OS Deployment Task Sequence failed at Capture User Files and Settings task
You’re deploying an operating system using SCCM with USMT 4.0, you kick off the task sequence. Everything works fine till the point of the Capture User Files and Settings task. And then it failed with the error below. Error code (0x8007001B).
This could because you had a specific security update that is causing the problem. The solution? Remove the KB974571 from the computer USMT is trying to backup date and then try again.
Alternatively there is a hotfix from Microsoft to address this issue. Download this hotfix and apply this on the Configuration Manager SP1 or SP2 server as well as to all your SCCM managed clients. Happy trying.
