    When I try it prompts me with the following; “The module “C\WINDOWS\SYSTEM32\WUAUENG.DLL” was loaded but the entry-point DllRegisterServer was not found.
    Make Sure that “C\WINDOWS\SYSTEM32\WUAUENG.DLL” is a valid DLL or OCX and then try again”.

    then type regsvr32 WUAUENG.DLL

  16. Lianne Menas says:

    Would you recommend disconnecting your Internet connection while running an antivirus scan? The reason I ask is temp files are continuously being written to while browsing the Internet. Is it not feasible that something gets missed during the scan if you can’t disconnect your connection?

  17. Sam says:

    I tried this solution, but it says the call to DllRegisterServer failed with error code 0x80070005

    What do I do?

    TY so much. I’ve been trying to get updates plus a prob with searches for 3 days. I even paid MS to get this fixed. I don’t know why I didn’t check the error number but it escaped me until today. I did a copy and paste and everything cleared up. TYTYTYTYTYTY

  55. Stu Mills says:

    Worked like a charm !!!!!

  56. Doug says:

    I used this tool for the SECOND time in 5 months due to XP Antivirus 2012 malware. I now have this saved into my Favorites menu so it will be easy to find next time…. as well as rkill and Malwarebytes on a flash drive so it takes less than 5 minutes to clear everything up. Thank you Google for allowing viruses to run rampant while doing a simple search for a stupid phone number! 🙂

  57. PPdiy says:

  69. FrankL says:

  70. Nathan says:

    Thanks it worked!!!

  71. dahveed says:

    This solution worked great… my system had been infected by a very persistent trojan, ‘Win32/Sirefef’ that turned off my Windows Firewall, Automatic Updates and corrupted my rundll32.exe file so that almost none of my applications or control panel features worked.
    After a thorough cleaning in Safe Mode using my antivirus software, the last little thing that was causing me a problem was not being able to install any Windows updates.
    Thank you again for your quick, easy registry fix…!

  72. cantstopfishing says:

    Thanks very much. I have never seen techiecorner before. You have helped me fix what no one else could. Cheers!

  76. Sky Walker says:

    Thanks! Worked great! Microsoft website and paid support was unable to help though. 😉

  77. Sky Walker says:

    P.S. I was at Microsoft site and also called Microsoft support (paid them $60) and they were unable to help! What losers those bill gates microsoft are… Thank you Techiecorner!

  78. Sky Walker says:

    It worked! Thanks very much!

  79. Andrew says:


  80. Troy says:

    Outstanding! worked perfect

  81. Doug says:

    Wow! Like everybody else, the Microsoft fixes didn’t work for me either. I “caught” the XP Antivirus 2011 virus 6 months ago, and Windows Update hasn’t worked since. Your command line was a little confusing, so I took a chance…

    People… just copy and paste both lines as one action… all of the fix fits onto one line on the start>run prompt. This fix works in 2 seconds. When I went back to Windows Update, it was already turned back on!!!! Now, I’ll download 6 months worth of updates!!!

    Thanks again!!!!

  82. Ole says:

    Amazing – Thanks!

  83. chris says:

    That was amazing.

  90. Anthony says:

    Wow, it works…don’t know how u figure this out…thanks 🙂

  91. Jeremy says:

    Hm… I’m not having the same luck. Maybe I’m doing something wrong. Just copy and paste the first of the 2 lines, right? What’s the second for?

  128. Moschops says:

    After years (over a decade now) of advanced Windows use it is still unbelievable to me that Windows spits out these errors and there is apparently no direct route to find a solution like this on their website. After many wild goose chases your solution was the bomb! Thanks for sharing.

    RondolphStreet50: Thanks for dropping by and TQ for your word 🙂

  226. TL says:

    Finally, I found something that worked. Thanks a lot! Awesome.

  227. RandolphStreet50 says:

    A thousand thousand thanks for this fix, which as Tony says you deserve a medal for also saving victims from some suspicious little $30 program called error end which on googling up the 0x80070424 error was returned in the results. “No thanks.” Even the guy who built this box was stumped, and after having suffered the worst virus/trojan invasion of my computer in over 10 years all update facilities were completely disabled, and even system restore didn’t work. I could just hear the hackers hooting over their latest prize, ready to stream through the broken gate and do their dirty worst to my innocent computer. But like the lady said, “No more he’s not!” With all indicators now green I can happily [and more cautiously] go about my online business. Everyone who has used this method should pass the word around about this marvelous little corner whence they got it, consider buying the man a drink – “I know I will!” – and, most importantly, keep as vigilant security as possible and tread carefully through this cyber-minefield with its many dangers. Happy computing to all, and to all a good byte!

