Changes not saved while uploading in sharepoint 2010

                                         Steps for resolution:

The error was due to documents getting upload by Microsoft Office Upload Center. Microsoft Upload Center is and add-on that gets install with Office 2010 suite.

 This probably is saving document to its drafts and not letting it upload the changes.

Ø  To fix this, what worked for me was to :

1) Check-Out the document you wish to edit.

2) You will be prompt for saving it to your local drafts.

3) Enable it (check that box) and click OK

4) Now edit the document and save it.

5) You will be asked to check in your changes

6) Put in the comments and click OK

Ø  To disable the Microsoft Office Upload Center and try saving your document.

Open task manager and kill MSOSYNC.EXE and OSPPSVC.EXE
