Hello Ravindra,
If you are in a Fortune 500 or above company I would find out if there are any changes planned for image used to install the Microsoft OS on desktop's, laptop's, and mobile devices.
Monitoring Microsoft and SAP product compatibility is an ongoing process. Both SAP Portals and ABAP Systems have unique requirements for consuming WEB GUI sessions. As Desktop applications change from Browser level’s to Microsoft Office transitions from Office 2010 to 2013 we need to ensure our backend systems won’t experience integration issues with those and other external third party applications. SAP will continuously update the SAP GUI client components like SAPSetup.exe, Core Patch levels, and Add-On’s. Any Microsoft updates can require SAP to deploy updates in order resolve compatibility with newer Microsoft OS 8.1 and applications like Microsoft Office 2013 or Office 365.
Talk with your BASIS Administrators as well because there are thresholds limited by kernel and SAP_BASIS component which update Mimes and Templates.
Cheers,
Dan Mead
