, your mouse and keyboard can be left connected.
Once the procedure is completed successfully, you can gradually reconnect your devices, dealing with drivers at a later stage. This would also be a suitable time to update your drivers since it's an essential measure to ensure your PC operates smoothly.
If the problem of the Windows 10 Update Assistant being stuck at 99% persists, it's worth attempting the update again, this time without any peripheral devices connected.

Windows provides various in-built troubleshooters designed to address issues on your device.
Among these, the Windows Update troubleshooter is a valuable tool to resolve problems that may arise while updating your system.
Here's how to utilize the Windows Update troubleshooter on Windows 10:
Step 1. Tap "Windows + I" to launch the "Settings" app.
Step 2. From the left-hand menu, locate and click on "Troubleshoot".
Step 3. Click the "Additional troubleshooters" link on the right panel to access additional troubleshooters.
Step 4. You'll be presented with a new page. Under "Get up and running", select "Windows Update".
Step 5. Following this, go ahead and click on the "Run the troubleshooter" button. This will activate the tool, allowing it to identify and fix any update-related issues on your device.
Several users have reported resolving this problem by temporarily turning off their internet connection. If the previously mentioned solutions prove ineffective, you can attempt this approach.
You may disconnect the Ethernet cable, deactivate your Wi-Fi connection, and carefully monitor the update process for any alterations.
If the main cause lies in the internet connection, disabling it should bring noticeable changes during the update process.
Despite the effectiveness of Windows Defender as a security tool, most users prefer using third-party antivirus software for various valid reasons.
However, it's worth noting that some third-party anti-malware solutions can occasionally disrupt the system. In some instances, they might even prevent the upgrade process.
You don't have to stop using third-party antivirus software in favor of Windows Defender. However, one possible approach is temporarily disabling real-time protection until the upgrade installation is complete or uninstalling it completely.
To activate System Restore on your Windows 10 system, follow these steps:
Step 1. Launch "Start".
Step 2. In the search bar, input Create a restore point and choose the top result to open the "System Properties" page.
Step 3. Within the "Protection Settings" section, designate your primary "System" drive.
Step 4. Click on the "Configure" button.
Step 5. After that, go to the "Turn on system protection" choice.
Step 6. Remember that Windows 10 can automatically manage storage space. However, you can fine-tune this under the "Disk Space Usage" section using a slider to specify the storage allocated for recovery.
Additionally, there's a "Delete" button for removing all System Restore points, which can be handy for freeing up space or starting fresh with the recovery feature.
Step 7. Click "Apply". Finally, click "OK".
After completing these steps, your system will automatically generate restore points whenever new updates or specific system modifications are made.
Note that System Restore doesn't activate by default for all drives. If your computer is connected to multiple drives, you must manually enable protection for each.
Another method for upgrading your computer involves using Microsoft's official Media Creation tool. This tool serves the purpose of downloading the operating system and facilitating its installation on your system.
To apply this approach, you should start by downloading the Media Creation tool and proceed with the installation on your PC. After launching the tool, select the "Upgrade this PC now" option, which will take care of the rest for you.