  228. roger medina says:

    Wow! I was skeptical at first but this did it after I tried all the steps on the Microsoft site and nothing worked! Thanks a millions!

  229. Rob says:

    Bless you!!! If anyone knows who created the “XP Security 2011” garbage, please let me know, I would love to express my “appreciation” for the hassle his creation caused me. Some time in ICU may modify his desire to create further similar crap.

  230. Michael says:

    I had this same problem and spent hours looking for a solution. Microsoft were of no help. This fix though was simple and worked immediately…….many thanks indeed.

  231. ME!!! says:

    You are the man!!!(or maybe a woman!!) either way thanks so !#%!%# much!

  232. Bryan says:

    That worked almost too easy. You’re the man.

  233. Jeff says:

    Wow….awesome. Such an easy fix….thanks!

  234. adw main says:

    OMFG! that worked!
    i have had the problem the last 2 days. i have tryed so many downloads, & nothing has worked. i did registry clean, cleared cookies history etc. tryed a bunch of stuff – not succesesfull.

    i called a computer repair company who came out & basiclly said my computer is screwd & will need another one. the labour & work involved would heavily out weigh the charge to fix it. they did dick all – all they did wwas run malaware.

    i asked them repeatedly there must be a way to fix it. no nope not was there answer unless i wanted to spend at least $ 300 – $ 400 in labour dumoing my computer & re loading it. this did not make sense to me as they brought a computer with them to the repair. wtf? eh?

    anyways long storey short – found this site & wolla! woooo hoooo! it is working absolutly amazing!

    tryed updaing severl times & is working.

    who ever you are —— you are the best & a big THANK YOU! from langley bc canada! freaking eh! baby! 😀

  247. snakeroo says:

    Yay, after somehow contracting the Windows XP fake Security virus and eliminating it with MBAM, I was still left with not being able to re-enable my updates. But this did the trick. Thanks!

  248. A Henderson says:

    Thanks. I was dying here. Big Help

  249. Tony London UK says:

    THANKS FOR THE SCRIPT – It’s totally brilliant

    I recently had a nasty virus on my XP – after 4 hours hard slog I managed to rid myself of it but with the exception that the windows update was showing ‘Error number: 0x80070424’ and my windows security settings were showing as turned off – both are now corrected thanks to this little ‘paste the command’ fix.

    whoever you are, you need a medal for services to us frustrated XP users

    while I’m here – if anyone has inadvertently loaded a virus from a website which shows itself as a working ‘rouge’ scanner and if your system restore is not finalizing correctly – try this method to rid yourself of the little blighter.

    1 – open computer in safe mode – make a ‘new’ user name via CONTROL PANEL/USER ACCOUNT- remember to tick administrator rights for this ‘new’ user name
    2 – restart computer as normal start up
    3 – select the ‘new’ name from the different users that are now listed
    4 – a basic windows desktop should appear but the ‘rouge’ scanner should NOT be active –
    5 – now try system re store to an earlier date and restart the computer
    6 – IF RESTORE WAS SUCCESSFUL on start up remember to select your ‘original’ user name this time round – if the rouge scanner has gone your system restore has worked. Congratulations

    If system restore failed

    repeat parts 1-4 then
    5 – while on your ‘new’ user desktop – navigate to the folder or desktop where you can activate your ‘original’ users onboard virus/malware scanners. Remember that while you are actually logged on as the ‘new’ user, you do have administrator rights that allow access to your ‘original’ user names anti virus programs. Try finding them via C/Documents and Settings/ the FOLDER WITH YOUR ORIGINAL USER NAME ie Owner/ the FOLDER where you initiate you anti virus scanners ie Desktop
    6 – try to open, update and the run your anti virus scanners
    7 – if you’re lucky, the scanners should locate any malware in your registry
    8 – now restart your computer as normal
    9 – on restart, Open as the’NEW’ user
    10 – Now try system restore to a safe date before you were infected
    11 – if system restore is successful, you should now select your ‘original’ user name to see if the ‘rouge scanner’ has gone from your desktop
    12 – if everything is OK – Congratulations, you can now delete the ‘new’ user name via CONTROL PANEL/USER ACCOUNT and revert back to your original user name as normal (making sure it has administration rights ‘ticked’ of course)

    Thank you.

