I have windows 7 professional x64 and have a terrible time downloading, much less installing updates error messgae 80070002
I sometimes have success by deleting the Software Distribution folder in C:Windows and then rebooting and then setting my computer to auto install at the next closest hour
When I was checking Component Services to see what might be running that didn’t need to be and vis-versa, I found that in trying to start mcx2svc, I found the same error message and found that it had strange dependencies for being the tv extender for WMP.
I have read, saved and tried about 20 different fixes. Oh, I have never been able to access anything manually from microsoft since buying W7
