I clearly did not think it all the way through, so please hear me out.

I installed ubuntu through the exe installer that i got from the main website onto my laptop. My laptop has never been formatted, and has only 2 partitions, one in which windows and ubuntu is installed on, and the other one that contains the backup that is setup by my bloatware and cannot get rid of, and does not have enough space for all my crap that i want to keep. Now i want to uninstall unbuntu, and hopefully keep windows. is it possible?
