Troubleshooting Windows 8 Update Error 80246003

Reader Question:
“Hi Wally, I am trying to update Windows 8 using Windows Update but I keep getting “Update validation failed, error 80246003″. I’m using Windows 8 Enterprise edition on my computer.” – Gregory R., USA

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 Windows 8 update error is basically the same error that used to occur with Windows update in the past. There are some really simple fixes that should solve your problem.

Windows 8 update is not installing any updates. It stops every time and gives the Error 80246003.

Cause

  • Corrupt Windows 8 files.
  • Corrupt registry files.

Solution

There are some things that we can do to fix this Windows 8 update issue. These range from general troubleshooting to more specific fixes. Although general troubleshooting fixes many problems with the Windows updater.

General Windows update Troubleshooting

Stopping Windows 8 Update Services

  1. Open the Command Prompt as Administrator by pressing the Windows Key and typing cmd to search for it. (If you are using a touch display than swipe the screen from the right side and select the Search icon, type cmd and long-press it to show more options, select Run as Administrator.)
  2. Right-click the cmd icon and click Run as Administrator.

Registering DLL files related to Windows 8 update

Because there are many DLL files, its better to make a .BAT file for running all these commands.

Executing this BAT file will execute all of these commands so you don’t have to type them in one by one.

Starting Windows Update Services

On the command prompt (Run as Administrator), type the following commands and press Enter after each command just like last time.

net start wuauserv
net start bits
net start cryptsvc
exit

Now, check for updates using Windows Updates again.

Scan the Computer’s Registry

Registry errors can harm Windows system files and cause software to malfunction. Use a reliable registry scanner to automatically and regularly scan your computer for errors.
