Dec, 03 of 2018 Minor update 1.5q released.

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.

Dec, 02 of 2018 Minor update 1.5p released.

Starting from this version, validation rules for Windows registry were relaxed to allow embedded NUL characters in the registry key names and in the registry value names. Apparently there is some third party software relying on these features.

• Added support for viewing and editing new registry hive: SYSCACHE.HVE in "System Volume Information" folder.
• Added support for viewing and editing access/layered bits for registry keys. These features were originally introduced in Windows 10 Redstone 1.

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.

Feb, 19 of 2018 Minor update 1.5h released.

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.

Fixed incompatibility of Registry Defragmenter with Windows 10 Fall Creators Update

Jul, 12 of 2017 Minor update 1.5f released.

• 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.
• Block devices with unreadable first sector and zero-length block devices no longer prevent Mount and Boot Center from starting.
• Readonly filesystems on fixed disks now yield clearer diagnostics in demo version.
