Apparently this is a common problem, where on Windows systems you do not see any interfaces:
There are a couple of things to try:
1. If you are using the npcap driver, sometimes the driver 'service' is stopped by antivirus or Defender or something.
The fix to this is simple: first open a CMD prompt - but make sure you run CMD as Administrator. It should have you at the C:\WINDOWS\system32 prompt:
OK now issue the following command in that window:
sc query npcap
You will likely find it to be stopped:
So now turn it on with:
net start npcap
Be patient, it will take about 30 seconds:
And then hit F5 on your Wireshark application to refresh the interfaces, or restart Wireshark and all should be well:
2. Try running Wireshark as Administrator.
3. Try re-installing Wireshark (don't worry your personal configs will be saved unless you explicitly remove those as well - I would not do it!).
Let us know what other fixes you find in the comments below.
Hope this helps.
