Windows wallet tutorial

Let's take Windows 10 as example. Other windows are similar.
Firstly please find the shortcut of Hydra. It's on the desktop or the start menu. Copy it to the desktop.
​
​
Right click on the short cut, click on Properties and click on Shortcut. Then add --salvagewallet to the end of Target.
Click on OK. The dialogue will be closed.
Now double click on the shortcut. The wallet will launch and reindex blocks.
We can have a look at the data menu of Hydra. Open menu %APPDATA%\Hydra. Please be careful and don't remove or change any content under this menu except you are aware of them.
Now the old wallet has been backed up to /wallets/wallet.1516172743.bak. The wallet is using the new wallet.dat file. It contains all private keys with brand new data.
After the above steps, it's better to remove the shortcut on the desktop in order not to reindex your wallet next time.
