How to: set a password with Winrar

1. Open Winrar and browse to the files you want. If they're saved all over the place, it might be an idea to move them all to one folder, and compress that. Give the folder an informative name so you can easily identify it later.

2. Right click and choose Add files to archive. A new window will open.

3. The Winrar options for creating a new file can look a bit complex, but don't worry. You can modify lots of options, but you don't have to. Just make sure to choose where the new, locked file will be saved, and what it will be called.

4. Of course, the most important step is to apply the password. To do this, hit the Advanced tab > Set password. An Enter password dialog will appear - it needs to be secure, so pick a good one!

5. Once Winrar creates your locked RAR, it will look like any other. You can email, save, move and share it as normal, but when someone tries to open any of the files it contains, it will ask them for a password.

One thing to bear in mind - even though someone will need to enter a password before they can open the files, if they open the RAR with Winrar or an app like Peazip, they'll be able to see the file names without actually opening them. You might want to bear that in mind when you call that photo Crazyparty2012.jpg, ok?!

What is x84 or x64 ?

x86 or x64 and its probably too far above your head to understand in the first place. X64 bit systems use 64 bit processors, x86 use 32 bit processors. 64 bit processors are faster.
 x86 (32 bit) or x64 (64bit).. the difference is in their architecture 
the most easily noticeable difference is in the amount of ram usable, 
on windows 7 x86 has a max of 3.5gb 
x64 uses 4gb or more 
( some programs are x64 or x86 specific..)

x86 is the designation for the 32 bit version of Windows 7. The 64 bit version of Windows 7 is basically the same as the 32 bit version, but can address a far higher memory range natively. The 32 bit version of windows cannot theoretically directly access memory addresses higher than 4 Gigs. In reality, it is even less, since some motherboards reserve some memory for video (shared integrated RAM) and some other system resources. Most systems, even if you loaded it with 4 Gigs of ram, if you use x86/32 bit Windows 7, you will only see around 3.2 to 3.8 Gigs of RAM. So, in theory, using the 64 bit version is "better". In theory. 

However, in the real world, people that have to ask this question in the first place, are not likely to buy systems maxed out with 4 Gigs of RAM, and are not likely the type of power user that will need that full 4 Gigs of RAM. They just web surf or play a few games now and then. Those people will probably never put enough stress on their system to even start dipping into that 3rd Gig, let alone using over 4 Gigs. Also, not all applications are available in native 64 bit versions, and you end up running older 32 bit applications anyway. Even if you use an application that requires more ram, Windows already has a built in mechanism for providing more ram to the user, by swapping out pages of ram to a swap disk (the pagefile.sys). 

How to determine whether a computer is running a 32-bit version or 64-bit version of the Windows operating system

Use the following methods to determine which version of Windows is installed, as appropriate for the operating system that you are running. 

Windows 8

There are two methods that you can use to determine whether you are running a 32-bit or 64-bit version of Windows 8. If one method does not work, try the other method. 

Method 1: View the System window in Control Panel

1. Swipe in from the right edge of the screen, and then tap Search. Or, if you are using a mouse, point to the lower-right corner of the screen, and then click Search.
2. Type system in the search box, and then tap or click Settings.
3. Tap or click System.
4. If you are running a 64-bit version of Windows 8, 64-bit Operating System is displayed in the System type field under the System heading. If you are running a 32-bit version of Windows 8, 32-bit Operating System is displayed in the System type field under the System heading.

Method 2: View the System Information window

1. Swipe in from the right edge of the screen, and then tap Search. Or, if you are using a mouse, point to the lower-right corner of the screen, and then click Search.
2. In the search box, type system information.
3. Tap or click System, tap or click System Information, and then click System Summary.
4. If you are running a 64-bit version of Windows 8, x64-based PC is displayed in the System type field under theItem heading.
   If you are running a 32-bit version of Windows 8, x86-based PC is displayed in the System type field under theItem heading.  

If you cannot determine whether the computer is running a 32-bit or 64-bit version of Windows 8 by using these methods, go to the "Next Steps" section.

Windows Vista or Windows 7

If you have Windows Vista or Windows 7, there are two methods to determine whether you are running a 32-bit version or a 64-bit version. If one method does not work, try the other method.

Method 1: View the System window in Control Panel

1. Click Start
   
   , type system in the Start Search box, and then click system in the Programs list.
2. The operating system is displayed as follows:
   • For a 64-bit version operating system, 64-bit Operating System appears for the System type under System.
   • For a 32-bit version operating system, 32-bit Operating System appears for the System type under System.

Method 2: View the System Information window

1. Click Start
   
   , type system in the Start Search box, and then click System Information in the Programs list.
2. When System Summary is selected in the navigation pane, the operating system is displayed as follows:
   • For a 64-bit version operating system, x64-based PC appears for the System type under Item.
   • For a 32-bit version operating system, x86-based PC appears for the System type under Item.

If you cannot determine the operating system bit count by using these methods, go to the "Next Steps" section.

Notes

• To find the computer’s bit count, see the documentation that was included with the computer or contact the hardware manufacturer.
• Intel Itanium-based computers can run only 64-bit versions of Windows. Intel Itanium-based computers cannot run 32-bit versions of Windows. Currently, 64-bit versions of Windows run only on Itanium-based computers and on AMD64-based computers.
