Hi Gene,

What can I say???, you are a "Legend". I just ran your command and it worked perfectly. All items are now speaking normally and I am able to work in Chrome, IE and Edge. Even context menus and the Taskbar icons read as they should.

Again, many thanks.

hi Paul

I had the same problem on a blind members computer saying the same sort of thing. I put the instructions up on my website so it would fix it, but some how some one is re diverting it to another site and it has taken over now even the links to the same site. so unless i can fix the problem i might even kill the domain it goes to.

I would have to check also what model she had but is a laptop by asus and is on windows 1607

I still have a copy on my computer with the instructions but you might need a sighted person to do it.

hers is the first i have come across that has done that. most times you just install nvda and it works.

the instructions are below.

Troubleshooting - NVDA says “unknown” or “pane” in all of your browsers, Mozilla Thunderbird email client and other places If for some reason you have problems with NVDA saying “unknown” or “pane” check for the following symptoms:

In all of your browsers, or the Mozilla Thunderbird email client, no matter what you do, you still hear “unknown” or “pane”.

In the browser, email client and other menus you notice you cannot get into your menus, or you are unable to use the quick navigation keys • When you have been told the page is loaded and notice strange behaviour • Mozilla Thunderbird saying unknown while you try to navigate it • Your applications key does not work with it being spoken out and other strange behaviour in Windows • The running applications icons are not being spoken out It might be a good idea to do the following:
Please note: If you are hearing “unknown” or “pane” (as discussed above) NVDA might seem like it is still working properly but it may not be completely in Windows and other programmes.
You could try the following solution which will allow you to re-register your dll files in case they are causing the problem.
Press the Windows key then type the following into the search box. Type in “command prompt”. Once you have located command prompt, in the search results, press the Applications key to bring up the context menu. Arrow down to select “run as administrator” and press the Enter key. This will take you to a command prompt window. This will not be spoken out. You may need sighted assistance for this.
Type in the following command
for %x in (c:\windows\system32\*.dll) do regsvr32 /s %x This should re-register all components in the system32 folder.
When it is finished, you can close the command prompt window with the Alt + F4 key. You should notice now where NVDA was saying “unknown” as in some examples given, NVDA should now read the icons in the running applications area of Windows, speak the content of the webpage and menus, and also in Mozilla Thunderbird and other places in Windows including the Windows applications context menu.

Hi All,

Got a new desktop, never used before and first thing I did was to install NVDA latest version. After navigating around the main desktop and some of the windows 10 settings screens I kept getting NVDA announcing, "Unknown" all the time as I tabbed and so on. I disabled any lock screens, screen savers and the like. I also uninstalled and reinstalled the video card which is an Intel HD 630.
After doing all the above I uninstalled and reinstalled NVDA but still no success. Even when I go onto the Taskbar and arrow along it, NVDA just announces, "Unknown". On the main desktop screen when I open up a context menu there is nothing, NVDA doesn't announce any of the menus options, not even announce that the menu is in fact open.
Just wondered if there were any suggestions as to what might be going on here.

Many thanks for a great list and wonderful program such as NVDA.
