Third-party programs are not updated. In case of MikTeX this is technically not possible. For the other programs there is no urgent need to - there is no security issue that was fixed, the new version only provide new functionality (not used by LyX). In case there is a security issue, I'll anounce this separately. When you want to check out the latest versions of all third-party programs, then the safest way is to uninstall LyX 1.5.2 and then install lyx 1.5.3 using the complete installer variant.
