How to Crack Your Forgotten Windows Password.

Here at Xtremehow, we’ve covered many different ways to reset your password for Windows—but what if you can’t reset your password? Or what if you’re using drive encryption that would wipe out your files if you changed the password? It’s time to crack the password instead.

To accomplish this, we’ll use a tool called Ophcrack that can crack your password so you can login without having to change it.

Download Ophcrack

The first thing we will need to do is download the CD image from Ophcrack’s website. There are two options to download, XP or Vista, so make sure you grab the right one. The Vista download works with Windows Vista or Windows 7, and the only difference between XP and Vista is the “tables” Ophcrack uses to determine the password.

Once the .iso file is downloaded, burn it to a CD using the guide below.

If you are going to be cracking your password on something that doesn’t have a CD drive, such as a netbook, download the universal USB creator from PenDrive Linux (Link Below). A USB drive will not only run faster but you can also use a single USB drive for Windows XP, Vista, and 7 if you copy the needed tables to the drive.

To create a USB drive that works with all versions of Windows, download the free password tables from Ophcrack’s website.

Note: There are free tables available on Ophcrack’s website and there are paid tables, the paid tables will typically get the job done faster and will be able to crack more complex passwords but the paid tables may not fit on a USB drive because they range in size from 3 GB to 135 GB.

Now extract the tables to \tables\vista_free on the USB drive and they will be used automatically by Ophcrack.

Boot from CD/USB

Boot the computer from the CD or USB drive that you created.

Note: On some computers you may have to go into the BIOS settings to change the boot order or push a key to show the boot menu.

Once the disk is done booting, Ophcrack should start automatically and will begin cracking the passwords for all of the users on your computer.

Note: If the computer boots and you only have a blank screen or Ophcrack doesn’t start, try restarting the computer and selecting manual or low RAM options on the live CD boot menu.

If you have a complex password it will take a lot longer than simple passwords, and with the free tables your password may never be cracked. Once the crack is done you will see the password in plain text, write it down and reboot the machine to login. If your password isn’t cracked, you can also log in as one of the other users with admin rights and then change your password from within Windows.

With the free tables available you will not be able to crack every password, but the paid tables range from $100 to $1000 so you may be better off just resetting your password with on of these tutorials:

How To Recover Lost Data In Window 7?

We all know the importance of backups. If we’ve it heard once, we’ve heard it a million times. Always have backups, always save after every change, always use Dropbox (or something similar) to save previous versions – and everything will be alright. But accidents happen even to the most safety-conscious people. I, personally, saved things by mistake when I actually didn’t want to save changes. What then? What if you purposefully delete a file permanently only to realize it was actually not the file you meant to delete?
Fear not, Windows 7 has the answer. This guide will show you how to restore previous versions and recover deleted files using the Restore Previous Versions tool.

System Protection & Restore Points

In order for this method to work, you will have to enable System Protection. System Protection creates regular restore points every week, and also before major events such as driver  or program installations. If System Protection is disabled, restore points will not be created.
To check if it’s enabled, click Start, right-click My Computer and choose Properties. On the left side, click on System Protection. From here, you can choose your drive (you’ll have to enable it by drive) and click on Configure.

Here you can enable System Protection for all system settings and files, only for files and folders, or disable it entirely. You can also set how much disk space will be used to create restore points. The  more space you allocate for this the more restore points you’ll have, but your disk space will be used up, so use it wisely.

As I mentioned earlier, restore points are created automatically, but if you want to create one manually, you can do so at any time. In the System Protection tab, click on “Create”, name your restore point and create it. It might take a few minutes, but actually not as long as you’d expect.

Restoring Previous Versions

To restore a previous version of a file, right-click the file in question and go to the Previous Versions tab. Here you should find previous versions of your file. If you don’t see any, there might not have been a restore point since you created it, or your last modification was long ago and the restore point has already been deleted.

Before you restore a previous version, click open to see if this is truly the version you want. You can also copy the file to somewhere on your hard drive just in case. If you choose to restore, this will overwrite your existing version of the file.

If you also use Windows Backup, you will also be able to restore from backup at this point. You will have to have the media you used for backup available for that.

Restore Deleted Files

So this is the reason we all gathered here – let’s restore some deleted files.
To do this, you would have to access the previous versions of the folder in which your deleted file used to be. Go to that folder, right-click it and go to the Previous Versions tab.

From here, you can choose the version of the folder that you want and double click it. This will actually open a previous version of this folder, complete with all the files that were in it at the time.

From this folder you can simply copy or drag files to wherever you want. Just grab your deleted files and copy them back to where they’re supposed to go, and you’re done!
When I tried to do this, I got this security message:

But it’s OK, my own files weren’t really harmful and everything worked just fine!

Conclusion

The Windows 7 restore previous versions tool is actually extremely useful. I usually use Dropbox for this, but this is something I can use for every file and folder on my hard drive, and it only takes a few clicks to do so. The only downside is that you can’t really schedule restore points to happen whenever you want, so this is not really a solution that can replace backups. But for your everyday accidental deletion or change, it can be a real life saver.
