Activation helps verify that your copy of Windows is genuine and hasn’t been used on more devices than the Microsoft Software License Terms allow. Checking your activation status. You'll first want to find out if your Windows 10 is activated and linked to your Microsoft account. Award-Winning Personal Productivity and Computer Training Software. 800-822-3522 Disc. Activation Key Issues- Sales & Customer Service. In one form, product activation refers to a method invented by Ric Richardson and patented (U.S. Patent 5,490,216) by Uniloc where a software application hashes hardware serial numbers and an ID number specific to the product's license (a product key) to generate a unique installation ID.

Product activation is a license validation procedure required by some proprietarycomputersoftware programs. 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 Ric Richardson and patented (U.S. Patent 5,490,216) by Uniloc where a software application hashes hardware serial numbers and an ID number specific to the product's license (a product key) 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 installations.

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 Internet. The application obtains the license limits that apply to that user's license, 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 encrypted files at an Internet terminal.

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. Andre, Ltd.


Microsoft Product Activation was introduced in the Brazilian version of Microsoft Office 97 Small Business Edition[1] and Microsoft Word 97 sold in the Hungarian market. It broadened that successful pilot with the release of Microsoft Publisher 98 in the Brazilian market.[1] Microsoft then rolled out product activation in its flagship Microsoft Office 2000 product. All retail copies sold in Australia, Brazil, China, France, and New Zealand, and some sold in Canada and the United States, required the user to activate the product via the Internet.[1][2] However, all copies of Office 2000 do not require activation after April 15, 2003.[3] After its success, the product activation system was extended worldwide and incorporated into Windows XP and Office XP and all subsequent versions of Windows and Office. 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.[4] This ruling was subsequently overturned in 2011.


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.)

If you put your computer to sleep manually or if it falls asleep automatically after a while, that means that your computer's CPU and some other components more or less turn off. If your computer is asleep, all of your running programs are effectively paused in a suspended state, and Steam will definitely not download games. You can't install it if your computer is off, but you can download them in the background while you play other games on Steam. Go to SteamSettingsDownloads and check Allow downloads during gameplay. Here are some pictures to guide you. I hope this helps you. Make sure 'Start a program' is selected and then click 'Browse' and navigate to the script you just made. Click on the 'Conditions' Tab and make sure 'Wake Computer to run this Task' is set. It is important to leave your computer on and not shut it down when you go to bed and want Steam to download while you are in dreamland with Xena. Steam how to download game while computer offline.

Some 'unactivated' products act as a time-limited trial 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 technical support 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.


  • It can enforce software license agreement 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.[5]
  • If the company ceases to support a specific product (or declares bankruptcy), 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.[5]
  • 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 EA to be using product activation to reduce second-hand sales of their games in order to increase sales of new copies.[5]
  • 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.

Launching ExtendSim 10

When ExtendSim is first installed, it launches in Trial mode*. Enjoy your trial for free for up to 30 days from the date you first run the software. Once you reach the end of that period – if you haven’t already purchased the product – then that free trial will end. Anytime during the trial or even after the trial has expired, you can choose to Activate ExtendSim to convert your trial to a Model Developer Edition Individual license of ExtendSim. (Note: Trial versions cannot be converted into Student, Analysis RunTime, or ASP versions.)

Each time you launch ExtendSim during the 30-day Trial period an Activation dialog appears with three options:

Try.* You'll have 30 days to access all the powerful simulation capabilities in ExtendSim. Until you purchase and activate ExtendSim, the Activation dialog will appear on startup and report the number of days remaining in your Trial period, plus there will be a 'Trial Version' watermark stamped behind all your models. But all that goes away on activation.

Purchase. Selecting this will take you to the online store to purchase an Activation Key for the Individual license. If you don't have an internet connection, ExtendSim will provide alternate methods for purchasing ExtendSim.

Activate. Make it official! Drop your Activation Key and other required information into the entry fields. Your ExtendSim license will automatically be activated and tied to the computer upon which the activation is long as you have an internet connection on that machine. If you don't have internet access, ExtendSim will offer alternatives for activating your license.

* There is no Try option or Trial mode for the Analysis RunTime (ART) or ExtendSim Student.
Trial versions do not run on virtual machines.

Activating ExtendSim 10

Activation is automatic once you enter your Activation Key in the Activation Dialog (unless your device doesn't have internet access or your system's security system blocks the activation). If you are unable to accomplish activation automatically, you can do it manually in-house (not applicable to the Student version of ExtendSim). Once activated, ExtendSim displays your Activation Key and date of Maintenance & Support Plan expiration on your ExtendSim startup screen.

Moving an Individual License of ExtendSim from One Device to Another

It’s important to revoke your license from your original device before trying to activate on a new device.

Make copies of your ExtendSim models, any custom blocks, etc.

Revoke the Activation Key. This removes the license from the previous device. Use the Help > Revoke License command (or the Help > Deactivate ExtendSim command if prior to ExtendSim 10.0.5).

Uninstall ExtendSim.

Use the Windows Settings > Apps and Features to uninstall ExtendSim 10.

Then delete the two folders: Documents/ExtendSim and Program Files/ExtendSim.

Install ExtendSim on the new device by downloading the appropriate Trial version.

Paste your model files, etc. from the previous device to the new installation of ExtendSim.

Launch ExtendSim on the new device and activate it using the same Activation Key you used for your initial installation. (If for some reason you weren’t able to deactivate ExtendSim on the previous device, you will get an error message stating your Activation Key is already in use on another device. In this case, contact Imagine That Inc.)
