Activation

Brian Freeman found a flaw in my article. I told readers that “when it comes time to activate Windows, use the activation number on your PC.” But Microsoft no longer requires vendors to make this number readily available. Every legal copy of Windows has its own activation key, also called a product key or a product identification (PID). It’s made up of five groups of five characters each, and it’s unique to your copy of Windows.

Basically, it’s a proof of purchase. You can download and install Windows for free, but without a unique activation key issued by Microsoft and not in use on another computer, it won’t work for long. Email your tech questions to. When you install Windows, you’ll be asked to type in this key. If you bought Windows by itself, the key is in the packaging. If your PC came pre-installed with Windows 7 or an earlier version, the key is printed on a metal plate on the back or bottom of the computer.

But that's not the case if your PC came with Windows 8 or 8.1. Microsoft no longer requires manufacturers to put this key on your computer, and the manufacturers as a rule don’t do it. So what can you do if you need to reinstall Windows 8? You could send your PC back to the manufacturer and pay them to reinstall.

Or you could buy another copy of Windows-effectively paying twice for one product. Or you can take some precautions beforehand. If your PC is still running, you can get the activation key from Windows itself. The apply-titled program does this job quickly and easily. The program is free and portable; you don’t have to install it. You do need to download the right or version. ProduKey You can also get this key from, a free (but not portable) program that offers all sorts of useful information.

Once you’ve got the key, put it somewhere safe. Freeman suggests taping it to the outside of the PC. One more suggestion: When your PC is set up the way you want it, create an image backup on an external hard drive. This provides you with a quicker and easier way to restore Windows. You won’t need the activation key, and the restored version will have your programs and settings.

Windows 7 and 8 both come with image backup programs, but I prefer the more versatile.

Product activation prevents unlimited free use of copied or replicated software. Unactivated software refuses to fully function until it determines whether it is authorized to fully function. Activation allows the software to stop blocking its use.

An activation can last 'forever', or it can have a time limit, requiring a renewal or re-activation for continued use. In one form, product activation refers to a method invented by and patented ( ) by where a software application hardware serial numbers and an ID number specific to the product's license (a ) to generate a unique installation ID. This installation ID is sent to the manufacturer to verify the authenticity of the product key and to ensure that the product key is not being used for multiple. Alternatively, the software vendor sends the user a unique product serial number. When the user installs the application it requests that the user enter their product serial number, and checks it with the vendor's systems over the.

The application obtains the license limits that apply to that user's, such as a time limit or enabling of product features, from the vendor's system and optionally also locks the license to the user's system. Once activated the license continues working on the user's machine with no further communication required with the vendor's systems. Some activation systems also support activation on user systems without Internet connections; a common approach is to exchange files at an Internet terminal.

Was introduced in the Brazilian version of Small Business Edition and sold in the market. It broadened that successful pilot with the release of in the Brazilian market.

Microsoft then rolled out product activation in its flagship product. All retail copies sold in, and, and some sold in and the, required the user to activate the product via the Internet. However, all copies of Office 2000 do not require activation after April 15, 2003. After its success, the product activation system was extended worldwide and incorporated into and and all subsequent versions of and. Despite independently developing its own technology, in April 2009 a jury found Microsoft to have willfully infringed Uniloc's patent. However, in September 2009, US District Judge William Smith 'vacated' the jury's verdict and ruled in favour of Microsoft. This ruling was subsequently overturned in 2011.

An early example of product activation was in the MS-DOS program D'Bridge Email System written by Chris Irwin, a commercial network system for BBS users and Fidonet. The program generated a unique serial number which then called the author's BBS via a dialup modem connection. Upon connection, the serial number was validated. A unique 'key' was returned which allowed the program to continue for a trial period. If two D'Bridge systems communicated using the same key, the software deliberately crashed. The software has long since had the entire activation system removed and is now freeware by Nick J.

Contents. Blocking Software that has been installed but not activated does not perform its full functions, and/or imposes limits on file size or session time. Some software allows full functionality for a limited 'trial' time before requiring activation. Unactivated software typically reminds the user to activate, at program startup or at intervals, and when the imposed size or time limits are reached. (Some unactivated software has taken disruptive actions such as crashing or vandalism, but this is rare.) Some 'unactivated' products act as a until a product key—a number encoded as a sequence of alphanumeric characters—is purchased and used to activate the software. Some products allow licenses to be transferred from one machine to another using online tools, without having to call to deactivate the copy on the old machine before reactivating it on the new machine. Software verifies activation every time it starts up, and sometimes while it is running.

Some software even 'phones home', checking a central database (across the Internet or other means) to check whether the specific activation has been revoked. Some software might stop working or reduce functionality if it cannot connect to the central database. Criticisms.

It can enforce restrictions that may be legally invalid. For example, a company may refuse to reactivate software on an upgraded or new PC, even if the user may have a legal right to use the product under such circumstances. If the company ceases to support a specific product (or declares ), its purchased product may become unusable or incapable of being (re)installed unless an activation-free copy or final patch that removes or bypasses activation is released. Product activation where there is no straightforward way to transfer the license to another person to activate on their computer has been widely criticised as making second-hand sales of products, particularly games, very difficult. Some suspect companies such as to be using product activation to reduce second-hand sales of their games in order to increase sales of new copies. As the transfer of an activation request usually happens encrypted or at least obfuscated, the user cannot see or check if additional data from his/her machine gets transferred, creating privacy concerns. Malfunction of the activating mechanism can delay users from getting started using newly-licensed software.

Malfunction of the verification mechanism can cause vital software to suddenly stop working until re-activated or patched. This can happen in response to detected changes of installed hardware, other software, of the operating system. See also. References.
