Hi All, am new here. I live in France my language is English. Earlier this year purchased A H.P all in one desktop touch screen. I thought at the time it was the model with multi language but it turns out it was a single language model. I didn't send it back through one thing or another. To remedie this I purchased from Microsoft a windows 8.1 OS and downloaded electronically in , this allowed me to change the language. I now want to upgrade to windows 10 but it will only allow it in the computers original language and if I do this I will loose all my apps and software , backing up is not problem for documents etc.
Does any one know if there is a solution to this problem?

Thank you. Richard
