Data execution protection can provide data confidentiality for the majority of users, so that the data will not be easily disclosed. However, the data execution protection function still has many defects, the most important point is that it will affect the normal use of some programs of the user, at this time, data execution protection will have to be turned off. There are two ways to turn off data execution protection, which are described in detail in this article.

Method 1:

Turn off data execution protection, edit the Boot.ini file, and change / NoExecute=OptIn to / NoExecute=AlwaysOff.

To edit Boot.ini, right-click on my computer in the beginning-Properties-Advanced, Startup and recovery Settings

Method 2:

Win XP SP2 has a data execution protection function, which needs to be used with processors that support data execution protection functions, such as AMD Athlon64 and Intel Pentium4 processors with the letter "J" in their numbers.

The data execution protection function can effectively prevent unauthorized programs from accessing the protected memory area. Once such memory access occurs, the program will be forcibly closed by Windows, so as to protect the security of the system.

However, for early applications, there may be compatibility problems with data execution protection functions, resulting in problems such as application failure or system panic. If you want to continue to use the application normally at this time, you can turn off the data execution protection function. The method of operation is as follows:

Open the BOOT.INI file in the root directory of the system partition and edit it. Change the "/ noexecute=optin" to "/ execute", restart the system after saving, and then turn off data protection.

For example, the Boot.ini file contains the following:

The code is as follows:

[boot loader]

Timeout=30

Default=multi (0) disk (0) rdisk (0) partition (1) WINDOWS

[operating systems]

Multi (0) disk (0) rdisk (0) partition (1) WINDOWS= "Microsoft Windows XP Home Edition" / noexecute=optin / fastdetect

After modification, the last line changes to: multi (0) disk (0) rdisk (0) partition (1) WINDOWS= "Microsoft Windows XP Home Edition" / execute / fastdetect

After testing, the following will be fine.

Multi (0) disk (0) rdisk (0) partition (1)\ WINDOWS= "Windows Server 2003, Standard" / noexecute=optout / fastdetect

You can also use system Properties in the Control Panel to add the program as an example. To do this, follow these steps: 1. Click start, click run, type sysdm.cpl, and then click OK.

two。 Click the Advanced tab, and click Settings under performance.
