Windows 10 ISO file does not mount (Technical Preview for Enterprise)

The current “Windows 10 Technical Preview for Enterprise” can be downloaded from the Microsoft website. To be able to do that, you have to sign up for the “Windows 10 Insider Program”.

The current November Build can be downloaded after registration: Download Windows 10 Technical Preview for Enterprise.

However, problems with mounting the Windows 10 ISO can occur:
 

Windows 10 ISO – “File could not be provided…”

After downloading, you`ll have an ISO file of about 4GB:
9879.0.141103-1722.FBL_RELEASE_CLIENTENTERPRISE_VOL_X64FRE_en-us.ISO

Trying to mount the ISO file in a Hyper V-session or locally in Windows 8.1, the error message “File could not be provided, problems with providing the file” is displayed.

 The sources of the problem are the file attributes. Windows denies the mounting of ISO files where the so-called SPARSE attribute is set.
 

Show SPARSE attribute

With Powersehll you can display the set file attributes.

Reset SPARSE attribute

With the tool “FSUTIL” you can reset the SPARSE attribute:

fsutil sparse setflag “Dateiname” 0

Control SPARSE attribute

After resetting the attribute with “FSUTIL“, it is no longer displayed in the Powershell:

Mount ISO file in Hyper-V

After getting rid of the SPARSE attribute, the ISO file can be embedded into Hyper-V without problems.

 After the successful installation, the testing of the Windows 10 Technical Preview for Enterprise can begin, e.g. with the new Windows 10 start menu:
