Office Enterprise 2007 Key Microsoft Windows XP, a

As we all know,Office 2007 Ultimate Key, Windows XP SP2 adds a brand new security feature - DEP (Date Execution Prevention Information Execution Protection), you'll be able to safeguard your pc from viruses damage. In line with Microsoft's DEP technologies, Intel and AMD have developed a corresponding anti-virus CPU.


DEP

principle of anti-virus method in the event you upgrade to SP2, SP2's DEP characteristic enabled to avoid virus damage, mainly because the DEP to watch the a number of treatments to quit the virus within the protected memory place to operate damaging code. DEP through the processor's NX (No eXecute) characteristic, appear memory does not explicitly consists of executable code, data (these data are frequently the source code from the virus), obtain the information, NX them are marked as . If right after a plan in memory, attempting to implement these with So should you run a software program that has been subjected, DEP are going to be the virus code is marked as

In case you need to give complete play to DEP's protection, in addition to outside should certainly upgrade to SP2, your CPU should also assistance the DEP technologies. At present prevalent 32-bit processor (which include P4 Northwood, and so forth.) do not assistance NX, to support the technologies, the major CPU 64-bit AMD processor (Athlon 64, AMD Opteron), and Intel's Itanium CPU, J Sequence P4 Prescott, is said to nVIDIA, By way of, Transmeta along with other providers also plan to include the NX in its chip technology, however the speed of those businesses updates NX as well sluggish, consider a while prior to the official launch.

approach to enable or disable DEP

By default, SP2 important Windows plans and solutions only to allow the DEP. But you may also set up their very own, to ensure that all systems about the laptop or computer enabled DEP, to be able to prevent the virus. Additionally to Acrobat Reader5.0

instance,Office 2007 Activation, the make all of the plans and services are enabled DEP, strategy of operation is: Account login with administrator privileges SP2, after which click Double-click Enable DEP .

In case you need to a system (which include Acrobat Reader 5.0) to disable DEP, you are able to click on the above After the plan is incredibly vulnerable to attack, the virus can sneak into the system, and then spread to other systems about the computer and contacts in Outlook, and ruin your personal files. DEP is enabled, if any, immediately after the system cannot operate correctly, it is possible to acquire the application vendor DEP-compatible edition with the program, if no these types of edition is to disable DEP.


to support DEP, P4 Prescott

use of technologies in line with EDB Microsoft's DEP characteristic, Intel for their CPU developed technologies. At present Intel P4 Prescott (mPGA478 with LGA775 package) or for your C0 core stepping D0, the newest J Sequence P4 Prescott core with E0 stepping. Only J Series P4 Prescott with anti-virus function, only it genuinely assistance EDB technologies to satisfy the SP2's DEP antivirus characteristic that makes it possible for for buffer overflow (buffer overrun) Vulnerability in the design from the virus fall short to stop their replication and spread to other systems .

If you use a P4 Prescott / Celeron D (C0 stepping core) processors, upgraded to SP2, you may find a deadlock inside the Windows XP operating system, startup display, but do not place on P4 Northwood may have this challenge. This really is for the reason that SP2 can open P4 Prescott (C0 stepping core) includes the EDB capabilities, but this type of CPU and the execution just isn't EDB,Windows 7 Enterprise Key, EDB part of its internal energy transistor won't operate, and thus trigger the method to die lock.

To solve this trouble, Microsoft has launched in the September 14 amendment towards the related documents, we can go to Microsoft's official website to download. English version of Windows XP end users to download tackle is simplified Chinese edition of XP users to download handle

to assistance DEP, AMD 64-bit CPU using EVP strategies

AMD 64-bit processors the first to support Microsoft's DEP technologies. So that you can meet the DEP, AMD and Microsoft to style study and development of AMD's new chips characteristic AMD 64-bit processors (including the Athlon 64/Athlon 64 Fx / Athlon 64 mobile version / Sempron cellular edition,Windows 7 Activation Key, and so on.) may have the EVP. EVP and SP2's DEP feature technical cooperation, to avoid

However, AMD 64-bit processors within the machine after putting in SP2, as long as your computer starts, the DEP function, and configure the needed driver files named Mpegport.sys hardware, once you utilize the Sigma Design Enterprise Realmagic Hollywood As well as DVD decoder application will conflict with the DEP. This really is for the reason that older drivers are some comparable operation with the virus, so SP2 to error it for that virus, which set off the DEP, cause the personal computer to repeatedly restart. To resolve this challenge, Microsoft recommends that people update the older driver, or disable decoding software package for that DEP,Office Enterprise 2007 Key, flip off the SP2 virus protection.
