Troubleshooting Windows 8 Update Error 80246003
“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.

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.
Open the Notepad, copy and paste all of the following commands in it, and save it as Windows8Update.BAT
regsvr32 c:\windows\system32\vbscript.dll /s regsvr32 c:\windows\system32\mshtml.dll /s regsvr32 c:\windows\system32\msjava.dll /s regsvr32 c:\windows\system32\jscript.dll /s regsvr32 c:\windows\system32\msxml.dll /s regsvr32 c:\windows\system32\actxprxy.dll /s regsvr32 c:\windows\system32\shdocvw.dll /s regsvr32 wuapi.dll /s regsvr32 wuaueng1.dll /s regsvr32 wuaueng.dll /s regsvr32 wucltui.dll /s regsvr32 wups2.dll /s regsvr32 wups.dll /s regsvr32 wuweb.dll /s regsvr32 Softpub.dll /s regsvr32 Mssip32.dll /s regsvr32 Initpki.dll /s regsvr32 softpub.dll /s regsvr32 wintrust.dll /s regsvr32 initpki.dll /s regsvr32 dssenh.dll /s regsvr32 rsaenh.dll /s regsvr32 gpkcsp.dll /s regsvr32 sccbase.dll /s regsvr32 slbcsp.dll /s regsvr32 cryptdlg.dll /s regsvr32 Urlmon.dll /s regsvr32 Shdocvw.dll /s regsvr32 Msjava.dll /s regsvr32 Actxprxy.dll /s regsvr32 Oleaut32.dll /s regsvr32 Mshtml.dll /s regsvr32 msxml.dll /s regsvr32 msxml2.dll /s regsvr32 msxml3.dll /s regsvr32 Browseui.dll /s regsvr32 shell32.dll /s regsvr32 wuapi.dll /s regsvr32 wuaueng.dll /s regsvr32 wuaueng1.dll /s regsvr32 wucltui.dll /s regsvr32 wups.dll /s regsvr32 wuweb.dll /s regsvr32 jscript.dll /s regsvr32 atl.dll /s regsvr32 Mssip32.dll /s
Make sure that Save as type: is set to All files (*.*)
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.
