A fix for the multifile-selection glitch in Windows 7 and 8
Found on CNet News on Monday, 15 April 2013

Sometimes you wish Microsoft would let customers decide when to delete a feature. Reader Dan Baechlin depends on Windows Explorer's ability to retain the selection of multiple files after changing the sort order. The feature has been removed from the version of Explorer in Windows 7 and 8.
Ramesh Srinivasan devised a Registry tweak that disables the Full Row Select option in Windows 7 and 8 Explorer windows, and that has the side-effect of preserving multifile selections when re-sorting from Name to Size, Date modified, or some other category.
Windows 7 and 8 are only glitches. The explorer happily displays the size for each file in a directory, but if you select more than 15 files, Microsoft decided that it would be a great improvement to not sum up those sizes anymore; instead you need to do an extra click to display that information. Not to mention that the total size and free space information too vanished from the status bar for whatever obscure improvement reasons.
