Below steps can be used to hide the markups from the MS word document 2010.
Step 1 :
Go
to Office button > Word Options > Trust Center > Trust
Center Settings > Privacy Options.
Step
2 :
In
the Document-specific section, clear the checkbox for "Make
hidden markup visible when opening or saving".
Just
remember that it's now up to you to look for markup before you send
the document to anyone else.
If the above option is not working, I have written a article that shows steps to create a macro in office 2010. This will help to change the default view to "Final".
