EDIT: i did as you said and I installed the mycelium application. By some chance, it has found the wallet :/

it was pocket change wallet.. so never bothered for a physical back up .... partly my fault then.

Microsfot NEVER NEVER DID THAT TO ME.

Imagine you install a Windows update and you find applications and application data DELETED. WTFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFf ARRRRRRRRRRRRRGHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH. I HATE GOOGLE.

I lost nearly all my bloody applications. 6 months of installations and search.
