Windows shortcuts inserting last stroked key

Question

When I use any of the shortcuts in my system, it first insert my last stroked key belongs to that shortcut. I also tried 4 diffirent keyboard models in my laptop, but its still same.

For example if I copy "Hello World!" text with CTRL + C and then paste it with CTRL + V, it writes V key before the copied text, pasted text becoming "vHello World!".

Another example is, if I select "Hello World!" text with CTRL + A key and then stroke SPACE (or any key) in my keyboard, it writes the A key.

This is so annoying... Here is my hardware and software specifications,

• System Model: HP ZBook Studio G5
• Operating System: Windows 10 Pro 64-bit (10.0, Build 18363)
• BIOS: Q71 Ver. 01.11.03

Edit:

• My problem is not happening in safe-mode.
• I've also tried to disable all of my start-up applications.
• Toggle keys and Sticky keys are disabled.

As the problem doesn't arrive in Safe Mode, this indicates that some third-party application is responsible for this weird behavior. Here is how to find that application.

The tool to use is the free tool Autoruns for Windows.

Autoruns shows all the programs configured to run during system bootup or login in its "Everything" tab. You may turn off startup items with a click and return them later with another click. You may avoid listing Microsoft products by using the menu Options > Hide Microsoft Entries, Hide Empty Locations and Hide Windows Entries.

I would suggest turning off startup entries in bunches and reboot, drilling down to the startup program that causes this behavior. Once identified, it might have some setting that can avoid the problem, or can be left out of startup and only be invoked when required (verify that once invoked it does not add another startup entry, but such can again be disabled by Autoruns). Start with products that may pertain to the clipboard.
