For all those Macrium Reflect users the latest Version. 5.2.6354 was released 2nd August 2013 - available for download now are versions Free, Standard, Pro and Server (32bit and 64bit) OS XP through to Windows 8.0 Inclusive.
I'm still on 4.2 myself with WinXP and don't particularly care for the newer Macrium versions, although if I were on something like Win8/8.1 I'd upgrade it and then just put up with a newer freeware version.
Thanks Alan_B and you're right there are many differences between 4.2 and 5.2 which I now understand, have installed, tested and verified the backup image after booting with the Windows PE boot disc.
I also did perform a backup prior to the installation (as is my normal practice prior to installing any major software apps) and I'm pleased to say all seems OK other than testing a "restore" which I will do within the next 7 days.
Macrium Reflect has never let me down in the past, saved me many times and I feel sure/safe using the new version
