Windows 10: How to veriy Serial ports are installed correctly and working on Windows 10

How to determine the serial ports installed on my new computer are installed correctly. I need a serial port to connect to a Vinyl cutter and it is not responding with the software and I can't seem to find an easy way to determine how to Troubleshoot the issues.

Windows 10 serial on OEM


So I'll summarize steps made...

1. Saved serial number (taken with Belarc Advisory) from preinstalled (half chinese language) Windows 8.1 (don't know exactly the version, suspect Windows 8.1 with bing) on tablet
2. Formatted tablet
3. Tried to make a clean Windows 10 (HOME, HOME N and also PRO, everytime with the same result) install with ISO taken with MediaCreationTool, during install (and also after completing installation) it says that the saved serial is not valid
4. Tried to reinstall Windows 8.1 (ISO taken with MediaCreationTool again) HOME, it says that the serial is not valid

So i suspect that the saved serial, is from a WINDOWS 8.1 WITH BING OEM version and this kind of ISO is not accessible/downloadable anywhere (at least I can't find it, any suggestion?)

Still not tried SHOWKEY with that serial, I am in office now, and the serial is saved on a usb pen at home, will try this evening.

So I'm stucked but if everything is like I suspect, it's incredible. If I have a tablet/notebook/netbook with Windows 8 preinstalled, it seems that I can update to Windows 10 without problems, but if I want to make a clean Windows 10 install that serial is not valid...

Hi John,



Welcome to Microsoft Community and thank you for posting your query.



Based on your description, the issue seems like HooToo USB port driver is outdated. Let’s try simple steps and check if this help.



I recommend you to update the HooToo USB port driver and check if this helps. Follow the below steps.

• 
  Press Windows key + X and click on
  Device manager.
  
• 
  Click on Universal Serial Bus to expand and right click on the port device and click on
  Update.
  

If the issue still persist, I suggest you to go to the USB manufacturer website and install the driver for Windows 10. If the available USB driver is not for Windows 10, try installing the driver in compatibly mode and check.
