Как продлить работу пробной версии Vista/Server 2008 до 120 или 240 дней

Windows Vista and Windows Server 2008 has free activation grace period which allows user to install and use the operating system for 120 days and 240 days without product key or product activation completed. The initial grace period given is 30 days and 60 days respectively for Windows Vista and Server 2008, and user has to “rearm” the system when the expiration of grace period is nearly ending in order to reset and extend the trial evaluation period, and hence activation grace period again.

  1. Open an elevated privilege command prompt.
  2. Type the slmgr.vbs -rearm, and then press Enter to reset the activation grace period to 60 days.
  3. Restart the computer.

Neither Windows Vista nor Windows Server 2008 display prominently when is the activation-free evaluation grace period ends (even though it’s actively reminding user to activate Windows with information on how many days left to activate, which usually ignored by users). Surely you don’t want a warning dialog message box pops up suddenly to notify that you may be victim of counterfeiting or to activate the system now, especially if your notebook/laptop computer is used for business presentation. System administrators also certainly don’t want to face with uncertainty or instability possibly brought by expiry of activation grace period, especially if the server is running critical processes, applications or databases.

Instead of remembering the activation grace period expiry or ending date to manually rearm and reset activation grace period in Windows Vista and Windows Server 2008, Microsoft provides the following script which can be used with Task Scheduler to schedule automatic extension of the evaluation period and activation-bypass grace period of Windows Server 2008 every 60 days, which should be able to used in Windows Vista too which requires to be triggered every 30 days.

How to Automate the Rearm and Extension of the Activation Grace Period in Windows Server 2008 and Vista

  1. On the Windows Vista or Windows Server 2008 system, copy and paste the following Task code to text editor such as Notepad. In the Task, change the value of the following UserID tag (as in <UserId>domain\alias</UserId> line) to contain domain name and user name alias (for user on domain Active Directory), or local host name and user ID (for standalone Windows Vista user). Then save it as a .xml file. For example, ReArm.xml or Extend.xml.<?xml version="1.0" encoding="UTF-16"?>
    <Task version="1.2" xmlns="http://schemas.microsoft.com/windows/2004/02/mit/task">
    <Author>Microsoft Corporation (My Digital Life)</Author>
    <TimeTrigger id="18c4a453-d7aa-4647-916b-af0c3ea16a6b">
    <Principal id="Author">
    <Actions Context="Author">
  2. Click Start, point to Administrative Tools (in Windows Vista, go to Control Panel -> System and Maintenance), and then click Task Scheduler.
  3. In the Task Scheduler, click Import Task on the “Action” menu.
  4. Select the task .xml file saved from above above. For example, click Extend.xml or ReArm.xml.
  5. Click Import.
  6. A “Create Task” window will appear. Click the Triggers tab.Schedule Automatic Rearm Activation Grace Period
  7. Click the One Time trigger, and then click Edit.
  8. Change the start date of the task to a date just before the end of current evaluation period (activation grace period expiry date).User can also customize the schedule so that the Task Scheduler automates the rearm of system license status every 30 days (for Windows Vista) or 60 days (for Windows Server 2008) for 3 times. For example, change to Daily with recurring every 30 or 60 days, and then set an Expire date for the task after 120 days or 240 days.
  9. Click OK, and then exit the Task Scheduler.

The Task Scheduler will now run the evaluation reset and rearm operation on the date that been specified automatically to extend the free usage of Windows operating system.
