Just like we can check COM ports in windows 7 or lower , by going to

Control Panel >> Device Manager >> Ports


How should we check it in Windows 10?

    By going to device manager? What makes you think it changed? You could do this in Windows 8 and Windows 8.1

    Still not answered for me. The ports do not show up even as hidden devices. This may be a policy issue. Feb 28, 2019 at 16:40

I had the same question and I found this page. And the answer is in @zipzit's comment. So I post it as answer here:

To see "Com Ports" in Device Manager in Windows 10 you should select "Show hidden devices" in View menu.

    @BlueClouds maybe it is shown as Ports (COM & LPT) Sep 23, 2018 at 8:24

    Nope, Ports not shown even after "Show hidden devices". Jul 19, 2020 at 11:03
  • Same here, no Ports shown after "Show hidden devices". Aug 17, 2020 at 16:58

The Device Manager still exists in Windows 10 and should show this. It has not really changed at all between versions.

Open your Start Menu and just type in Device Manager, and it will come up.

    Device manager is just fine. But that's not the question. Where are the COM ports called out? I can't see them in Win10... Oops... found them. Device manager has a thing "View Hidden Devices" You have to specifically select that before the Ports (COM & LPT) are even visible.

  • The proper path to Device Manager is: Open RESOURCE EXPLORER (Win+E), right click on THIS COMPUTER, click on DEVICE MANAGER Anyway on my Windows 10 the number of each port is NOT shown here.

  • @jumpjack Why do you think that is the "proper path"? What about Win-R, devmgmt.msc ? May 31, 2017 at 22:28
  • The win+R is a shortcut for advanced users knowing what an executable is. A standard user "just clicks". :-)

    Even easier is Win+x, m. Feb 28, 2019 at 16:44

I am using Windows 10 21H2 and before @Mahmood Dehghan's answer, I had to go to Device Manager's "Advanced" menu and "add legacy hardware" for communication ports. Then the View->"Show hidden devices" answer would work.