    I have windows vista 64 and simply registering the dll files did not work for me. I was missing the “windows Modules installer”. I found this page and followed the instructions under scenario III.

  306. Jørn says:

    paste in
    regsvr32.exe wuaueng.dll

    worked for me 🙂

  307. juli says:

    still not working…pls i need help..

  308. Antonio says:

    nothing works for me the error is still there im on vista x64 sp1

  309. paul brookhouse says:

    if none of these work, i found a fix that does it for me…… open security centre, and click ‘change settings’…. uncheck the box marked ‘use microsoft update’ and confirm the change. run update, then go back and re-apply the software by clicking the yellow box which offers updates on other products. i’m on vista ultimate pro sp1, and this is the only fix i found anywhere that actually works…. there’s also the plus point that anyone can do it, using the vista platform rather than the ‘semi-code’ in the background.

  310. jun says:

    this thing works for me! to vista users, try open start, all programs, accesories, right click command prompt and open as administrator, copy- paste the command given in the solution and press enter. GOD bless.

  311. chris says:

    worked for me:D
    thanks 🙂

  317. SirKerz says:

    tried this also:

    And still does not work!!!
    I am now in contact with Microsoft and awaiting a reply……….

  318. SirKerz says:

    Disabled firewall and tried again still did not work

  319. SirKerz says:

    mine still does not work!!
    Running CMD.EXE as administrator and pasting %SYSTEMROOT%\SYSTEM32\REGSVR32.EXE %SYSTEMROOT%\SYSTEM32\WUAUENG.DLL
    little box appears and tell me it was successfull, then try to run update but still get same error:
    Code80070424 Windows Update encountered an unknown error

    PS: running vista 64 service pack 1

  320. Tyrant917 says:

    If you’ve ever had Symantec / Norton Antivirus on your system and it was not uninstalled cleanly, it could create this error. Try downloading and running the Norton Uninstaller Tool. If you’re not sure if you’ve ever had Symantec on your system, run regedit and search for the word “Symantec”. If there are registry entries, it’s likely it was on your system at one point. After trying all the things others recommend without success, this is the solution I figured out that worked for me.

  321. dbits says:

    fantastic! thanks a mill JACkeL; I’ve been trying to fix this for weeks.

  322. Greg says:

    Awesome. Worked like a charm as soon as I typed it in (used same line without editing for my copy of XP Pro x64).

  323. JR says:

    JACkel, thx a bunch! The (left ;))ctrl och shift thingy worked great!!

  324. SUMIT says:

    thnx a lot guys running the commands in the command prompt as administrator worked for me only the command that i used was
    regsvr32.exe wuaueng.dll

  325. chua says:

    Elizabeth: not so sure about this, but should be the same. You can give a try.

  326. Elizabeth Hall says:

    My system is 64 bits and I’m wondering do I use the same thing and just substitute the 64?


  327. JACkeL says:

    I had the same error code (0x80070005) until , as Cypher above stated, I ran the command in the Command Prompt under Administrator.

    To run the Command Prompt in Admin, you need to type CMD.EXE in the Start Search box and then, while simultaneously holding down the RIGHT-CTRL and RIGHT-SHIFT buttons, hit the ENTER button.

    A dialog box will then appear that asks you if you would like to continue, which you do and therefore you will then press the continue button in the dialog box.

    The Command Prompt now appears and it is being run as Admin. Type in the command stated above (i.e. %SYSTEMROOT%\SYSTEM32\REGSVR32.EXE %SYSTEMROOT%\SYSTEM32\WUAUENG.DLL) and another dialog box will appear that will tell you that you successfully registered the WUAUENG.DLL.

  328. shashank says:

    it is not working dll is loading but the call to register server failed with error code 0x80070005

  329. Tim R says:

  330. Cypher says:


    works YOU MUST – RUN CMD.EXE as admin then paste the above in

  331. feilong says:

    hi man thx it works

  332. Chris says:

    FIX FOR 0x80070005!!!

    I just tried opening up the command prompt (as admin) and entered the commands they told you run with a space where the line break is and it worked fine for me..

  333. Gerardo says:

  345. Henk says:
