The Windows 10 Update and MetaTrader
As you may already be aware, on 11 April Microsoft released the Windows 10 Creators Update. This release is similar to installing a new operating system, because it will change configurations and encryption keys.
The MetaTrader platform binds all data to the local operating system and hardware in order to protect user information. This binding means that even if the terminal files are stolen, no one will be able to connect to the server using previously saved accounts.
Unfortunately, after the operating system change all passwords for trading accounts stored on your computer will become invalid.
Due to the change of encryption keys, one activation token for applications purchased from the MetaTrader Market will be lost, because all products are bound to the operating system.
Because of this, MetaQuotes has automatically added one activation token for each purchased product, regardless of the operating system it's used with. Traders can also re-download demo versions of products from the Market.
We apologise for any inconvenience that this may have caused. If you have any questions, please don't hesitate to contact our customer support team or your account manager.
