Thank you for your continuous user support shveicar! What I am proposing is not something for DMD end users, but for the wallet developer.
It is possible to delay a Windows shutdown until the wallet has been shut down in a clean manner with the function I have posted.
Disabling operating system updates forever is not the best solution from a security perspective.
as the nature of DMD DIamond is technology agnostic
which means we will use the best technology that is able represent our coin rollout
fullfill our security and stability requirements
and increase cross blockchain interoperability
so dont expect that DMD Diamond wallet technology in 2 years is similar to now
maybe even much sooner there will be next technology leap
this corrupted blockchain at power outage is a limitation of actual codebase and will disapear once we make next evolution step
