Steps to Fix the Windows Vista 0x80070020 Backup Error

The 0x80070020 error often shows when you either try and back up Windows Vista or update your system. This error is normally caused by a program interfering with the backup / update process, making your system unable to write & access the files it needs to run.

Fortunately, this error is caused by a small number of acute issues which can be fixed by following the steps.

The 0x80070020 error normally shows like this:

* Error: 0×80070020 - The process cannot access the file because it is being used by another process

To fix this error, you should look to install the updates / backup in safe mode (where no programs will interfere with the process) and then create 'exceptions' in your Firewall to allow Vista to use the files it needs. You should also clean out viruses and repair the registry.

The first step to fix the 0x80070020 error is to restart your computer into "Safe Mode With Networking" and then install the updates through that. Safe mode is a part of Windows that Microsoft introduced to load up Windows without any of the interfering programs / drivers that often cause problems. This means that if you restart your PC and load it up with Safe Mode with Networking, you should be able to process the updates you need securely.

You should also look to clean out any viruses from your computer by using a virus scanner. Most people have these installed, but if you don't, it's advisable that you get one to make your computer better able to deal with the various issues that stop it from functioning properly. Viruses often cause errors like the 0x80070020 error as they attach themselves onto your system and then corrupt all sorts of files.

It's also recommended that you clean out the 'registry' of your PC. This is important for the 0x80070020 error because the registry is one of the most important parts of Windows - storing vital settings and options for your PC. Everything from your most recent files to your website passwords are kept in this database, making your computer run with all sorts of errors and problems. One of the main reasons why the 0x80070020 error shows is because the registry is constantly trying to be accessed by various Windows programs, and is therefore using a lot of the files that your Windows Update wants to use as well. To make sure this is not causing any of the issues on your PC, it's recommended that you use a 'registry cleaner' program to scan through this database and fix all the errors inside it.
