From what I have googled, Cision is a Software & Marketing company. You may have gotten a Company pc/laptop (refurbished most likely)
Can you post some more technical info on your computer like Brand/model??
Either way you may need to create an installation medium using the Media creation tool from Microsoft in order to get a fresh install.
What you have right now, is a specific system made for this company.
Any chance to get around that login?? (Don't know if you have tried anything else yet)
