Windows Update Cannot Be Enabled Error 8007277b: A System Call Has Failed

I've tried to turn on Windows Update through the action center which I couldn't. Then I tried to run it by starting it from Services which led to to this error : " Windows could not start the Windows Update service on Local Computer. Error 0*80070057: The parameter is incorrect". I also cannot run Background Intelligent Transfer Service, with similar error. Next I tried to run it in cmd using "net start wuauserv" which i got this answer for: "A system error has occurred. System error 10107 has occurred. A system call has failed". Also I don't know if it's relevant or not, but when i tried to restart the windows, desktop couldn't run and i only had a black screen with Win98 bars and got fixed by restarting one more time. Anyone know how to fix this ?

Thank you.

Roll up your sleeves & cross your fingers...

[You will want to print these instructions for offline reference. You must complete all of the steps in one (1) uninterrupted session - allow a minimum of an hour. If a Step says to reboot, reboot!]

1.  Close all open applications (i.e., anything with an icon on the taskbar).

2. Download/run the Norton Remove & Reinstall tool (NRnR.exe) per the instructions on this page:

NOTE: Do NOT enable or install any Norton Add-ons or toolbars (e.g., Norton Anti-Phishing) just yet.

3. Manually and repeatedly run (Norton) LiveUpdate until you get a "no more updates" or similar prompt.

4. Download/run the appropriate scripts from the following Trusted Source (my colleague IE MVP Kai Schätzl):

Note => The scripts are good for IE9, IE10 & IE11, too!

Tip: The file named contains both of the scripts below (plus a third one you will NOT use).

5a. Close all open applications (i.e., anything with an icon on the taskbar) then double-click on the file named ie8-rereg.32on64.cmd to run the script.

5b. Close all open applications (i.e., anything with an icon on the taskbar) then double-click on the file named ie8-rereg.64on64.cmd to run that script then reboot.

6. Re-assert Internet Explorer as the default Browser in the CUSTOM (<=important!) section of Set Program Access and Computer Defaults. [1]

7. Reset Internet Explorer per the instructions on this page =>

Note=> For optimal results, check the Delete personal settings option.

8a. Open Internet Explorer (only!) to [ignore the title & Symptoms].

8b. Ignoring any "Not recommended" or similar warnings, run Fix It 50202 in DEFAULT and then AGGRESSIVE modes. [2]

9. Reboot then test Windows Update functionality.

10. Reply to this post with a status report.

Good luck!

[1] After we've finished this thread, feel free to reassert Firefox as your default if you wish.

[2] Full Disclosure: Running the Fix It in AGGRESSIVE mode will delete your Update History but not the list of Installed Updates.
