Why ask that ? Why you scare to just update ur software to the latest version ?
In the description its write fix various bug.
Are you on windows xp or vista ? lol, i dont understand the point of asking this.
Update it and if you feel verry sad after just unistall it and ré-install the version you want.
Even you ask anything to others, nothing worth ur experience on ur machine, this is how its working dude.
