I was trying to manage my partitions, and it always used to work with, Windows Disk Management and with mini tool Partition Wizard and also with EasUS Partitions Manager.
Suddenly one day they all stopped working! Windows Disk Management would open, but would stay on the same message "loading Virtual Disk Service". Mini tool Partition Wizard would not open at all and EasUS Partitions Manager would display the error message "some programme has locked the services database. You must unlock it before you proceed".

How can I solve this?
