How to set the windows path in Windows 7

How to set the path in Windows 7. Goal: Setting the windows command path in Windows 7 Additional information: Modifying the path statement will enable an MS-DOS window opened in Microsoft Windows as well as older programs to locate files that may be required to run the program. In the old MS-DOS environment we used the PATH= command, located in the autoexec.bat file. Additional information about the MS-DOS path command that is still usable in Windows 2000 and Windows XP can be found on our path command page, additional information about the MS-DOS command can be found on our set command page. See our dictionary path definition for additional information about this term and related definitions. Answer: The path is now managed by Windows 7 and not the autoexec.bat or autoexec.nt files. To change the system environment variables, follow the below steps. From the desktop, right-click My Computer and click Properties. In the System Properties window, click on the Advanced tab. In the Advanced section, click the Environment Variables button. Finally, in the Environment Variables window (as shown below), highlight the Path variable in the Systems Variable section and click the Edit button. Add or modify the path lines with the paths you wish the computer to access. Each different directory is separated with a semicolon as shown below. C:\Program Files;C:\Winnt;C:\Winnt\System32

Do I have a 64-bit or 32-bit CPU (Processor)?

How to check what kind of processor you have (CPU) and what operating system can I run on it?

An X64 has a 64 bit microprocessor, whereas an X86, derived from the old 8086 PC, has a 32 bit microprocessor. A 32 bit machine and/or OS (operating system) is limited to about 3.55GB of memory, and an X64 is limited to about 17,179,869,184 gigabytes, 17,179,869 terabytes, or about 16 exabytes of RAM. Also a 32-bit OS cannot run an 64-bit OS.

So, how to check your CPU:

Since you cannot run WIndows7-64x on a 32-bit machine lets look at windows 7. From the Start icon on the toolbar select Control Panel. Look for Hardware and SOund and select View devices and printers. Double-click yur computer (will be labeled with your machine name). A Properties window pops-up with two tabs, select the Hardware tab. Look for a name starting with ACPI, with Type of Computer. If it says ACPI x64-based PC you know you have a 64-bit machine, CONGRATULATIONS! You can now install a 64-bit OS like Vista-64 or Windows7-64 and run any of your old software as the new 64-bit OS "knows" (is compatible) how to run the 32-bit apps.

What about memory?

If you want to install more than 4GB or RAM you will need to have a 64-bit CPU and also run a 64-bit OS otherwise you are wasting your money.
