WinXP's setupp.ini - Unlock It

Unlocking WinXP's setupp.ini
============================


WinXP's setupp.ini controls how the CD acts. IE is it an OEM version or retail? First, find your setupp.ini file in the i386 directory on your WinXP CD. Open it up, it'll look something like this:

ExtraData=707A667567736F696F697911AE7E05
Pid=55034000

The Pid value is what we're interested in. What's there now looks like a standard default. There are special numbers that determine if it's a retail, oem, or volume license edition. First, we break down that number into two parts. The first five digits determines how the CD will behave, ie is it a retail CD that lets you clean install or upgrade, or an oem CD that only lets you perform a clean install? The last three digits determines what CD key it will accept. You are able to mix and match these values. For example you could make a WinXP CD that acted like a retail CD, yet accepted OEM keys.

Now, for the actual values. Remember the first and last values are interchangeable, but usually you'd keep them as a pair:

Retail = 51882 335
Volume License = 51883 270
OEM = 82503 OEM

So if you wanted a retail CD that took retail keys, the last line of your setupp.ini file would read:

Pid=51882335

And if you wanted a retail CD that took OEM keys, you'd use:

Pid=51882OEM

Create a Shortcut to Lock Your Computer

Leaving your computer in a hurry but you don?t want to log off? You can double-click a shortcut on your desktop to quickly lock the keyboard and display without using CTRL+ALT+DEL or a screen saver.

To create a shortcut on your desktop to lock your computer:

Right-click the desktop.Point to New, and then click Shortcut.
The Create Shortcut Wizard opens. In the text box, type the following:rundll32.exe user32.dll,LockWorkStation
Click Next.
Enter a name for the shortcut. You can call it "Lock Workstation" or choose any name you like.
Click Finish.
You can also change the shortcut's icon (my personal favorite is the padlock icon in shell32.dll).
To change the icon:
Right click the shortcut and then select Properties.Click the Shortcut tab, and then click the Change Icon button.
In the Look for icons in this file text box, type:Shell32.dll.
Click OK.
Select one of the icons from the list and then click OK
You could also give it a shortcut keystroke such CTRL+ALT+L. This would save you only one keystroke from the normal command, but it could be more convenient.

Click the Start button, and then click Search.In the Search Companion window, click All file types.
