Hi Microsoft Team!
You should make a new operating system called: "Windows 98 Third Edition".
Windows 98 looked good and was easy to use, but since there are no updates for it anymore, it doesn't really work anymore. Windows 98 Third Edition (TE) would look and act the same as Windows 98 Second Edition (SE), but it would get security updates, bug fixes, compatibility updates so that new computers and screens work with it and new software works on it.
It could also have some new features, themes, backgrounds and so on. One of the features could be search bar in start menu, and aero theme could be one of the new themes.
