Windows has Windows Update Troubleshooter, a pre-installed app that troubleshoots and automatically corrects update-related errors. To make use of this tool, search it on the Windows search box and run it. It will automatically repair any issues that are preventing a successful Windows 10/11 update.

While it is unlikely that your computer has a faulty USB port, it is not unheard of for some machines to suffer from this problem. Try switching between the different USB ports on your PC and see what happens. It might just resolve your problem.

3. Update the Drivers on Your PC

Drivers are what enables communication between the software and hardware components of your computer, and if they are out of date, misconfigured or corrupted, they might cause all sorts of problems, including the error code 0x8007045d.

To update drivers on Windows 10/11, take the following steps:

  1. On the Windows search box, type “device manager.” Alternatively, go to the Control Panel and click on Device Manager.

To be on the safe side, make sure that you update drivers for all of the devices that are listed on the Device Manager. It is highly recommended to keep all drivers up to date for optimal PC performance. After updating your drivers, see whether the issue has been resolved.

4. Repair Bad Sectors

Your computers disk drives are likely to blame for the error 0x8007045d. Disk drives are responsible for the read and write operations that allow apps to interact with the OS, which means that a faulty disk drive can cause data retrieval issues that could be the source of the error 0x8007045d.

You can troubleshoot disk problems with the help of the Command Prompt, and this is how to do it:

  1. Type “command prompt” on the Windows search box.
  2. Use administrator rights to run the Command Prompt app.

If the errors on your disk are repairable, Windows will automatically do the repairs for you, but be advised that some disk errors are irreversible, and you might have to buy a new disk drive.

5. Disable Your Antivirus Programs

Anti-virus software is generally meant to protect your PC from viruses and other malicious threats. An anti-virus program can, however, blunder and misidentify other software and even legitimate Windows processes as threats.

It is therefore advisable to disable or remove any anti-virus programs that you may have installed on your PC whenever a Windows error is detected. This, of course, should be done after a complete system scan has been carried out – let us not forget that viruses too can be responsible for all sorts of Windows errors.

How to go about disabling the anti-virus program on your computer will depend on the particular anti-virus program installed, but generally, all such programs have a disable button that is easy to find.

6. Enter Safe Mode

  3. You will be prompted to restart your system; click on the Restart button.
    After following the above steps, you can go ahead and try to install Windows 10/11 in Safe Mode to see whether you are still getting any errors.

7. System Restore

The system restore option allows you to return your computer to an earlier, functioning state. It does this by rolling back any changes – updates and software installations – made after a restore point. This option works best if your computer started experiencing errors after some changes were made.

Here is how to perform a system restore on Windows 10/11:

  1. On the Windows search box, type “create a restore point.”
  2. On the System Properties window, click on the System Restore button.
  3. Click the Next button.
  4. Select the Restore point that you want to use on your computer.
  5. Click the Scan for affected programs button to see the apps and updates that will be removed because they were installed after the restore point.
  6. Close the window and hit Finish. Windows will roll back any changes after the restore point.
    NB: This procedure only works if your computer already has a restore point.
