Duplicating my results: Having made an Image Backup of Windows 7 Professional with Service Pack 1 immediately after completing the “Clean Install” (without any updates installed); I restored this image to take a second attempt to verify the steps listed above were repeatable.
I installed the “Speed Up Windows Update” updates mentioned in Step #1, then installed the “Rollup updates” in step #2 and verified they installed without any issues.
Although it is generally recommended that you install updates in small batches, this time I got bold and decided to install all the updates at once. I expected some of the update to fail to install but usually a second try will installed the failed updates.
All 30 updates; time to download = 5 minutes. Time to install = 8 minutes for first prompt to “Restart”, Restart and “Stage 3 of 3 / Configuring Windows update” 2:30 seconds. All updates (including IE11 and .Net Framework updates) installed successfully.
Reran Windows Update; time to complete checking for updates = 21 minutes. (As previously mentioned, this is due to the installation of IE11 which after being installed in the previous step comes with its own set of updates.) 9 “Important” updates listed. Total time to Check for updates, download and install the 9 updates, restart required and complete the installation of these 9 updates = 28 minutes and 30 seconds.
Total time to install the prerequisite / rollup updates and all “Important” updates (as of May 22nd, 2016), 1 hour and 32 minutes. This is about an hour faster than download Windows Update in small batches but is more risky. My Image Backup was my safety net in case some of the updates failed to install even after retrying to install a failed or failed updates a second time. The risk is yours but I would choose the 1st method as the extra hour it took was still far less time than the painful almost all day effort it took without the speed up and rollup update package.
Reran Windows update one more time, time to complete checking = 2 minutes. The only updates listed were the “Optional” updates.
Note: You may see one important update listed but not selected (checked), this is KB971033 (Windows Activation Technology) update which I never install. Right click and hide it.
