KB2770917 cannot be installed

Reader Question:
“Hi Wally, I’m using Windows 8 on Lenovo Yoga. Whenever I try to install a Windows update I get this error saying ‘KB2770917 cannot be installed’. The other updates install though..”   - Matthew C., Australia

Before addressing any computer issue, I always recommend scanning and repairing any underlying problems affecting your PC health and performance:

  • Step 1 : Download PC Repair & Optimizer Tool (WinThruster for Win 10, 8, 7, Vista, XP and 2000 – Microsoft Gold Certified).
  • Step 2 : Click “Start Scan” to find Windows registry issues that could be causing PC problems.
  • Step 3 : Click “Repair All” to fix all issues.

Setting up weekly (or daily) automatic scans will help prevent system problems and keep your PC running fast and trouble-free.

Wally’s Answer: This problem has primarily been keeping Lenovo yoga users from installing the KB2770917 update on their Windows 8 machines. This update installs on other computers without any problems whatsoever. It seems some third party software causes the problem. Software vendors are still catching-up to Windows 8, problems like these usually occur when a new version of Windows comes out. Lets look at some solutions to this problem.


Windows update ‘KB2770917 cannot be installed’ on Windows 8 Lenovo Yoga.


Third party applications are having conflict with the update.


Here is something you can try to get rid of this error:

  1. Open the task manager by pressing the Windows Key and typing task manager, then pressing Enter. (If you are using a touch display than swipe the screen from the right side and select the Search icon, type task manager and select it from the search results.)

  2. Close all the third-party software running on your computer by clicking the process and clicking the End Task button. This includes all non-Microsoft software like messengers, email clients, video software, browsers, etc. One of the pre-installed third-party software is probably causing problems with the update.

Try installing the upgrade again. This time wait for it to finish. It might get stuck but wait until its done.

  1. Open Windows Update by pressing the Windows Key and typing windows update, then pressing Enter.

Make sure the computer is plugged-in and the battery is charged, and don’t turn it off while the update is being installed.

Is Your PC Healthy?

I always recommend to my readers to regularly use a trusted registry cleaner and optimizer such as WinThruster or CCleaner. Many problems that you encounter can be attributed to a corrupt and bloated registry.

Happy Computing! :)
