Windows performance (either one) isn't hampered in any major way. By dual-booting, each OS believes it is the only one there. Only one runs at a time and is oblivious to to the other. It isn't like running a virtual machine where one operating system is running in a virtual environment within the other.In the case of dual-booting Windows 7 and Windows 8.1, the Windows 8.1 bootloader will load and bring up the option to boot to Win7 or Win8.1. If Windows 7 is selected, it's bootloader is effectively chainloaded and the remainder of the boot process progresses as if Windows 7 is the only OS on the system. If Windows 8.1 is selecte, it just starts to load the operating system as usual. Because of this, the overall boot time is slightly longer. There are also two operating system partitions (one for each), so there is additional storage space consumed and applications that you want to run in either environment need to be installed in each one.No matter which OS is chosen during boot, it is running on bare metal the entire time and its performance reflects that. With the exception of boot times, it would have the same performance as if you had each operating system on its own hard drive that you swapped out as necessary.

If the computer properties indicates that Windows is activated, there is nothing to worry about. The servers have confirmed it is a valid installation that used a valid product code. If activation has not yet happened for any reason, there will be a notification of how long the user has to activate Windows along with a link to do it immediately. If there is a problem during activation, it will provide information on how to contact Microsoft over the telephone to do the activation.I'm not sure I fully understand what you are looking for with the last part, but product codes and activation keys are NOT tied to the installation media. The closest you can get to any kind of ties between the two are that certain product codes only work with certain editions of the specific product. For example, a key for Windows 7 Home Premium will not work with Windows 7 Ultimate installation media. Also, OEM, refurbished and retail product codes are not interchangeable.

It's no big problem. You just need to have two or more partitions on your system. Just insert the cd and restart the system. Windows 8.1 will boot from the cd. During the installation click custom installation when it asks to do so. Then select a partition other the then the drive in which Windows 7 is present and finally install it in the normal way. At every boot it will ask whether you wanna run Windows 7 or Windows 8.1 .Your system needs to be 64 bit in order to install a 64-bit operating system but as much as I know every system manufactured in or after 2008 is a 64-bit system and can run both 32 bit and 64 bit operating system. If you are having a 64 bit system you can run 32 bit windows 7 and 64 bit windows 8.1 or any other combination. There is no restriction for that.

Thanks. Huge effort! Thanks again. Does dual boot install ( say win 7 and 8.1 ) hamper the windows performance in any ways ( speed , RAM , booting , risk of hanging ) ?Please also try to answer as new answer so that your answer is enabled to be chosen as best answer , because currently your answers in same thread of another respondent
