PID: The process identifier number Windows has associated with the process. The process ID may be used by certain functions or system utilities. Windows assigns a unique process ID each time it starts a program, and the process ID is a way of distinguishing between several running processes if multiple instances of the same program are running. There are a few PID checkers, but none offer x64 support. Why i would like x64 is for use in WinPE x64. Lets say you get a laptop with a blank HD and wish to install the appropriate OEM version based upon the Bios key. I currently run Produkey from nirsoft wich gets me the key from bios and outputs it to a txt file.

When you buy Windows Keys from Microsoft websites or get them from the OEMs, you can be sure that they are genuine. Jul 01, 2011 I've bought a Vista key online, not from Microsoft. Other than testing it in the installation, is there a way online that I can test the code to see if its genuine? I'm going over to my friends place to install it with his Retail DVD and I don't want to look like an idiot if the key doesn't work. Windows Setup will use these files automatically during installation. Run Windows Setup. Setup uses these files during the Windows PE configuration pass as soon as it is launched. Note An answer file takes precedence over these files. If you use an answer file during installation, Windows Setup ignores the EI.cfg and PID.txt files.

Before you begin

Driver updates for Windows 10, along with many devices, such as network adapters, monitors, printers, and video cards, are automatically downloaded and installed through Windows Update. You probably already have the most recent drivers, but if you'd like to manually update or reinstall a driver, here's how:

Update the device driver

1. In the search box on the taskbar, enter device manager, then select Device Manager.

2. Select a category to see names of devices, then right-click (or press and hold) the one you’d like to update.

3. Select Search automatically for updated driver software.

4. Select Update Driver.

5. If Windows doesn't find a new driver, you can try looking for one on the device manufacturer's website and follow their instructions.

Reinstall the device driver

1. In the search box on the taskbar, enter device manager, then select Device Manager.

2. Right-click (or press and hold) the name of the device, and select Uninstall.

3. Restart your PC.

4. Windows will attempt to reinstall the driver.

If you frequently install Windows, here’s a trick to forestall version identification and license requests during the process. As documented in a TechNet article, you must out two files in Sources to make this happen. The first is named EI.cfg, and stands for “Edition ID.” The second is named PID.txt, and supplies the product key for Windows. My guess is that PID stands for something like “Product ID.” Together, EI.cfg and PID.txt install Windows license info automatically, without requiring user input during the install process.

How Do EI.cfg and PID.txt Install Windows License Info?

I’ll provide basic info here. But you can consult TechNet for the details. The article is entitled “Windows Setup Edition Configuration and Product ID Files (EI.cfg and PID.txt).” And though it’s labeled as “…archived and … not being maintained,” it still works fine for Windows 10. At least, as of Version 1607 (production) and Insider Preview 15031 as I write this post.

Creating EI.cfg

Notepad or any plain text editor is what you want for both of these files, which should go into the Sources directory on the installation media. Note: you can use the tool named UltraISO to deposit them directly inside an ISO file you may have built yourself or downloaded from MS. (Note: it costs $30 but is worth it, especially if you’re using a Volume License key which needs doing only once.)

The format of the EI.cfg file is as follows:

The stuff in square brackets you leave alone, the stuff in curly braces needs replacing. For {Edition ID} use the name of the edition you’re installing (Home, Pro, Enterprise, or Education). For {Channel} the value must either be “OEM” or “Retail”. Unless you’re an OEM, that means retail. If you’re using a volume license, the value for {Volume License} must be 1, otherwise 0 (zero). That’s it!

Creating PID.txt

If you thought the EI.cfg file was easy — and it is — PID.txt is simpler yet. It contains two lines. The first reads “[PID]” (omit the quotes, they’re just there to show you what to type. The second reads “Value=XXXXX-XXXXX-XXXXX-XXXXX-XXXXX” where you’ll substitute an actual and valid 25-character Windows key for the string of X’s. And that’s that!
