Compare Standard 7 32-bit and 64-bit (Standard 7 SP1)
7/8/2014
The release of Windows Embedded Standard 7 gives you the ability to create images based on either the 32-bit or 64-bit versions of Windows 7.
To install the 64-bit version of Standard 7 on your device, your device must have a CPU that's capable of running a 64-bit OS. If your device is not capable of running a 64-bit OS, you must install the 32-bit version.
If your device can handle a 64-bit OS, then you can install either the 32-bit version or the 64-bit version of Standard 7. You may want to install the 64-bit version if your device has large amounts of RAM (typically greater than 4 GB), or if your device must run 64-bit applications. Since the 32-bit version of Standard 7 takes less space on your hard drive, you may prefer to install the 32-bit version if your device has limited memory or hard drive space.
