Hi Kahini-
I'm Kevin B. Independent advisor and a Windows user like you. I do apologize for the inconvenience about your keyboard layout, let me help you sort things out.
Have you check on the control panel?
Open Control Panel by pressing windows key and typing control panel.
Go to Clock, Language and Region section click Change input methods.
Click the Options link.
Click Add an input method.
Select the Dvorak layout, click 'Add'.
Save.
Click Advanced settings left of 'Change your language preferences'.
On the 'Switching input methods' check 'Use the desktop language bar when it's available'.
Click 'Options' and set options (e.g. Docked in the taskbar and check "Show text labels on the Language bar" box).
Click Apply then OK.
Hope this will help and have a bless day!
Stay safe Kahini!
Thanks.
Kevin B.
