Change Windows XP PID  

In XP if you have an OEM Keycode, you can not install XP from a non-OEM disk.

To fix this:

  1. Save the disk to a folder on your computer.
  2. Look for the SETUPP.INI file in the i386 directory.
  3. Edit the line with "Pid" to the appropriate PID (See Below).
  4. Save the edited folder back to a new disk. Making sure the volume label is rigth.

In the end the Pid line should look like:


For "Windows XP Pro OEM SP2"

With a Volume Label of:

Enable Multiple Concurrent Remote Desktop Connections on Winddows 7  

Download to your C:\ and 'Extract All'

Run %windir%\system32\msinfo32.exe to determine your systems build, etc...

Move to c:\Concurrent_RDP_Win7_7100_32_64 then edit the install.cmd file and
adjust 'WINVER', 'PRODUCTNAME' and 'CURRENTBUILD' to match the info from 'System Info', like shown:

SET WINVER=Windows 7 Build 7600
SET PRODUCTNAME="Windows 7 Professional"

Next, in an administrative command prompt move to c:\Concurrent_RDP_Win7_7100_32_64 and execute install.cmd as follows:

install.cmd -blank -multi

When it finnishes if you require blank password logins over the network (Which you really, really shouldn't do!!!)

Set 'Accounts: Limit local accounts use of blank passwords to console login only' to 'Disabled'

Install An Application When C:/ Isn't The System Drive.  

Some times you will run into an old application, or a poorly written new application, that expects your system drive to be 'c:/'.  This isn't normally an issue as most default installs have 'c:/' as the system drive, but...  As a technician I run into the odd oddball. 

Now, you could just change the drive letters, there is a good reg hack for that, and it's pretty straightforward, but...  There may be an easier way.

There is a command line program that will associate a path with a drive letter: subst

what you do is associate the root directory of your system drive to 'c:/', like so:

subst c: i:\

Then install the application.

There is one caveat. When the application asks you where you'd like to install the application, DON'T install it on the newly created 'c:/' drive.
