Time capsule on a PC

You'll have to find a driver that lets you read Mac files from a PC, there are a couple around. Google will be your friend. Try "read Mac files on PC" or similar.

Then you'll have to manually navigate the TM backup structure to find your files, there is obviously no way to actually do the whole TM "back in time experience"
