Windows XP fails all updates error 0x80240020 July 13, 2006 11:12 am

One machine I’ve cleaned of viruses and was trying to get the latest security patches has been giving me huge fits of grief with the WindowsUpdate.log growing large with error 0x80240020. Finally I discovered this registry change that seems to have fixed the problem!

Open the registry editor and navigate to:
Check for the existence of a Notify_Disabled subkey under Winlogon. If that
subkey exists, delete it.

Now, navigate to:
Check for the existence of a SensLogn subkey. If SensLogn does not exist,
you will need to add this missing key and its values. Copy/paste the
following, between but not including the two sets of asterisks, into Notepad
and then Save as a file named SensLogn.reg
NOTE: the [HKEY_LOCAL_MACHINE\SOFTWARE\……\Notify\SensLogn] line in this
post will wrap to two lines…it needs to be on one line in Notepad. Also,
ensure that you have the blank line at the end.



Once you have created and saved the SensLogn.reg file, double-click on it,
then click on Yes when asked if you want to merge the information into the
registry. Restart your computer for the changes to take effect.

This ( start then run and type PROXYCFG -U and press enter ) might have helped. See also, also, and also. And had I read this more closely this could have been solved yesterday.

Hey, that text document did not work for me so i made a batch file that does the trick. Others may find this useful.

Copy and paste this into notepad, then save as, under the file type drop down pick all types, and make sure to name it something.bat
