1. Start Windows 7, and log on to an administrator account.
2. Disable any 3rd party firewall, antivirus, or other security program to avoid it from possibly preventing the repair in-place upgrade installation of Windows 7.
3. Do either
step 4, step 5, or step 6 below depending if your
retail Windows 7 installation ISO/DVD/USB has SP1 or not, and if your currently installed Windows 7 has SP1 installed or not.
4. Repair Installed Windows 7 SP1 using Windows 7 with SP1 ISO
Note
If you do not have a Windows 7 with SP1 ISO, then you can download an official ISO with your retail product key from Microsoft at the link below.
Microsoft Software Recovery
You can also download the latest official Windows 7 SP1 Media Refresh (SP1 U)
ISO file at the link below, but this link is not always available for download.

A) If you have not already, you will need to install a program like
7-Zip that supports extracting a ISO to a folder.
B) Using the program (ex: 7-Zip) from step 1, extract the Windows 7 SP1
ISO file to a folder on a partition or HDD other than the current Windows 7 partition. (see screenshot below)
NOTE: For example with 7-Zip, right click on ISO, click on 7-Zip, Extract files, browse button, select where you want to extract to, and click on OK twice.

ISO file here:
Microsoft: Windows 7 Direct Download Links, and use
Windows 7 USB-DVD Download Tool to create a bootable DVD or USB flash drive with the ISO to do the repair install from within Windows 7 using this step.
It is preferred to have SP1 installed on your PC and to use

Windows 7 installation USB thumb drive, and click on the
