Macrium Reflect X v10.0.8731
Date 19th November 2025

Bug fixes and Improvements, v10.0.8731 - 19th November 2025

  • Image Mounting
    • The option to mount images writable has been reintroduced for Reflect X. Please note that this functionality mirrors that in previous versions of Reflect and all changes will be lost when the image is dismounted.
    • In some cases, dismounting an image could fail to remove the drive letter from Windows Explorer. This issue has been resolved.
  • Rescue Media
    • We have added new "Boot Media Signing Certificate" options to Rescue Media Builder when building 64-bit PE11. The successful use of these options requires clearing the Rescue Media cache first. To do this, start the Macrium Reflect Uninstall program via Windows Control Panel, then deselect the first 3 checkboxes, then select the "Remove Windows PE Component Files" checkbox and click OK.
    • The "On Completion" option set to Do Nothing was not always honoured in the Windows PE Rescue Environment. This issue has been resolved.
    • For users who have enabled the Reflect password feature, the Taskbar application in Rescue Media no longer allows unauthorised browsing of the file system.
    • On ARM systems, the Taskbar could fail to load with an out-of-memory error. This issue has been resolved and the Taskbar has been given a more modern look-and-feel.
  • Performance Improvements
    • Reflect now uses OpenSSL for encryption and decryption to further improve security and performance. These changes work seamlessly across existing and new image files and do not affect compatibility between Reflect versions.
    • Image file loading times have been reduced, leading to improved UI responsiveness.
    • Imaging performance to Thunderbolt/USB4-attached NVMe storage devices in the Windows PE/Rescue Environment has been improved.
      To enable this feature, set: HKEY_LOCAL_MACHINE\SOFTWARE\Macrium\Reflect\Settings DWORD NoDiskThrottle = 1
    • Imaging performance over SMB Multichannel-capable networks has been enhanced to better utilize available bandwidth and reduce backup times.
      To enable this feature, set: HKEY_LOCAL_MACHINE\SOFTWARE\Macrium\Reflect\Settings DWORD SMBMultiChannelSupport = 1
  • Other Fixes and Improvements
    • Fixed an issue where Network Root alternatives in the XML definition file were not properly populated, which could result in a Full backup being created instead of an Incremental or Differential backup.
    • In some environments, Scheduled Tasks were running under the SYSTEM account even when configured to run under a USER account. This has been resolved.
    • Addressed an issue where File & Folder Restore and Search filter operations could fail when the Reflect language was changed between the Backup and Restore operations.
    • In rare cases, creating Incremental or Differential images when the Full image was created without a password, and the XML definition file was later updated to include one, could result in incorrect Incremental/Differential files. This issue has been resolved.
    • Fixed an issue where the CPU priority setting might not be applied correctly when adjusting the slider at the very beginning of a backup, particularly during File & Folder backups.
    • viBoot could fail to detect the active partition in images containing certain MBR disks, resulting in an error. This issue has been resolved.

Bug fixes and Improvements, v10.0.8665 - 25th September 2025

  • Imaging
    • Changes to the order of physical storage devices across a backup-set could result in Reflect erroneously reporting that the backup-set is corrupt. This has been resolved.

    • Addressed a problem that could result in excessive memory usage and/or errors being reported during the Incremental backup process. This issue only arises when using a custom file name and/or path containing non-ANSI (non-English) characters.
      Note: New backup sets will not be affected by this issue. If you require access to an affected backup set and are experiencing issues, please contact support.
    • Fixed a problem where the system could fail to boot with a "boot disk not found" error after restoring images to different disks using Drag and Drop or when using the Shrink or Extend to fill target disk options.

    • The disk icon associated with mounted images could persist after the drive was dismounted. This has been resolved.

Bug fixes and Improvements, v10.0.8447 - 12th February 2025

  • Imaging
    • We have discovered a timing issue that affects the display order of existing backups and in some cases prevents the user from interacting with parts of the Reflect UI. This has now been resolved.

Bug fixes and Improvements, v10.0.8445 - 10th February 2025

  • Imaging
    • Reflect would sometimes display the Macrium Image Guardian (MIG) icon in the backup progress window. This has now been rectified.
    • Previously, Reflect backup notifications were sometimes incorrectly labelled as "Restore." This issue has now been fixed.

Bug fixes and Improvements, v10.0.8406 - 2nd December 2024

  • Updating To This Release
    • This update requires a full installation; patch files are not available.
    • Important: After installing this build, please rebuild your rescue media to ensure that it includes the latest fixes.
  • Imaging
    • Legacy incremental backups of FAT32 partitions could fail during verification due to a decompression issue. This has now been resolved.
    • Exclude Files From Image Backups was not excluding the Downloads folder if the default location had been changed. This has now been rectified.
  • Consolidation
    • The standalone consolidation tool consolidate.exe could fail to open some .MRIMGX files. This is now fixed.
  • viBoot
    • viBoot backups used an incorrect path for full backups, while differential and incremental backups worked correctly. This issue has now been resolved.
  • General
    • The feature to delete old backup sets when the free space threshold is reached and the resumable images option is set has been re-enabled. It was disabled in the previous release.
    • When attempting to browse the contents of an ReFS formatted volume, the virtual drive could fail to mount. This has now been resolved.

Bug fixes and Improvements, v10.0.8366 - 4th November 2024

  • Imaging
    • We've resolved an issue with GPT to MBR restores. When restoring a GPT partition into free space after an existing MBR partition using drag and drop, the restored partition could become hidden in Windows.
    • Previously, image backups would fail if there wasn’t enough space in the destination folder, without prompting to select a new folder. This issue has now been resolved.
    • When using manual file names without a unique prefix selected, the numeric collision sequence number added to the end of the file name to prevent overwriting existing files, may not have remained consistent across all files in the set. This issue has now been resolved.
      Note: This situation is very rare, and the fix will only apply to new backup sets. Existing sets will continue with an additional collision number.
  • viBoot
    • A viBoot virtual machine that was created from a Reflect X incremental or differential image could sometimes fail to boot. This has been resolved.
  • Scheduled Backups
    • Resolved an issue where scheduled backup tasks could unintentionally run twice when set to execute at Windows logon.

Bug fixes and Improvements, v10.0.8324 - 17th October 2024

  • Imaging
    • We've resolved an issue where an incorrect "File and Folder" error message prevented mounting image files containing partitions larger than 2TB.
    • We've fixed a bug that could cause the restore process to fail with the incorrect error message: "A component's file does not match the verification information present in the component manifest."
      Important: After updating to this build, please rebuild your rescue media to ensure the restore process includes the latest fixes.
  • viBoot
    • We’re highlighting VirtualBox 7.1 support in viBoot, added in our last release to enhance virtualization compatibility.
  • General
    • Fixed an issue where the license key might not be visible in the About box.
