Ok :) Then what is the issue?

If this connects, you are good to go and can use the kit.

In device and printers it should not be in unspecified it should be in devices correct?

It does not matter as long as it works. It could be a simple Windows 10 "issue".

Under the same Target pull down, there is Erase Chip.

Does that erase the chip (internal flash inside the CPU)? Note that this will erase any program that is currently loaded on your kit.

Assuming that this will work ok. Moving forward, pretty sure you are good to go. Proceed to code up your custom code, generate the .hex output file and use this same programmer tool (STLink) to load in the .hex file and Target -> Program to test it out.

Also, one last thing to test is:

Target -> Connect (if you not done this already) -> ST-Link -> Firmware Update

This procedure will then ping the first CPU on your kit and report the version of the firmware. Also, the tool will go onto the internet to fetch the latest firmware for your kit.

What are the reported versions? This procedure is a bit goofy and may request if you wish to go back to an older version of the firmware. Do not do this if requested. Only proceed if the new version of the firmware from the internet is higher than the version on your kit :)

Allow the programmer to reflash the firmware to be the latest (if necessary) - do not interrupt the process -> then Target -> Disconnect. Target -> Connect -> ST-LINK -> Firmware update -> now the firmware should be reported to be the latest.

What does Device Manager report after this procedure?

Either way, if ST-Link can find the kit, you are good to go and proceed with your code development.

Step 20 of your posted PDF document shows the STLink in same location :)
