Hi ,
I'm Dyari. Thanks for reaching out. I will be happy to assist you in this regard.
I have tested it with a Task Scheduler and it worked for me. Follow the instructions and let me know if it works for you too:
1-Click on Start > Type taskschd and hit enter > Create a New Task.
2-In the General tab, give the task a name > Under Security options, select Run whether user is logged on or not and check Run with highest privileges.
3-Go to the Triggers tab and click New > Select At log on under Begin the task > Set it to trigger for Any user > OK.
4-Go to the Actions tab and click New > In the Action dropdown, select Start a program > In the Program/script field, type: C:\Windows\System32\osk.exe > OK.
5-Save it and check to see if it works.
Please keep me posted.
