NUM Lock goes on and off by itself in response to unrelated keystrokes

Update on this issue -- and I'm the OP.

I've been on the phone with Dell tech support (which I purchased along with my new PCs).  One of the knowledgeable techs explained something to me that I hadn't known, but it's not yet a solution to this problem.

If I (or you) have Num Lock on, the number pad on the right part of my keyboard will type numbers.  When it is off, some of the keys will position the cursor around the document.  (You can see the arrows and "Home" etc. on the number pad.)  Well, that's the basic starting point, and I always set my PCs to turn Num Lock on.

However, when I'm in a document with Num Lock on, and I hold down Shift, then the number pad works as if Num Lock is off.  (With Shift down, the number keys won't type numbers - they will move the cursor around the same as if Num Lock is off.  As soon as I let go of Shift, the number pad works to type numbers.)  While I was on the phone with Dell, I tried this in an Excel spreadsheet, and he was 100% correct.  That's not at all a problem and is good to know.

The problem I am having is that, in the new PC with new keyboard, every time I hit Shift or the Win key with any other key, I get an immediate warning at the top of my display screen that Num Lock is turning Off or On.  Over and over.  That's what I need to get rid of - this constant showing me that Num Lock is temporarily off and then back on.  It may be accurate, but it is absolutely maddening.  Who needs this?  How do I get rid of this constant top-of-monitor popup?

Thanks.

@glnz Since I dont like those keyboards i would suggest

Logitech K800 or
UNICOMP IBM Model M Buckling Spring Keyboard USB

https://www.ebay.com/itm/275393700309

I prefer capacitive keyboard which is a 35 year old design which is why PS2 keyboard option remains even today on precision workstations. The original IBM PC from 1981 used this design.

Model M buckling spring keyboard has the same mechanism, feel and layout as the original IBM Model M keyboard, but with a slightly smaller footprint. The buckling spring key design these keyboards have been prized by computer enthusiasts and robust typists because of the tactile and auditory feedback of each keystroke. Still made by  UNICOMP

In 1996, Lexmark International was prepared to shut their Lexington keyboard factory where they produced Model M buckling-spring keyboards. IBM, their principal customer and the Model M's original designer and patent holder, had decided to remove the Model M from its product line in favor of cost-saving rubber-dome keyboards.

Rather than seeing its production come to an end, a group of former Lexmark and IBM employees purchased the license, tooling and design rights for buckling-spring technology, and, in April 1996, reestablished the business as Unicomp.  People still pay hundreds of dollars for these keyboards on ebay because they don't know that Unicomp still exists today.  They will even repair your original keyboard if its not working.

Buckling springs originated in 1981 IBM’s mechanical keyboard as a fundamentally different kind of switch mechanism. Featuring a coil spring that sits between the keycap and a pivoting hammer that collapses when clicked, the spring provides a loud, tactile feedback.

I have a Microsoft wireless keyboard (and mouse combo).  I get the number lock on or off notice and I haven't found a way to eliminate it.

The Microsoft keyboard is sort of a throwback to older keyboard feel and layout.  Not IBM 3174/3270 but close.

fireberd - do you get that pop-up notice on your screen as often as I do - constantly as I use key combinations for normal work? 

Or only occasionally?

In my case, it's happening at top center of the screen and it is way too noticeable and incredibly frequent.

This is on two different (maybe three) PCs with the KM5221W wireless keyboard.

Am I the only one being annoyed by this?  No one else cares?

Num Lock and Caps lock both display on or off when pressed.

The message is displayed in the lower right of the screen.

fireberd - can you post those search links here about the vendor-specific settings?  I couldn't find anything relevant, and I'm still speaking with Dell about this.

Also, what links prompt you to write "Supposed to be a vendor app for this" ??  Would be great to see that as well.

Thanks.

I did a search for this and what I find, its vendor specific if it displays and the location on the screen.

Supposed to be a vendor app for this but didn't find  what it is and/or where its installed for Dell (or in my case, Microsoft).

All my info is from a Bing search for "num lock display on screen".

I posted the how to disable the on screen display on another computer forum.  I'll see what, if any, responses I get.

Glad to hear you found a workaround.  I came up empty on the other forum.

I can understand your small business IT staff pain.  I was fortunate to have a full staff at headquarters.  I'm a retired LAN/WAN Network and Hardware help desk manager for SSA.
