Windows Update error 80246008

Get the System Update Readiness Tool (save it) and right-click on it and "Run as Administrator". Choose the right one for you:

• All supported x86-based (32-bit) versions of Windows 7
• All supported x64-based (64-bit) versions of Windows 7

Let it run/fix things.

Reboot.

Try updating.

If it is still failing, attempt this next:

Reset your Windows Update Components with this FixIt:
How do I reset Windows Update components?

Reboot.

Try updating.

If it still fails, try this...

1. Start an elevated command prompt.
   
2. Run the following commands hitting enter after each line:
   
   net stop wuauserv
   cd %systemroot%
   ren SoftwareDistribution SoftwareDistribution.old
   net start wuauserv
   
   
3. Reboot
   
4. Try updating.

**Important** The following issues occur when you do this:

• Updates that are currently downloaded but that have not yet been installed have to be downloaded again by using Windows Update or Microsoft Update.
• When you delete the Software Distribution folder, your download history is removed.
• If you currently receive updates from Microsoft Update and from Windows Update, you will have to re-select this option from the Windows Update Web site.

**Note** If the issue is resolved and you can successfully download and install updates, you can safely delete the SoftwareDistribution.old directory to recover disk space.

STILL failing? We have something else to try...

Reboot.
