The meaning of each version of Win 7

See a lot of people have doubts about the win7 version, collect and organize it, so that you can really understand the meaning of each version. By the way, the meaning of various software versions is included. I hope you have some understanding of the software version. Beta: It's easy to understand the beta, and the version at this stage will always add new features.

RC: (Release Candidate) Release Candidate is the release candidate. The biggest difference with the Beta is that the Beta will always add new features, but by the RC version, almost no new features will be added, but the main focus is on debugging!

RTM:(Release to Manufacture ) is a version of the factory that is heavily compressed, the content is the same as the official version, but RTM. also has a 120-day evaluation version. But it is wrong to say that RTM. is a beta. Is it necessary to take some time to compress, package and distribute before the retail store is put on the shelves? Therefore, the program code must be completed some time before the official release. The completed program code is called Final.Code. After the program code is developed, the master chip is sent to the factory for a large number of compression. This version is called RTM version. Therefore, the RTM version of the program code must be the same as the official version. However, it is different from the official version: for example, OEMs in the official version cannot upgrade and install. If the upgraded version is to be newly installed, it will check the old OS
CD, etc. These are the different places of RTM and the official version. But their main program code is the same.

Retail[full packaged product (fpp)]: The retail version is the kind of beautiful packaging that is seen in major software stores. You can upgrade the installation or you can install it completely. But it needs to be activated, and the machine configuration is changed. It is also a painful thing to notify Microsoft.

OEM: (Oringinal Equipment Manufacturer) is sold to computer manufacturers along with the computer, which is a random version. Can only be shipped from a random machine, not retail. It can only be installed freshly and cannot be upgraded from the old operating system. If you buy a laptop or brand computer, you will have a random version of the software. Packaging is not as beautiful as the retail version, usually with only one CD and manual (authorization).

upgrade: The upgraded version is the same as the retail version, but the price is much cheaper. You can only upgrade the installation. If you want to install it completely, the installation program will check the old operating system CD. After checking it, you can install it. It is estimated that this version will not be needed.

Volume licensing for organizations: group volume licenses (large purchase license contracts). Could someone think that this is not a vlo? In fact, vol is the first three letters of the volume, not the abbreviation of three words. For example, the vol version of the wxp pro cd version is wxpvol_en, where wx means windows xp, p is professional (vol has no home version), vol indicates a group volume license version, and en indicates English. The access is mainly for group purchases, which are also available to some msdn users. This version is further divided into the following five versions, such as the number of purchases, such as "open license", "selection license", "company agreement", "educational education license" and other five versions: System enthusiast club; open license; enterprise agreement; enterprise subion agreement; academic volume licensing. Volume licensing (product) keys, or vlk, refers to only one key, which is just a key used to prove the legalization of the product and installation, because the vol product does not need to be activated according to the vol plan. of! In other words, vlk does not refer to a version, but refers to the key required for this version during the deployment process, and the version of the key that needs vlk should be called vol! However, in practice, there is no need to emphasize the accuracy of this name and title. In addition, many people's vol version of the CD is obtained through the company's selective license, enterprise agreement, etc., so there will be many People call him "Select Edition" & so on.

-------------------------------------------- ------------------------------------ Attached: (detailed versions of various software)

α This version indicates that the software is only a preliminary product, usually only communicated internally by software developers, and a small number is released to professional testers. In general, this version of the software has more bugs, and it is better for ordinary users not to install it.

β(beta) This version has been greatly improved over the α version, eliminating serious errors, but there are still some bugs that need to be further eliminated by large-scale release testing. . This version is usually released free of charge by software companies and can be downloaded from the relevant site. Through the test of some professional enthusiasts, the results are fed back to the developers, and the developers will make targeted modifications. This version is also not suitable for general user installation.

γ This version is quite mature, and it is almost the same as the official version that will be released soon. If users can't wait, you can try it. Trial (trial version) trial software has been popular in recent years, mainly due to the rapid development of the Internet. This version of the software usually has a time limit. If the user wants to continue using it after the expiration, they usually have to pay a certain fee to register or purchase. Some trial software also imposes certain restrictions on functionality.

Unregistered (unregistered version) Unregistered version is very similar to the trial version, except that the unregistered version usually has no time limit, and the function is relatively limited compared to the official version, such as most VoIP software. The registered and unregistered versions have a large gap in call quality between the two. Some of them are the same as the official version in use, but they will pop up an annoying message box to remind you to register, such as the picture software acdsee, the intelligent Chenqiao Chinese character input software.

The demo version is also known as the demo version, which is the most popular in the informal version of the software. The demo version only integrates several features in the official version, quite a bit like unregistered. The difference is that the demo version generally cannot be changed to the official version by upgrading or registering.

The above are several versions before the official version of the software, α,β, γ can be called the beta version, there will always be multiple betas of mature software, such as windows 98 & beta; There are nearly 10 before and after. So many test versions on the one hand to meet the user's needs as much as possible for the final product, on the other hand, to minimize the bugs in the software. The trial, unregistered, and demo are sometimes collectively referred to as the demo version. The advertisements of this version are more intense, and it is quite a taste of the taste of the first purchase. For ordinary users, it is naturally free to try.

· official version (the official version of different types of software usually differs)

release this version means "final release" & rdquo; after a series of betas, There will be an official version at all, and for the user, buying the version of the software is absolutely not wrong. This version is sometimes referred to as the standard version. In general, release does not appear on the software cover as a word, but instead is the symbol (r), such as windows nt(r) 4.0, ms-dos(r) 6.22, and so on.

registered It is clear that this version is a registered version as opposed to unregistered. The registered version, release and the standard version described below are the official versions of the software, except that a large part of the predecessor of the registered version of the software is downloaded from the Internet.
