I'm still a little unclear - are you looking to see if you can, in some way, 'transfer' your OS to the SSD without either of the following:
- reinstalling the OS ?
- or, using imaging software such as Acronis True Image ?
These two options are pretty much your only options, since there isn't any way to manually copy & paste an OS from one drive to another - an OS requires additional drive alterations to its destination drive. There are also hidden and critical OS structures e.g. the Registry.
If you don't have access to your OS install media (DVD/USB etc) and/or your additional installed programs then you will still be able to use imaging software but only providing the size of your current C Drive/partition is smaller than your SSD...
