I've got my new laptop for three months, it has worked perfectly fine changing keyboard language by Win + space. But starting from yesterday, I can no longer change it. When I press Win + space, nothing happens. I tried Alt + Shift and Ctrl + space as well, no response. I tried changing the setting of keyboard shortcut to Alt + Shift, no response. I tried turning on the language bar, it doesn't appear. I tried getting Windows updates, the problem persists. I tried getting driver updates from hp, the problem persists.
What can I do? Is it a Windows problem or hp problem?
p.s this is windows 10 on a hp laptop
