HoweverWhere do these variables and their values come from? How is the final value determined?
Factors that affect the final environment variables and their values
According to the MS document and other information on the Internet, I have summarized the possible impact of Windows XP.Final environment variableThere are five parts in total:

When Windows is just started, you often encounter failures such as "you can safely shut down the computer", shutdown immediately at startup, or restart at shutdown. The cause of this fault is caused by damage to the wininit.exe or Vmm32.vxd file. The solution is to retrieve the two files from the Windows installer package again. Or "Vmm32.vxd ". Click Start, and then follow the on-screen prompts to extract the file from the Windows CD-ROM or installation disk to the C:

. Trash-1000 (directory)
Note: Because I have installed Windows 7 and Ubuntu, files in windows can be accessed in Ubuntu. Therefore, files will be created on the corresponding disk. If Ubuntu is not installed, this folder does not exist.
The trash indicates that "junk" 1000 is the UID of your Ubuntu user.
This file is used to store files in the recycle bin. Similar to the $ recycl. Bin folder that Windows creat

BAT (batch file or batch program) File Syntax and skills
First, the batch processing file is a text file. Each line of the text file is a DOS command.
Second, the batch processing file is a simple program. You can use if and goto to control the process and for to execute a command cyclically.
Again: A compiled batch processing file is equivalent to a DoS external command, that is, as long as you store the BAT file
If the directory is set on the path, CMD can execute the BAT file at any location.
Token provides support for all types of programs in the system, including 32-bit and 16-bit! The correct 16-bit DOS command window is provided by command.exe. In WinXP, the file is located in the System Disk \ Windows \ hosts process to provide support for DOS Virtual machines (NT Virtual DOS Machine (NTVDM) under NT ). Therefore, we can say that Win × P has completely escaped the 16-bit DOS dependency. The so-called DOS program running environment on this system is just a completely virtual PC!
