- Type in Services in Windows search and press Enter.
- Scroll down to locate Background Intelligent Transfer Service (BITS).
- If it is already running, right-click and pick Restart.
- If the service is not running, double-click it, select Automatic under the Startup type from the drop-down menu.

Fix 2. Run the troubleshooter

Fix 3. Clean your disk from junk
Insufficient disk space may result in updates failing. You can clean your system by using the Disk Cleanup function:

Fix 4. Disable security or other software
Windows updates, such as KB5025221, may fail to install due to conflicts with third-party security software, firewall settings, or VPN software. These programs can block or interfere with the update process, flag update files as threats, block communication with Windows Update servers, or alter network configurations. Configuring, updating, or temporarily disabling these third-party programs may be necessary to allow successful Windows update installations.
Fix 5. Repair corrupted files
- Type cmd in Windows search.
- Right-click on Command Prompt and pick Run as administrator.
- When User Account Control shows up, click Yes.
- Use the following command lines, pressing Enter after each:

DISM /Online /Cleanup-Image /RestoreHealth
- Restart your system.
Fix 6. Install the update manually
If KB5025221 keeps failing, you can try installing it manually from the official Microsoft website:
- Open your web browser and navigate to the Microsoft Update Catalog.
- In the search box, enter the KB number of the update that failed to install.
- Locate the correct version of the update for your operating system by checking your System type (Right-click on Start and select System. Under Device specifications, check the System type).
- Click on Download and follow the prompts to complete the process.
- Once the update is installed, reboot your device.
Fix 7. Use Media Creation Tool
If the previously mentioned methods do not resolve the issue, an alternative approach is to use the Media Creation Tool. Prior to proceeding with the update, it is important to disconnect any unnecessary external devices, such as printers or USB flash drives. Also, uninstalling third-party security applications that may interfere with the update process is advised.

Don’t pay ransomware authors – use alternative data recovery options
Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files – Data Recovery Pro.
