When updating Windows, many users encounter various errors and failures. Whether due to corrupted files, network issues, or other technical reasons, Windows updates can sometimes fail to install correctly. This guide provides a complete overview of why Windows updates fail, how to create a USB for manual updating, and how to use specialized software for additional repair options.
Why did Windows Update fail?
In normal cases, users can use Settings to check update and perform Windows Update automatically.
But, sometimes, Windows Update when following problems happen:
1. Corrupted System Files
Over time, important system files may become corrupted, missing, or damaged, causing errors during the update process. These corrupted files can interrupt Windows' ability to complete an update.
2. Insufficient Disk Space
Windows updates require a certain amount of free disk space to download and install. If the system drive is low on storage, the update will likely fail.
3. Incompatible Hardware or Drivers
Sometimes, Windows updates conflict with outdated or incompatible drivers, particularly graphics, network, or storage drivers. This incompatibility can prevent updates from completing successfully.
4. Network Connectivity Issues
A weak or intermittent internet connection can interrupt the download process, especially with larger updates.
5. Pending Reboots
Occasionally, updates are stalled because a previous update requires a restart before new updates can be applied. Pending updates often queue up, leading to installation errors if left unresolved.
How to create a USB for Windows Update repair via Windows Media Creation Tool
For cases where typical troubleshooting methods don’t work, creating a USB for manual Windows Update can be a lifesaver. Here’s how to make a Windows update USB and use it to repair or update your system.

Step 2. Run the Media Creation Tool and choose "Create installation media (USB flash drive, DVD, or ISO file) for another PC."
Step 3. Select your language, edition, and architecture (64-bit or 32-bit), then download the ISO file or create the installation media directly on the USB drive.
Step 5. Choose ”USB flash drive” and click “Next”.
Step 6. Choose your prepared USB drive from the list, then ”Next”.
When it's done, the tool will start to download the latest Windows 10 installation files to your device.
▌Stage 2. Set up PC to boot from USB
Step 1. Insert the USB drive into the computer you want to update or repair.
Step 2. Restart your computer and press the appropriate key to enter the BIOS or boot menu (this key is often F12, F10, or ESC).
Step 3. Change the boot order to ensure the USB drive is the primary boot device.
Step 4. Save the settings and restart your computer.
▌Stage 3. Update Windows manually from the USB
Once the computer boots from the USB, follow these steps.

Step 2. Select “Repair your computer” at the bottom-left corner.
Step 3. Go to Troubleshoot > Advanced Options > Startup Repair to fix common issues.
