Hi Praseetha,
I know this isn't your fault and I'm guessing it wasn't your decision but the removal of WET is an absolute travesty. I have used it on many occasions to transfer files and settings between PC's and in fact used it to import those settings to a new PC. A colleague of mine is looking to wipe his 8.1 machine and rebuild it but instead of that being easy he now has to backup a different way.
Utterly shambolic.
