Having to reinstall following Windows 10 upgrades

I like em-client and have used it for some time now. However, since installing Windows 10 I find that the whole account is “lost” and I have to reinstall the programme on each and every time Windows does one of its many minor upgrades. This is frustrating. In particular I have learnt that anything saved in local folders is not re-installed. Am I the only one with this problem ? Is there a solution? I have lost all confidence in the programme and may have to find an alternative
