Updates KB3179573 and KB3179574 for Windows 7, 8.1 improve system stability

If you’re running Windows 7 or Windows 8.1, you can now download the August service pack and install the latest system improvements and bug fixes. These updates are optional, and if you turned on the Windows Update center, you still need to install them manually, and they won’t download automatically.

If you’ve never paid attention to these monthly service packs, you should start to download them regularly as they combine previously released updates, making Windows more reliable. Keeping your Windows 7, or Windows 8.1 OS up to date prevents bugs and various issues as well. Usually, service packs take about 30 minutes to install, and at a given moment, the installation process will also prompt your to restart your computer.
