access time machine back up from different pc

If this is not the appropriate place for this question, I apologize. However, I have an Airport Extreme with Time Capsule 3 tb model A1409. I do not have access to my Mac Mini for several weeks and am forced to borrow a PC laptop (ugh) from a friend until next week when I will be able to replace the Mini. I need to access particular documents in Time Machine and am hoping there is a way to do so using this laptop. The Airport has not been on since I unplugged the Mini from it. Thank you in advance for any and all input.
