How are you connecting? For transfer of video, you have to use firewire. USB will not transfer video on a model that old. USB was only used for transferring images off a memory stick, if your model had that capability. There are 3 names for firewire, which are firewire, IEEE 1284, and Sony calls it i.Link. Your camcorder probably has a 4-pin i.Link port. You also need a firewire controller in your computer, and a cable to connect the two. Most controller cards use 6 pin connectors, so the most common cable is a 4-to-6 pin model.
Then you need software that can see and understand the video. Windows Movie Maker could do so, but I haven't tried it on Win10. You can control the camcorder directly from the software if it works properly. There is also a possible need for drivers, which almost certainly were never updated for Win10, but most video editors should see the camera directly over firewire.
Or you can use the SD import hardware mentioned by Starrysky, although you will lose quality by using composite video that way. The upside is those adapters can be found very cheaply, and are much easier to use. Your camera should have the required ports (RCA jacks, yellow red and white) or possibly a single connector into the camera that splits into the three RCA jacks. If it requires such a cable, it would have come with the camera.
