Set an invisible password for Windows XP

        As the price of computer hardware continues to fall, the author's "master machine" has finally revived the glory through the upgrade, and also ran into a dual system (Windows XP and Windows 2000). Since the computer is placed in the dormitory, it naturally becomes a "public product", but there are many settings in the Windows 2000 system that really don't want others to see it. What should I do? Can't set a password! Thinking hard, finally I thought of a great method, the author will introduce it. (Click for more software tips.) First, find the boot information file (Boot.ini). Since it is hidden, we can select "Explorer" and select "Folder Options" in the "Tools" menu. Uncheck the "Hide protected system files" checkbox in the "View" option, and then check the "Show all files and folders" checkbox in "Hidden files and folders". This removes the hidden attribute, you can see the Boot.ini file in the C drive.
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)Windows
[Operating systems]
multi(0)disk (0)rdisk(0)partition(2)WINDOWS="Windows XP" /fastdetect
c:="Windows 2000"
The author will briefly explain that timeout=30 means that the selection menu appears at startup. The time, that is, the time taken to enter the default operating system when the user does not perform any operation after the system starts the boot menu. The default setting is 30 seconds, which can be changed casually. If it is changed to 0, then the selection menu will not appear and enter directly. The default system (here is Windows XP), if I don't want others to enter my Windows 2000 system, then modify this Boot.ini file to achieve. First set the timeout to 2 seconds, then delete the Windows 2000 after the last line of the equal sign. When starting up, others will only see Windows XP and one line. Windows 2000 actually has it, just can't see it. Who can think that at this time, just press the down cursor button to enter 2000? Because the waiting time is only set to just two seconds! In a blink of an eye, the system goes directly to Windows XP.
