You can create a watch-only wallet to your WindowsPC for balance-viewing without opening your Tails wallet.
FYI, Electrum can create multiple wallet files.

It's like creating a copy of the whole wallet which can view the balance and transaction history (except the labels).
But by using the Master Public Key, you or a hacker won't be able to sign transactions using that "copy".

You can also restore the Tail Electrum's SEED to your WindowsPC if you failed to find a way to connect your wallet.
That's what I meant by "last resort" or no other choice.

BTW, what is the exact version number?
