What Is "Windows XP Seven Royale SP3 2010"? This is not an official Microsoft release. It is a custom, unofficial "theme pack" or modified ISO created by enthusiasts to make Windows XP look like Windows 7 (often including the "Royale" theme, taskbar, icons, and wallpapers). The "SP3 2010" tag suggests it integrates Service Pack 3 with updates up to roughly 2010.
