Updating Visual Studio Community 2015 SP1 never completed

Hi All,

I have updated Microsoft Visual Studio Community 2015 with SP1, after downloading the SP1 and installing, and then the process goes to"Configuring your system. This may take a while" but this process has not yet finished even after 2 weeks. I though this process takes very - very long.  Is there any solution ?

Thanks.

Regards,
