- Registry validator: increased tolerance to the leaks of allocated cells in the registry hives. They started to appear since Windows 10.1804 and seem to be caused by recent changes in MS Windows registry implementation code. Emergency Boot Kit must be able to open and update such registry hives regardless.

- Added support for viewing and editing access/layered bits for registry keysThese features were originally introduced in Windows 10 Redstone 1.

New in Emergency Boot Kit 1.5i (Feb 26, 2018)
- Starting from this version, Mount & Boot Center takes into account offset on disk for boot partition when verifying boot path from BIOS. If offset on disk for boot partition is wrong (usually after transfer from another disk), then Windows does not emit any error messages, just endlessly blinking cursor on black screen.
New in Emergency Boot Kit 1.5h (Feb 20, 2018)
- Before this version, Mount & Boot Center could not detect Windows Loader in EFI System Partition, if said EFI System Partition was just created in the Partition Manager (a reboot was required). Reboot is no longer required.

- The following assertion failures in the Mount and Boot Center have been fixed: 1626/BK5SC (in 64-bit build) and 2859/YE5WU (in 32-bit build). They weren't independent errors, and always were fired side-by-side with other errors (e.g. unreadable disk or corrupt registry hive).
- Both bootloaders (UEFI and BIOS/CSM) are now caching File Allocation Table in chunks of 128 Kb, instead of loading the whole table. This should improve compatibility when booting from large USB HDDs.
- Validation rules for symlinks in the Windows Registry have been relaxed. Apparently there are third party software which creates other values besides REG_LINK in registry keys with symlink flag.
