Unfortunately, you will need to reinstall everything from scratch. All games and programs will have to be reinstalled as they create registry and system files that are needed for the program to work correctly.
Most SSDs come with cloning software. My 840 took 8 minutes to copy the Windows install over and was immeidately useable.
What exact SSD did you buy?
Remove power cable from hdd so that its not detected during windows install. Once windows is installed you change the location directory for all your personal files such as music, documents, photos, videos. After that install whatever you want to your ssd and all other programs but you will need to change default installation directory.
Connect both the original Windows HDD and the new SSD. Boot into the old drive (Windows)
Make sure you update the BIOS on the M500 http://www.crucial.com/usa/en/support-ssd-firmware
Then download Minitools Disk Copy (freeware) and http://www.minitool-drivecopy.com/download/minitool-drivecopy.exe
Copy the old Windows installation over to the SSD.
Shutdown. Remove old HDD.
Boot into new SSD and install any software Crucial use to manage the SSD.
Once you are happy with the SSD install, reconnect the HDD (old one) and boot into the SSD again, format the old drive and use it for storage etc.
Another approach is to use the SSD via Intel Smart Response. This will keep the install on the old drive and use the SSD for cache.

Fresh install has the best end performance.
