A Defender?
I am going to assume you mean, Windows Defender. Its is a program that helps (doesn't do a great job) prevent malicious software from ruining your computer.

There is no version of DirectX 10 for Windows XP.
Microsoft does not provide free trials of Windows XP.
You can't have Windows Movie Maker version 2.6 on Xp operating systems. Windows Xp can only load the 2.1 version of the program. Sorry.
No, there isn't.
Nowhere.
Windows Movie Maker 2.6 is a Vista ONLY download. Unfortunately, Xp users can only download the 2.1 version of Windows Movie Maker.
Windows XP
You can't downgrade Windows Live Movie Maker. However, you can download v2.1 (Xp) or v2.6 (for Vista) since each is a stand-alone application. I have posted links to the downloads in the Related Links section below.Note: You cannot download the Xp version of Windows Movie Maker on an operating system other than Windows Xp. The download will not work. Choose the download compatible with your operating system. Also, if you have Windows 7, you can only download version 2.6 (Vista).
One can download a free trial version of WinZip 10 from the cnet website; the full standard version may be purchased for $29.95. WinZip 10 is suitable for Windows98/Me/2000/XP; the newest version is WinZip 17 and is suitable for Windows XP/Vista/7/8.
You can, however the latest version is only for windows Vista and 7. To download it to XP or earlier, look for a small link on the download page that leads to earlier versions of iTunes (I know 9 works for XP).
You can download the free Bit Defender software at the official Bit Defender website. You can also download it through the software hosting website CNET.
I believe that Neooffice is simply a version of openoffice, which is for PC, that is made for macs.
