Microsoft has announced that Windows 7 SP1 will begin rolling out to consumers via Windows Update starting tomorrow. Windows 7 SP1 is over two years old and if you haven’t upgraded by now, Microsoft will do you a favor and apply it to your machine for you.
Not all PCs running Windows 7 RTM (RTM will no longer be supported after April 9th, 2013) will receive the update as those machines that are managed by a Microsoft management tool such as Systems Center Configuration Manager (SCCM) or WSUS Server will be able to void SP1 if necessary.
Seeing that SP1 includes many security enhancements and general bug fixes for the OS, it’s hard to find a reason why the average consumer would not want the update on their machine.
The rollout, like all other large updates from Microsoft, will be released gradually over the coming weeks and you should be prepared for the update to take a bit of time to install.
If you do not currently have SP1 installed, be on the lookout in the near future as Microsoft is about to install it on your machine to make sure you have the latest goods to keep your computer running smoothly.
