Error code 0x80040507

[Rob Langford]

After exeriencing some print issues with Quickbooks pro 2010, running in XP, I was prompted to upgrade to XP SP3 and have been having a lot of issues. Xp under parallels crashes regulary, and in OS I can't reckognize USB ports until I quit parallels. Now I cannot start XP, and get the following message "Some system files are missing or damaged. You cannot log on at this time. Please use your installation CD to re-install or repair windows. Error code 0x80040507"

I do not want to lose all my data under parallels.

Please help.

You can try the steps below:
1. Click Start and start typing on your keyboard for "services.msc"
2. In your search results "services.msc" should show up. Open it with a click.
3. A new window will open containing all Windows services on your system.
4. Search for "Windows Update"
5. Right-click the "Windows Update" and then click Stop.

We will now clean the Windows Update temporary cache folder:
1. Hold your windows-key pressed and hit "R" key simultanous.
2. A small new windows will appear.
3. Type %windir%\SoftwareDistribution\DataStore in this new window and click OK.
4. This will open Windows Explorer on the correct location.
5. Delete all contents of this folder. (Hint: Use Ctrl + A to select all files and folders)

Now we will start the Windows Update Service again:
1. Switch back to the windows Services.
2. Locate Windows Update.
3. Right-click on it and choose Start.
