MetaQuotes has released a hot fix update of the MetaTrader 5 terminal - build 1816 - to address the critical problem with compatibility between MT5 and the recent Windows 10 Update. Unfortunately, even if you update MT5 to build 1816, you will still have to enter login/password again and re-activate your MQL5 Market products in each terminal after you install the latest April Windows 10 update. Make sure you have your account numbers and passwords all written down somewhere before updating your operating system.
