error code 800B100

Please help I have Windows Vista and recently I have an error code 800B100
windows cannot search for updates! I have spent the last week trying to fix
it. I have been reading some of the other peoples questions on the same
subject. And tryed deleting software destribution down loads. And it seems
nothing seems to work. Ive noticed several people have had the same problem
and nobody knows what the error code even is! Can anybody help

0x800B0100 TRUST_E_NOSIGNATURE No signature was present in the subject

Is that the error code, Sheila ? If yes, then try this:

Open an Elevated Command Prompt -
Click the Start button. In the Search box, type Command Prompt, and
then, in the list of results, *right-click* Command Prompt, and then
click Run as Administrator. Follow the prompts.

At the Command Prompt type in and press Enter after *each* command
[NOTE the spaces, please]

net stop cryptsvc
ren %systemroot%\system32\catroot2 oldcatroot2
net start cryptsvc
regsvr32 wintrust.dll /s
exit

See if the system will update now.

I've had the same problem (with Vista Ultimate 64-bit) since ~8/23 that
Sheila described. I attempted your suggested work-around and received the
same error from Windows update.
