Folks, sorry for using an old thread (should I better create new one?), but I have question...

Could someone please recommend me a desktop wallet, which doesn't download the whole 100GB blockchain to your computer, but still provides the following features:
- allows backing up your private keys
- allows signing messages with your addresses
- has coin control features, so you could see and actually choose coin inputs for outgoing TX
Is there anything like that available for Windows?
I am using Electrum windows wallet which is very lite and you dont have to download the full blockchain. just install it and ready to use it, it gives you private key backup and all features you are requiring. Even it is very easy to take backup. It is just for you to take note of the passphrase key and where ever you want you can just download the software and restore the wallet through passphrase key and your wallet is ready.
