It is believed that many inexperienced people do not know what to do to identify whether the computer pre-installed system is authentic Microsoft. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

At present, the brand machines sold by "computer City" (involving various brands, not to mention one by one) are mainly installed operating systems: Windows XP, Windows Vista and Windows 7 (mostly Windows XP and Win7). Brand machine dealers in order to reduce costs and expand sales, PC manufacturers of the "bare metal" or pre-installed Linux system, installed or modified tomato-like "forum version". This has formed a common strange phenomenon: the installation of "pirated"genuine" brand machines.

So, how to accurately identify the brand machine random system is the official genuine version or "forum version" or "modified version"?

Brand machine pre-installed official authentic features:

First, use "SLIC Tool Kit" (see: a prerequisite for activating Windows7 by browsing BIOS? SLIC Toolkit V3.0) tool to verify:

1. There are SLIC 2.0 or 2.1 corresponding to the brand in the motherboard BIOS.

2. The random system integrates the OEM certificate and OEM SLP Key corresponding to the brand. (note: Windows XP only has BIOS SLP 1.0 and OEM SLP Key).

Second, the second field of the random system "install ID" is "OEM", that is, XXXXX-OEM-XXXXXXX-XXXXX (right mouse button / computer or my computer / properties).

Have a brand identity in the computer or my computer properties. Connect to Microsoft genuine Verification Center: be able to pass the genuine verification smoothly.

Third, there is a random system "authentic logo" under the brand keyboard.

The body of the famous brand machine has an anti-counterfeiting bar code and a second key OEM COA Key (note: the key is "one-to-one"). OEM SLP Key has the same version versatility). After activating the system with this key, the second field of installing ID is also "OEM".

How to accurately identify the authenticity of the system:

At present, most of the tomato-like "forum version" installed in the "computer City" brand machine is the Windows XP GHOST system. The reason for using the "GHOST system" is mainly for distributors to save time, effort, simplicity and speed in order to install the operating system.

The second field of the "GHOST system" installation ID is generally "640", and most of the "my computer" properties have the words "forum logo" and "GHOST".

As for Windows Vista and Windows7, individual brand machines also install tomato-like "forum version" (distributors can still do the first and second items as long as they are willing to take the time and work hard to use the original Microsoft CD image + "hard brush" or "soft modification"). To identify whether Windows XP, Windows Vista and Windows 7 are genuine or unauthentic, it mainly depends on whether the brand machine has a random system "authentic logo", especially whether there is a security bar code and a second key OEM COA Key (that is, genuine certificate COA) on the back of the machine body. See below for the style.
