This is a simple fix I discovered while working on a larger, more complex problem, when my entire computer was stuck “checking for updates.” Below only applies to fixing the issue with stand alone installers. If you need to fix the entire Windows Update / Microsoft Update feature of your computer, see my other article here.
- If the installer is currently stuck open on your screen, you can open task manager and kill it by ending the task WUSA.exe.
- Hold down the Windows Key and Press “R” on your keyboard to open the “Run” dialogue box. Type in services.msc and press the enter key or click OK.
- Scroll toward the bottom of the list and find the Windows Update service. Right click on it, and click Stop.
- Go to the folder where you downloaded standalone installer and double click it to run it.
- You may notice, at this point, that the Windows Update service starts back up. People may use Task Manager to note that SVCHost suddenly starts using over a gigabyte worth of memory, or other strange behaviors. However, in the few seconds before it starts to behave rampantly, your stand-alone installer should have taken off and started to install your update. The “checking this computer for updates” screen should disappear in under 10 seconds and the installation should begin.
