Error Code 800B0109 stopping Windows Defender updates

[EricCarwardine]

Hallo;


I have previously been a member of this forum but lost all record of my Username/Password in a rebuild of Windows 7 Professional 64-bit.


Attempts to update Windows Defender are consistently returning error code 800B0109


I've followed the procedures outlined in https://support.microsoft.com/en-gb/help/10164/fix-windows-update-errors but hit "Access is denied" while attempting to apply, in a .bat file:

Ren %systemroot%\SoftwareDistribution SoftwareDistribution.bak

See attached file.


If it's relevant I've set Owner to "Everyone" with Full Control permission as part of fixing other errors.


And added "Take Ownership" to the context menu.


Is there a way to fix 800B0109 error without spending a lot of money on programs that don't do what they claim?

Hi EricCarwardine,

You have to stop wauserv & bits, rename, start wauserv & bits

net stop wuauserv
net stop bits
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
net start wuauserv
net start bits

or run my OneDrive batch script
ReName Software Distribution Folder .old .bat

If you are having Windows update problems, run AutoSURT64 or from my footer and post CBS folder minus the .cab compressed files zip & upload. upload limit for RaR or Zip is is 4 MB.
AutoSURT64 is M$ system update readiness tool SURT plus is copies CBS folder to desktop including CheckSUR.log. Automates the process for you! CBS.log & CheckSUR.log are necessary to diagnose issues with Windows Update.

Hi Eric,

based on your screenshot - there is an error prior to the 1 you quoted.
It appears after Service pack 1 was installed, rather odd as your using MR7.

The code in itself means theres an invalid certificate, please check the date and time on your comp
Is this the only update your having a problem with???

Also be advised Windows Defender is not a total AV you should at least be running MS security Essentials
and both will NOT be supported in a few weeks time.

REVERSE the permissions change you made
