Windows update (SQL update?) has corrupted svchost

[Guest]

I beleive that it is an SQL update that has caused my svchost.exe process to
give an Application Error every time I start my computer:

"svchost.exe - Application Error

The instruction at "0x745f2780" referenced memory at "0x00000000". The
memory could not be "read"."

Also, explorer has frequently started hanging after this incided and then
forces me to hard shut down my PC. Is there a solution to this problem?

Workaround: Change the default from Microsoft Update to Windows Update: Go
to Microsoft Update > Click on Change Settings in left pane > Scroll to
bottom of page > To Stop Using Microsoft Update > Disable Microsoft Update
software and let me use Windows Update only (check).

With Windows Update as your default, you will need to check in at Office
Update to keep your Office applications fully patched:
