php Regex file path | second matching after specific character

I trying to extract file patches, without disk letter, that are inside text. Like from AvastSecureBrowserElevationService; C:\Program Files (x86)\AVAST Software\Browser\Application\elevation_service.exe [X] extract :\Program Files (x86)\AVAST Software\Browser\Application\elevation_service.exe.

My actual regex look like this, but it will stop on any space, which can contains file names.

(?<=:\\)([^ ]*)

The soulution that I figure out is, that I can match first space character after dot, because there is very little chance that there will be some directory name with space after dot, and I will always do fast manual check. But I do not know how to write this in regex

You can use the following regex:

[A-Z]\K:.+\.\w+

It will match any capital letter followed by :, then any character string ending wit ., followed by at least one word character.

\K removes from the match what comes before it.

Here we would consume our entire string, as we collect what we wish to output, and we would preg_replace:

.+C(:\\.+\..+?)\s.+

Test

$re = '/.+C(:\\.+\..+?)\s.+/m';
$str = 'AvastSecureBrowserElevationService; C:\\Program Files (x86)\\AVAST Software\\Browser\\Application\\elevation_service.exe [X]';
$subst = '$1';

$result = preg_replace($re, $subst, $str);

echo $result;
