It focuses on that deployment workflow and two specific historical failure scenarios; it is not a general guide to every ImageX version or a claim of support for current Windows environments.
What ImageX is—and what it is not
Microsoft says, “The ImageX.exe tool ships as part of the Windows Automated Installation Kit (WAIK).” In the documented workflow, an installation prepared with Sysprep is captured from Windows PE and then applied to another computer. That is deployment imaging, not a complete backup of a computer.

Microsoft does not support ImageX as a full-system backup mechanism. It warns that ImageX can lose extended attributes, turn sparse files into non-sparse files after apply, and update symbolic links or junctions in ways that point to incorrect targets in some scenarios. For a full-system backup, Microsoft recommends Windows Backup, Windows Server Backup, or another tool designed for that purpose. Read Microsoft’s explanation of ImageX backup limitations.

The documented process is to prepare an operating-system installation with Sysprep, capture it from Windows PE, and apply the resulting image to another computer. The specific command syntax and deployment steps depend on the Windows, WinPE, and toolkit versions in use; the available Microsoft material does not establish a universal command sequence for unspecified environments.
#1 Best Overall
Before following an ImageX procedure, identify the target Windows release, WinPE version, processor architecture, and the version of WAIK or Windows ADK involved. Verify that the procedure applies to those exact versions rather than assuming historical instructions remain supported in a current deployment setup.
How to check an ImageX failure
Start by recording the failure rather than applying a fix associated with a different symptom. Note the ImageX command and exact returned error text, Windows and WinPE versions, processor architecture, and whether the failure occurs during capture, apply, or subsequent startup. The cited Microsoft sources do not provide a universal diagnostic command or a comprehensive error-code table.
Rank #2
Capture failure in Windows PE 3.0 on multiprocessor systems
Microsoft documents a specific intermittent capture failure under Windows PE 3.0 on multiprocessor computers running Windows 7 or Windows Server 2008 R2. One reported message is “The process cannot access the file because it is being used by another process.” Microsoft attributes this case to a timing condition in which two threads try to open a file at the same time. The scope is those documented legacy environments, not all ImageX capture errors. See Microsoft’s support article for the documented failure and resolution.

Its article also describes updating a mounted WinPE image: mount the image read-write with ImageX, copy an updated ImageX executable into the mounted image’s Tools directory, and commit the image. These are remedies tied to the stated Windows PE 3.0 scenario; do not apply them as a general fix for unrelated errors.
Post-deployment error 0x80070035 and credential prompt
A different Microsoft deployment troubleshooting reference covers a newly deployed computer that prompts for credentials and reports error 0x80070035, “The network path was not found.” In this specific scenario, check whether the WIM contains MININT or _SMSTaskSequence folders. These folders can be checked in the image; the reference does not identify them as a universal cause of ImageX failures. See Microsoft’s deployment troubleshooting guidance.
If the folders are present and cannot be removed through the ordinary mounted-image operation, the reference gives these commands to run from the root of the image:
RD MININT
RD _SMSTaskSequence
Use this check only when the deployed-computer symptom and WIM-folder context match the documented case. It is separate from the multiprocessor capture timing issue.

Check version support before using historical fixes
The cited guidance describes specific legacy platforms and symptoms; it does not establish whether ImageX is supported for an unspecified present-day deployment environment. Confirm the exact Windows, WinPE, and WAIK or Windows ADK versions against the applicable Microsoft documentation before adopting a historical procedure. Keep the failure’s phase and error text in view so a capture workaround is not confused with a post-deployment network-path check.
