mk520 keyboard sporadic in windows 10-whats better

I've been using Mk 520 wireless keyboards for a while. Very little problems. I recently customized a new computer and also installed Windows 10.  The keyboard is sporadic at times as is the mouse.  I anticipate it might be the keyboard.
Besides the keystrokes being "delayed" every so often, in outlook, the Shift-Select doesnt work sometimes. I found that if I double click the shift, then double click the control, then double click the windows keys, the functionality returns.
I dont know if these things are related or not (sounds a bit too hocus pocus to me ).  Are there any settings someone can think of , or, is there a better Wireless keyboard out there to consider?

Are you using a laptop with a docking station?

I have a different model Microsoft wireless keyboard on a Dell Latitude 5300 connected to a docking station and it falls asleep all the time so that it doesn't register the first key pushed. I am constantly having to retype passwords because of it.
check the usb power settings as shown here, and Uncheck to turn off the Allow the computer to turn off this device      to save power option, and clickOK      button :  https://www.hamoperator.com/Fusion/FusionFiles/K9EQ-Fusion-PDF-0023.pdf
I ran into something similar not too long ago

Replacing batteries resolved the issue. Give it a try if you haven't already

heh folks -
no docking station, just straight desktop.
new batteries,
USB2
no sleep setting

I'm ready to try another MK I have around. perhaps its the keyboard.
That said, I do have a laptop that is connected to another K520 that I use.
I thought that might be interfering, but even when that laptop is off, I still have the same problem.
you can also test this keyboard on another system - to be sure where the problem lies - with keyboard, or PC
Did you check for software/firmware upgrades?
Where do you have the placement of the USB receiver?  (i.e. front or back of PC)
Status of this keyboard on the other PC?

dont have another pc...
USB is on the back of the PC about 4 feet as the crow flies. Front usb is USB3
no upgrades since a few years back.

Will check new keyboard in a bit
Have you tried the front USB ports?  Does it have any hidden USB ports (Behind panel)?

Revisiting the original post, "I found that if I double click the shift, then double click the control, then double click the windows keys, the functionality returns." makes it sound like you might have sticky keys.  It might be worth popping off a few keycaps and using alcohol to clean the key switches.  It's possible to simply wash the whole thing, either in a sink or on the top shelf of your dishwasher, but you'll want to let it dry for several days before attempting to use it again.

Anyway, alcohol and a cotton swab might be a quick fix.

found the issue!!
The desktop is under a standard modular desk, however the usb is about 3 feet away. Also, there is a router and a wifi scanner close by.
I extended the USB port with a usb extender I had and placed it on top of the desktop. Ironically enough the extender was a Logitech extender (duh!) .
No problems since with keyboard/mouse delays or shift key usage.

Thanks everyone!
