I have SAPI voices installed on my windows 10 machine as well as Windows 10 core voices and code factory voices. I am not using a SAPI voice but occasionally when I start up my machine SAPI 5 will take ove and say 'please register this product' when I type any key. I usually have to get sighted assistance to navigate back to the NVDA menu and switch to another voice.
Has anyone else had this happen? MOre importantly, how can I uninstall SAPI 5 voices altogether? I had a microsoft specialist remotely log in to my machine and he was not able to advise me as to how to do this.
I would say this problem happens about every three months.
