Question about Microsoft Windows XP Professional With Servise Pack 2 (e8503040) for PC
The problem is with one of your installed programs that has a bad custom uninstall icon registrations - likely the last one listed before the gap, though it could be the one listed after the gap. And in one case, the program that was causing the gap was not otherwise displayed at all in the add/remove programs list!
If you go to the registry key HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall, you'll find a list of programs that have registered for appearing in the Add or Remove Programs control panel. Some of them might have been so kind as to provide a "DisplayIcon" value, thereby saving the control panel the indignity of having to guess at an appropriate icon.
Unfortunately, if they put a bad icon registration in that registry value, the result is a bunch of blank space since the control panel is trying to reserve space for a bogus icon.
The format of the icon registration is a filename, optionally followed by a comma and a decimal number.
Since this is not a command line, quotation marks are not necessary (although they are tolerated). Furthermore, the number can be any value except for -1. Why is -1 forbidden? Because the ExtractIcon function treats the value -1 specially.
If the icon file does not exist in the icon file, or if the icon number is -1, then the icon specification is invalid and the Add or Remove Programs control panel will reserve an odd amount of space for an icon that doesn't exist.

Reinstalling Windows can be done in two ways...
1. Install it over your current installation.
2. Install from scratch.
The best thing to do is back-up data on some other disk that you cannot miss. Make s since a clean install will erase all data. Installing Windows over your existing installtion is not advised since it makes a huge mess out of things.
I'm not sure about the upgrade CD. It should work, if it doesn't you need to install a copy of XP first and then use the upgrade CD over it.
I hope this helps you out. Please rate the solution.
