The 0x800705b4 Windows Update error can appear when Windows takes too long to complete an update or when the update process becomes stuck. You may see this error while checking for updates, downloading an update, or installing a Windows feature update.
The error can be frustrating because Windows may repeatedly try to install the same update without completing it. Fortunately, there are several practical solutions you can try. Restarting the computer, checking Windows Update services, running built-in troubleshooters, repairing system files, and resetting Windows Update components can often help.
Before making advanced changes, make sure your computer is connected to a reliable internet connection and that you have enough free storage space.
What Is the 0x800705b4 Windows Update Error?
The 0x800705b4 Windows Update error generally indicates that an operation timed out. In simple terms, Windows was waiting for an update-related task to finish, but the process did not complete within the expected time.
Several things can contribute to this problem, including corrupted update files, Windows Update service problems, damaged system files, security software interference, or temporary Microsoft server and network issues.
The error does not necessarily mean that your Windows installation is permanently damaged. In many cases, restarting the update process or repairing the Windows Update components can resolve it.
Common Causes of Error 0x800705b4
Understanding the possible cause can help you choose the right solution.
| Possible Cause | What It Can Do |
|---|---|
| Corrupted update files | Prevent an update from installing correctly |
| Windows Update service issue | Stop Windows from processing updates |
| Damaged system files | Cause update operations to fail |
| Antivirus interference | Block certain update activities |
| Internet problems | Interrupt downloading or verification |
| Low storage | Prevent updates from being installed |
| Previous failed update | Leave incomplete update files |
| Background software | Interfere with the update process |
Restart Your Windows PC
The first solution for the 0x800705b4 Windows Update error is surprisingly simple: restart your computer.
A restart can clear temporary system processes and refresh Windows services. After restarting, open Settings > Windows Update and check for updates again.
If the update installs successfully after the restart, you do not need to perform more advanced troubleshooting.
Check Your Internet Connection
Windows Update needs a stable internet connection to download update files.
If your internet connection is unstable, restart your router or connect your computer to another reliable network. Avoid interrupting the connection while Windows is downloading or installing an update.
You can also temporarily disconnect from a VPN if you are using one. Some network configurations can interfere with update downloads.
Run Windows Update Troubleshooter
Windows includes troubleshooting tools designed to identify common update problems.
Open Settings and go to System > Troubleshoot > Other troubleshooters. Find Windows Update and select Run.
Follow the instructions displayed by Windows. The troubleshooter may detect problems with update services or configuration and recommend a repair.
The exact location of troubleshooting options can vary slightly between Windows versions.

Check Windows Update Services
The Windows Update service needs to be running correctly.
Press Windows + R, type services.msc, and press Enter.
Find Windows Update in the list. Check whether the service is running. You can right-click it and choose Restart if the option is available.
You can also check related services such as Background Intelligent Transfer Service (BITS). These services help Windows download and process updates.
After restarting the services, return to Windows Update and check again.
Run System File Checker
Damaged Windows system files can sometimes cause update problems. Windows provides the System File Checker (SFC) tool to scan and repair protected system files.
Open Command Prompt as administrator and run:
sfc /scannow
Wait for the scan to finish. Do not close the Command Prompt while the process is running.
If Windows finds corrupted files, it will attempt to repair them. Restart the computer afterward and check Windows Update again.
Use DISM to Repair Windows
If SFC does not solve the problem, you can also use the Deployment Image Servicing and Management tool, commonly called DISM.
Open Command Prompt as administrator and run:
DISM /Online /Cleanup-Image /RestoreHealth
The process may take some time. Allow it to finish completely.
Once it has completed, restart your PC and try Windows Update again.
Using SFC and DISM together can be useful when Windows system components have become corrupted.
Reset Windows Update Components
If the 0x800705b4 Windows Update error continues, resetting the Windows Update components may help.
Windows stores temporary update files in specific folders. If these files become corrupted, Windows Update may repeatedly fail.
Advanced users can stop Windows Update-related services, rename the update cache folders, and restart the services. Windows will then create fresh folders when the update process runs again.
This method involves using administrative Command Prompt commands, so it is important to enter each command correctly. If you are not comfortable with advanced troubleshooting, try the simpler solutions first.
Temporarily Check Security Software
Third-party antivirus or security software can sometimes interfere with Windows Update.
If you recently installed or changed security software and the update problem started afterward, check its settings. Do not permanently disable your security protection just to install an update.
Instead, follow the security software manufacturer’s recommended method for troubleshooting update compatibility.
Windows Security itself should generally remain enabled while troubleshooting.
Make Sure You Have Enough Storage
Large Windows updates may require additional free storage space.
Open Settings > System > Storage and check how much space is available on your Windows drive.
If the drive is almost full, remove unnecessary temporary files, old downloads, or applications you no longer use. Windows also provides storage-management options that can help free up space.
After creating enough free space, restart the computer and check for updates again.
Disconnect Unnecessary USB Devices
In some situations, external hardware can complicate the update process.
If you have unnecessary USB drives, external storage devices, printers, or other accessories connected, disconnect them temporarily.
Leave only the essential devices connected and restart the computer. Then try Windows Update again.
This is a simple troubleshooting step and does not change your Windows settings.
Final Thought
The 0x800705b4 Windows Update error is usually related to a timeout during the update process rather than a permanent Windows problem. Start with simple fixes such as restarting your PC, checking your connection, and running the Windows Update troubleshooter. If the error remains, SFC, DISM, service checks, and Windows Update component repairs provide additional options.
