With an estimated 25% of Windows users still preferring to run Windows XP, the unofficial SP4 package should be worth dedicating time for. The developer has termed the unofficial Windows XP update package as the 'Unofficial Service Pack 4 (SP4)' and the SP4 package is now available for download for Windows XP users across the world. Greece-based developer Harkaz claims to have integrated all official updates that Microsoft has issued to Windows XP users into a single package which is currently in its third beta state.

Windows XP, Microsoft's popular operating system, may have reached the 'end of life' stage in April this year, but this has not prevented a Windows XP enthusiast developer from releasing an ' unofficial Service Pack 4' for users still running the operating system.
