If your CPU does not have this feature, it will not be able to activate this protection feature. The next step is to configure Windows to allow it to match this feature Operating system configuration For operating systems, both Linux and Solaris have adopted this technology in the last few years, but for Windows operating systems, this technology is only available on Windows XP SP 2. So if you If you use Windows XP, you need to upgrade to SP2. You can check if SP2 is installed by clicking on the System icon in Control Panel. If your operating system is SP 2, it will be listed under 'System'. If not, you need to install SP2. In Windows XP SP2 and Windows Vista, you can check whether NX technology is enabled correctly by clicking the System icon in Control Panel. On the window that appears, click the Advanced tab, as shown in Figure 3.

In this window, click the first Settings button in the ' Performance ' field. The Data Execution Prevention tab will appear on the window that appears. This is where NX technology is configured or not.

Figure 4: Configuring NX technology

As you can see, there are two options: ' Turn on DEP for essential Windows programs and services only ' ( Turn on DEP for necessary Windows programs and services ) and ' Turn on DEP for all programs and services except those I select '( Turn on DEP for all programs and services except the ones you choose ). This means that this technology will only protect the necessary Windows programs and services. With this configuration, NX technology will not protect you against viruses or Trojan Horse if they attack with a certain program. Therefore, we recommend using the second option, which will work for all programs and services. If in the future you make a mistake - for example, Windows warns that a program that you know is not infected is trying to execute the code in the mapped memory location as the data area. then you can simply enter this window and add that this is a good program in its exclusion list, done by clicking the Add button. Click OK , restart the computer, then your computer is protected with NX technology. However, as we said, although with this technology, you still have to use an antivirus program and remember to regularly upgrade the program. This is just a feature added to the extended security layer for computers.
