KB4497934 Will Not Install: How to Fix It?

Microsoft recently released Windows 10 cumulative update KB4497934 (OS Build 17763.529). The new update brings along notable modifications that will improve your overall experience with Windows 10. Earlier this year, the company promised to boost the upgrade functionality that lets administrators decide when to install new feature updates. Thankfully, the cumulative update KB4497934 finally address this functionality.

Generally, the update includes several quality improvements, but it has no new OS features. Here is an overview of changes that came with the update KB4497934:

  • Fixed an error that triggers Internet Explorer to stop responding to requests as well as a looping redirects issue between Microsoft Edge and Internet Explorer.
  • Resolved an issue that may trigger Microsoft Edge to hide annotations that you add to PDF files, such as highlights, comments, and inked notes.
  • Resolved an error that causes useful applications like Microsoft Office to ask for a password following a change in user account password.
  • Addressed an issue that limits users from logging in to a Microsoft Surface Hub gadget using an Azure Active Directory account.
  • Addressed an issue that inhibits Num Lock from working effectively in a Remote Assistance session. This problem mostly occurs when a Remote Assistance window gains and loses focus.

It is apparent that the update KB4497934 comes with several good things. But just like most cumulative updates, not everything is perfect with the update. As Microsoft stated, you may encounter an error when printing from Universal Windows Platform (UWP). You may also experience challenges while using the Preboot Execution Environment (PXE), especially when starting your device from a Windows Deployment Service (WDS) server.

Besides these known bugs, it appears that the new update is troubling users. Some users reported encountering setbacks while trying to install the cumulative update KB4497934.

Why KB4497934 will not install?

There could be more than one reason why KB4497934 will not install. If your Windows 10 update KB4497934 stuck during download, probably at 0% or 99%, there is a high chance that something went wrong with the file itself. Maybe your Internet connection got interrupted while downloading the update files, or the update database got damaged, or your security software blocked update files from installing on your system. But the most likely cause of this issue is corrupted Windows update cache.

How to Fix KB4497934 Not Installing?

If you encounter challenges while installing the KB4497934 update, please follow these troubleshooting steps.

Step 1: Disable Antivirus Software and Perform a Clean Boot

Sometimes, your antivirus program may prevent you from installing updates. So, disabling it before installing the available updates may help to resolve the issues. Clean booting your PC is also necessary. Please follow these steps to clean boot your Windows:

  • Enter msconfig in the search box and execute it.
  • Now select System Configuration and navigate to the Service tab.
  • After that, select Hide all Microsoft services > Disable all.
  • You will also need to stop unnecessary running services. To do this, go to the Startup tab and select Open Task Manager. From here, disable all unneeded services running there.
  • After that, restart your PC and check for updates.

Step 2: Run SFC and DISM

If you suspect that your Windows system files are missing or corrupted, we suggest that you run the SFC utility and the DISM restore health command before checking for the latest updates. Here is how to do it:

  • Enter cmd in the search field and tap Enter.
  • Now right-click on the Command Prompt option and choose Run as administrator.
  • Wait for the Command Prompt window to open, then type this command: DISM /Online /Cleanup-Image /RestoreHealth.
  • When the scanning process finishes, run this command: sfc/scannow. The SFC utility will detect and restore problematic files.
  • Wait from the process to complete, then restart your computer and check if KB4497934 fails to install again.

Step 3: Run Windows Update Troubleshooter

The Microsoft team, fully aware of Windows update failure, designed the Windows Update Troubleshooter to help you detect and fix errors that prevent you from installing updates. Here is how to run this built-in tool:

  • Press the Windows + I keyboard combo to open Settings.
  • Select Update & Security > Troubleshoot.
  • Look for Windows update in the middle of the pane and click on it.
  • Now click on Run the Troubleshooter to scan for and fix any error that may prevent Windows Update from downloading and installing updates.
  • Wait for the troubleshooting process to complete, then restart your PC to get a fresh start.

Step 4: Clear Buggy Windows Update Files

If KB4497934 fails to install even after running SFC and DISM, you can follow the steps below to clear buggy Windows update files:

  • First, you need to stop the Windows update services from running. To do so, launch the Command Prompt window as administrator and execute this command: net stop wuauserv. Now type ‘net stop bits’ in the Command Prompt window and press Enter. This command will halt background intelligent transfer services.
  • After that, go to this location: C:\Windows\SoftwareDistribution\Download.
  • Delete all the files in this folder, but don’t delete the folder itself.
  • When you are through with deleting problematic update files, you may need to run net start wuauserv and net start bits to reactivate the services you previously stopped.

A less risky way to clear buggy update files is to use a reliable repair tool, such as Outbyte PC Repair. This intuitive tool will not only scan your PC for errors, but it will also remove junk on your computer and restore missing or corrupt system files.
