Respect for intellectual property rights, everyone is responsible. Now we introduce the licensing method of Microsoft desktop products (ie Windows products); first introduce the several forms of Microsoft software products in the Chinese market:
1. COEM, OEM (random pre-installed products)< Br> Second, MOLP (open licensing products)
Third, FPP (color package products)
Fourth, ESD (electronic distribution version, for Windows8 after the listing of unique product forms)
the content of their respective products And features
First, random pre-installed products
For Windows random pre-installed products, there will be COEM (Certificate Original Equipment Manufactures) and OEM two forms, as the name suggests, random pre-installed products must follow the existence of the computer exists, Both products are bound to the computer motherboard and are not transferable. If the computer is damaged, the software product also disappears randomly. The advantages of these two products are that they are extremely inexpensive and can be downgraded, but only down to two levels, that is, Windows 7 can be downgraded to Windows XP, and Windows 8 can be downgraded to Windows Vista. The difference between OEM and COEM is that the OEM is pre-installed on the computer hard disk by the computer manufacturer. The customer can obtain the hardware product and cannot purchase it separately. The COEM product can be purchased separately, but the condition must be purchased with the new computer. If the purchase of a COEM product is installed on a computer that has already been used, although the software can be activated, from the perspective of authorization, this practice will be regarded as a wrong authorization, that is, the software is pirated.
Note: After purchasing these two products, please remember to protect the COA (Certificate of Authenticity) genuine certificate label
(COA genuine label)
2, MOLP (Microsoft Open License Pack)
This product form is Microsoft's largest sales volume. It is suitable for users who purchase a large number of Microsoft products, especially enterprise users. The minimum 5 sets are available. The main features are:
1, the product is permanent; Br> 2, its authorization is always authorized according to the product line, that is, to buy Windows products, now buy Windows 8, but you can downgrade to any version of Windows 8 before, such as Windows 7, Windows Vista, Windows XP , Windows 98, etc.,
3, can be transferred to use (except the Windows product line, this is not very good)
4, easy to manage, buy software products in this form, customers will be able to log in to Microsoft The Volume Licensing Service Center manages all the software purchased by the enterprise, including viewing authorization information, image downloading, key management, etc., avoiding the difficulty of managing the number of boxed products.
(Batch Licensing Service Center Interface)
5, MOLP includes a variety of purchase methods including GGS, EA, WEEA, Open, Select Plus, Open Value, etc., I want to explain here. GGS (Get GenuineSolution) is a purchase method. GGS is a software legalization solution launched by Microsoft according to the situation of a large number of Microsoft pirated software in China. This solution is only for the authorization of the Windows product line. For the price, Microsoft has one. The strategy of global pricing, but the price of GGS will be much lower than its standard price. And GGS is a full version of the license, and the purchase agreement such as EA is an upgraded version of the license, the purchase of the upgraded version of the license must first have a full version of the license.
Three, FPP (color package)
This product form is a boxed full version of the licensed product on the market, its boxed content is basically the same as COEM products, but the packaging is more beautiful. Its characteristics are that it can be used for transfer, but there is no permission to downgrade. However, the price of such products is relatively high, and personally feel that it is not very cost-effective;
4, ESD (ElectronicSoftware Download)
Because the COEM product line is not well managed, there are many market fakes, Win8 products cancel the COEM and FPP product lines ( So everyone can see all the Windows 8 boxed products in the market is absolutely fake), and because individual users will not buy products through MOLP, Microsoft has launched ESD products, that is, customers through the Microsoft official store Online purchase of software products, its characteristics are basically the same as FPP, can not be downgraded, can be transferred, but the difference is that ESD does not have CD media and packaging, and such software license belongs to the upgrade version of the authorization, and FPP belongs to the full version of the authorization, That is, FPP is legally installed and used on bare metal, and ESD is installed on bare metal for wrong authorization. Therefore, the purchase of ESD products must require the client computer to have the legal full version license of Win7 or XP.
