0x80070020 update error

Back to Top

When you try to download an update from the Windows Update Web site or from the Microsoft Update Web site while you are using Windows XP or Windows Vista, you  receive the following error message:
  • "0x80070020."
  • Additionally, you may receive the following error message.

    "The process cannot access the file because it is being used by another process. "

Cause: This problem may occur because of a timing issue that occurs when you try to download the update. Or, it can occur if a program is interfering with the automatic update process. For example, antivirus programs that use real-time scanning can interfere with the automatic update process.

How to fix?

Problems with installing Windows updates can occur when Windows Update and another program both try to access the same file. Although many programs can cause this issue to occur, the most common are antivirus programs and programs that perform real-time backups of system files.

To resolve the pc error, follow methods:

  • Method 1: Restart your computer, and install the updates

    Close all programs that are running, and then restart your computer. After the computer has started successfully, look in the notification area in the lower-right side of the screen for the Windows Update icon. If the icon is available, double-click it, and then install any available updates. If icon is not available, click Start, click All Programs, and then select Windows Update from the list of applications.

  • Method 2: Start the computer in safe mode with network support, and then install the updates

    To start your computer in safe mode in Windows Vista or in Windows Server 2008, follow these steps:

    1> Click Start, and then type msconfig in the Start Search box.

    2> In the Programs section, click Msconfig.exe.

    3> In the System Configuration dialog box, click the Boot tab.

    4> Click to select the Safe boot check box, click Network, and then click OK.

    Note The Safe mode with networking option does not work for computers that have dial-up connections to the Internet. You cannot use safe mode with networking support because modem drivers and PC Card drivers do not load in safe mode with networking support.

    5> In the System Configuration dialog box, click Restart. The computer restarts in "Safe mode with networking" mode.

    6> Install the updates.

    7> After the updates are installed, restart your computer in safe mode, and then click to clear the Safe boot check box.

    8> In the System Configuration dialog box, click Restart. This option starts Windows in its normal mode.
