"Failed to connect to a windows service" error message

[willzx125]

I am aware this a problem that has been addressed multiple time on this forum and others but am unable to come up with a solution from previous posts.

I am running Windows 7 Ultimate x64, and have been for years.

I have had no problems previously that I was unable to fix.

This morning when starting up my pc I got the error message "Failed to connect to a windows service"

In addition it has defaulted to windows classic theme and I can not re enable Aero.

I looked at the Event log but it is simply beyond my level of understanding how to address the errors. Also all errors shown seem to be relativity longstanding/ recurring.

I have tried all the common suggestions I could find and none have fixed to problem.

Please can you help

Thanks
Will
