The first service pack for Windows 7 has been released this month and after waiting to hear about any catastrophes I installed it last night on my two Windows 7 machines. The install went without a hitch and I have not noticed or seen any OS enhancements. There was some talk about HD audio – but um yeah what’s that? So apparently this is a roll up and enhancement for Windows 7 security so go get it and be prepared to be offline for anywhere from 10 minutes to 30 minutes depending on the size of your system. Keep your computer up to date and be secure. And be like me and wait a few weeks after a Service Pack release to gauge the issues stemming from installing it! You can read all about the bugs this fixes here. Good luck.
The download can be grabbed via Windows Update or via this link for a manual installation.
