Windows 7 Service Pack 1 (SP1)
Windows 7 Service Pack 1 2014

Windows 7 has been held up as one of the best editions of the OS to ever come out, but most people who use this edition of the Windows OS also realize that it's only able to reach its full potential with the addition of Windows 7 SP 1.

An Overview of Windows 7 SP 1

A few years ago, the Windows operating system was almost rendered obsolete. After releasing Vista, which was an OS full of bugs and oddly intrusive administrative control prompts, Windows was boycotted around the entire globe. Only a year or two later, however, Windows got back to their XP roots and released Windows 7, which still today is still considered one of the company's crowning achievements, even though we're already up to Windows 10. Win 7 is still considered the standard, and most people understand that a software package like Windows 7 SP 1 simply expands the functionality of the OS. SP 1, or Service Pack 1, is a complete suite of tools, add-ons and updates for the Windows 7 OS, and it includes a lot of great programs and features that will really help you fine-tune your PC.

This important update for the Windows OS helps to improve the stability of the OS, its security, and even its overall speed. There are a lot of different options within this pack that will help you increase your start-up speed, your browsing speed, and even help to tune up your Internet speed. While this used to pop up for Win 7 users automatically, you have to understand that we're up to Win 10 already, and so the Win 7 auto-updates don't include SP 1 anymore, and so you have to manually find this package.

What Windows 7 SP 1 Is and What It Does

To understand Windows 7 SP 1 at its roots, you simply have to look at it as a series of vital updates for your operating system. They're not the typical updates that will require you to restart your PC every other day, and have to restore your system every month because of something incompatible. Instead, these are updates that deal necessarily with the security of your system and its operating speed. So, simply put, every Win 7 user would do well to include this SP 1 update.

If you're running Windows 7 without the SP 1 updates, you're missing out on dynamic memory features, the RemoteFX update that helps with your system's VR capabilities, and a lot of graphics updates to your GPU, whether you're using an onboard processor or standalone card. The Win 7 SP 1 service pack is genuine Windows software that's free to download, relatively easy to install, and it will help to eliminate a lot of those useless updates you're prompted to reboot for every few days.
