When I run Windows Backup to save an image to the D: drive (have not tried other drives) I get 0x8007042d after it has run about 12% of the job.

The error says, "Windows Backup Troubleshooting options - Check your backup - The service could not start due to a logon failure - Backup location D: - error code 0x8007042d

After formatting D: the Backup function gave me the error when I tried to launch Backup, so at the moment I can't even start the backup. Error says, "Tha backup application could not start due to an internal error: The service did not start due to a logon failure. (0x8007042d)".

Checked Volume shadow copy service right after the launch failure and it shows the service is running.

I suspect the problem started when I installed or uninstalled Acronis backup software 2011 Home flavor. I removed all the Acronis entries in the registry, ran their fix utility, etc. No help.

I also have Carbonite which also makes an image of C: and saves it on the P: drive - paused Carbonite and Windows Backup still gives 0x8007042d.

Carbonite was installed about the time Acronis was uninstalled. Carbonite seems to be working fine.

At about the same time...I started noticing Not Responding events with a variety of programs. I have a 16gb ReadyBoost flash drive.

Thanks for your help!

Sounds like you may have done some damage to the Registry by manually deleting the Acronis entries.

If you have a restore point you can use that was before the Acronis installation then use that and try the backup again. If no restore points are available then run a Repair install.

System restore also failed, and I ran sfc /scannow and the first time I ran it it replaced some files, but the backup still failed. Running it now shows nothing wrong.

Tried a repair install, but that also did not help.

There is only twenty minutes between my suggestion to run a Repair Install and your last post, a Repair install takes a lot longer than twenty minutes or did you run this before my suggestion?

Does your Windows 7 installation disc include SP1? If it doesn't you can't use it to Repair your installed OS without first uninstalling SP1.

How far back did you go with System Restore, your saying it did not work which doesn't tell me much, did it run successfully?

The error code you are getting usually means there are missing system files so a System Restore should fix it but it needs to go back before the back up software was installed.

With all drives connected please open Disk Management and send a screenshot of it open to full screen so we can see how your partitions and drives are arranged.
