Bypass Vista Activation

While running a copy of Windows Vista that hasn't yet been activated, click the Start button, type regedit into the Search box, then press Enter to launch the Registry Editor.

Explore down to the following Registry key:

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ SL

Right-click the Registry key named SkipRearm and click Edit. The default is a Dword (a double word or 4 bytes) with a hex value of 00000000. Change this value to any positive integer, such as 00000001, save the change, and close the Registry Editor.

Start a command prompt with administrative rights. The fastest way to do this is to click the Start button, enter cmd in the Search box, then press Ctrl+Shift+Enter. If you're asked for a network username and password, provide the ones that log you into your domain. You may be asked to approve a User Account Control prompt and to provide an administrator password.

Type one of the following two commands and press Enter:

slmgr -rearm
rundll32 slc.dll,SLReArmWindows

Either command uses Vista's built-in Software Licensing Manager (SLMGR) to push the activation deadline out to 30 days after the command is run. Changing SkipRearm from 0 to 1 allows SLMGR to do this an indefinite number of times. Running either command initializes the value of SkipRearm back to 0.

Reboot the PC to make the postponement take effect. (After you log in, if you like, you can open a command prompt and run the command slmgr -xpr to see Vista's new expiration date and time.

The Base score value in Windows Experience Index displays the minimum value for the five components that Windows Vista tests to determine the Windows Vista Experience Index. Therefore, the Base score value represents the value of the lowest sub-score when Windows Vista tests the components in the computer. Windows Vista tests the following five components:• Processor
• Memory (RAM)
• Graphics
• Gaming graphics
• Primary hard disk
Consider the following example.

The following displays results from Windows Vista Experience Index:
Component /What is rated /Sub-score.

1.Processor Calculations per second 4.8

2.Memory (RAM) Memory operations per second 4.9

3.Graphics Desktop performance for Windows Aero 5.0

4.Gaming graphics 3D business and gaming graphics performance 4.9

5.Primary hard disk Disk data transfer rate 4.5

In this example, Windows Vista sets the Base score value as 4.5 because the lowest value for these tests is 4.5.
