I want to know about any wallet for windows where security is the first priority and breaking in through Internet should be difficult. Paper wallets can be good for it or hardware wallet?
the security is not only provided by the wallet type you use, but security is actually gained mainly by the way YOU use such setups. for example paper wallets aren't secure on their own, you have to make a lot of effort to make them secure (offline air-gaped system, a good trusted tool to generate key, encryption, proper backups,...). this effort is less with hardware wallets but it still exists.
