Each of the expressions for Conditional Comments give either “true” or “false” (for the latter, to be more precisely, their negations give “true”):
As you can see, all expressions work correctly. The test checks for variations on version numbers, most of which are supposed to be acceptable syntax according to Microsoft.
Problems occur in IE 5.5 (only “IE 5.5000” works) and old versions of IE 5.0 (in IE 5.01 only “IE 5.0100” works, so if you want to target all IE 5.0 versions you need to check for “IE 5.0 or IE 5.0100”), so this table may give you some reasoning why to avoid those problematic version numbers in your CC’s.
Note: Support for Conditional Comments is removed in IE 10.
This means you can only use Conditional Comments in IE 10 when using Compatibility View, which makes IE 10 emulate legacy IE versions.
So if you want to target Internet Explorer 5.0-9.0 (and not IE 10 and higher, because of the removal of Conditional Comments support) you can just use “if IE”.
