After a scenario like a system restore or failure, you may find it necessary to restore your wallet from a backup. Here is a simple guide on how to do this in Windows XP/Vista/7/8.

This process is going to be more or less the same for all coins, however there can always be exceptions that do not follow this format.

You can see a video walk through on youtube! CLICK HERE!

1) Download Client

Go and download the latest version of coin wallet for your coin you are looking to restore.

Dogecoin
Bitcoin
Litecoin
Potcoin
Mazacoin
Darkcoin

2) Sync Wallet

Install the client. I have installed the latest DogeCoin client for this demonstration.
Load the client and allow it to update the block index.
After it completes, completely exit your wallet client.

3) Replace Wallet.dat

Navigate to your clients storage location, and locate wallet.dat. Rename it to wallet.dat_old.

Windows Vista/7/8
C:\Users\ User Name \AppData\Roaming\ coin name

Windows XP
C:\Documents and Settings\ User Name \Application data\ coin name

Copy your backup wallet.dat into the folder.

4) Load Wallet

Load up your wallet and you are all set.

That should do it.

TL;DR
Start -> Run -> ” explorer %APPDATA%\<crypto coin> ” copy old wallet .dat into directory, replacing the current one
