It bundles together a large number of updates that would take a very long time to install normally.
This package includes updates released from February 2011 all the way to May 16, 2016.
To speed up the updating of a new Windows 7 system, download the convenience rollup and install it rather than waiting for Windows Update.
Unfortunately, Microsoft doesn’t offer the update rollup through Windows Update–you have to go out of your way to get it.
You’ll be asked to restart the computer as part of the installation process.
After it restarts, Microsoft says you should wait ten to twelve minutes to allow the process to finish.
Here are Microsoft’s official instructions for fixing the problem. After the computer restarts, you’ll need to manually download and install two updates for Windows 7.
You’ll need to check whether you’re running a 32-bit version of Windows or a 64-bit version and download the appropriate updates for your PC.
When you’ve booted into Safe Mode, the next step is to stop the Windows Update service, and the easiest way to do that is with the Command Prompt. This occurs even if you install Windows 7 from a disc or USB drive with Service Pack 1 integrated, which you should.
It’s a third-party tool called WSUS Offline Update.
This tool will download available Windows Update packages from Microsoft and install them.
For 64-bit editions of Windows 7, download these updates: Double-click the “KB3020369” update to install it first.
After the first update finishes installing, double-click the “KB3172605” update to install it second.
