it is best to avoid windows 10 right now, but i don't think this is the case, of the first hacking attempt from microsoft, so it most likely that you were infected

you visited a shady website or probably downloaded something malicious, in other words it's your fault

What about the passwords?
I've never entered them on Windows 10

You had quite a considerable amount. Have you ever revealed how many bitcoins you have publicly, on any forum for example? This would make you a much easier target. Hackers would be able to target you by your IP address.

The truth of the matter is that these Bitcoin targeting malwares are and will be more and more numerous in the future.

As long as you don't port forward everything, there is no risk of you getting attack by your IP address. Vulnerabilities may be possible but I haven't heard of any for Windows that is this critical.

rootkit maybe? your system was already infected long time ago, and the hacker waited for a big amount? it is certainly possible

Certainly what I'm thinking too. The hacker might have gained control of the private key and run checks every x minutes to transfer the Bitcoins.

Was your wallet encrypted? Someone found your private key, this is the only way to make transactions on the blockchain. guessing a bitcoin private key is impossible. The question is how the attacker found the key. I think the computer has a rookit or trojan.

They have stolen bitcoins from my official Bitcoin wallet.
Wallet had the password (about 30 characters)
Last time I've entered the password at least 6 months ago.

Time to read the topic.

I've made clean installation of Windows 2-3 times since I've entered the passwords last time.
I hope the investigation of this case can improve the Bitcoin world and can prevent such incidents in future
