titleImportant Update

Please note that Windows 10 18234 is now part of the live Windows 10 kernel. This is no-longer an Insider Preview issue.

Macrium Reflect has now been updated to resolve this error.

We have been made aware of a problem with the C: drive NTFS file system that affects all installations of the Windows 10 Insider Preview Build 18234.


Unlike other imaging products Macrium Reflect uses the file system meta data described above to determine the location and size of key file system structures. There are Windows APIs that also retrieve this data but Macrium Reflect reads values directly from the file system meta data. The Windows API calls appear to be unaffected by this problem. We believe that for the $BITMAP file the size is being calculated from information in the data stream attribute. Please note that this doesn't mean that other products have a better implementation, it simply means that they are unaffected by the problem. 

What's the solution?

It is very likely that this issue will be fixed by Microsoft before going live with this kernel. In the meantime, we have a hot-fix for Windows 10 Insider Preview customers that will ensure that Macrium Reflect is not affected by this attribute error.  

Note:  The fix in the below patches has now been released into Macrium Reflect v7.2 and it is no-longer necessary to apply them.  If you haven't done so already please upgrade to Macrium Reflect v7.2 or later.

If you are running v7.1.3317 then run the appropriate downloaded patch from any location on your PC to upgrade to v7.1.3570.

Run the appropriate downloaded patch from any location on your PC to upgrade from v7.1.3317 to v7.1.3570.

Note: If you aren't currently running v7.1.3317 then please take the 'Other Tasks' > 'Check for updates' menu option in Macrium Reflect and update prior to running the patch.
