Even though Windows XP Service Pack 3 has a long way to go before being released to the public, word is out that Microsoft has Service Pack 4 in the works. SP3, set to be released in mid-2007, will be a massive update for XP, and many people have said it may be the last for the OS because of Vista.
But rumor has it that because of the massive delays with Windows Vista, Microsoft may be forced to release one final hotfix pack to keep corporate IT customers happy due to the predicted delay in switching to Vista for many companies.
A Chinese version of PC Magazine spilled some small tidbits about SP4 last year that went unnoticed, stating that it's on Microsoft's release timeline. A quick search of the internet can find scattered referrals to the package as well.
We've heard that there will be no new features with SP4, but most likely there will be many fixes for both IE7 and WMP11 as the products mature. Although no known fixes have been designated to SP4 just yet, TheHotfix.net will be the first to bring them to you when they begin arriving, most likely early next year.
