Some people always ask: why does my Windows 7 update to sp2? I thought it must be a joke when I saw this question at the first time, but more and more people find the words — Service Pack 2 in the System Properties. So did Microsoft have released the SP2 for Windows 7 in secret?
As we known, Microsoft hasn’t released the final version of Service Pack 1 for Windows 7, how the SP2 appeared frequently? Actually the version of SP which displays in System Properties is controlled by a key from system registry. The real Service Pack, some computer games’ patch or even some malware will change this key when they are installing. It’s just a key was changed but will result some software can’t be installed. So if your Windows 7 was updated to SP2 unaccountably, you’d better to change it back by yourself because you can do it easily!
