Service registration is missing or corrupt

I have the same issue on my XP Professional with SP3

Hi Wasantha,

1.       Which Fit-it are you referring to?

2.       Are you not able to install some specific updates?

You usually get this error while installing software updates. If Microsoft finds some problems in the digital signature of the update is when you usually get this error.

Have a look at this and see if that helps:

Please reply if you need further assistance.

see if Bits service is disabled, if so this post may help, it had me in circles for days

Thanks-The Fit-It apparently is no longer functional for Windows XP Pro---The updates in question popped up a few days ago(a screen shot is attached)--This issue is that I have succesfully downloaded and installed those 3 updates 3x now--BUT--the yellow icon keeps insisting that those same 3 updates still need to be installed--when I checked the history all have been installed--when checking furthger I then got the message about corrupt service registration--although that message was from Fix-It which leads me to believe that is not the issue----please advise--thanks

Hi,

It did not work for me. Windows update just keeps running without showing me anything.

Fix it gives me the following error:
