A friend asked me a few days ago to help him write a batch file so that after his computer boots twice, it would ask whoever boots it for a password. So I wrote the following, but the result is that no matter how many times it boots, it always asks for the password :-) It made me look really bad! I took another look, and it seems like the order is wrong, but I still can't figure out how it should actually be written. Could one of you experts help this newbie out? Thanks in advance! @echo off echo k >1.txt if exist 2.txt goto over if exist 1.txt goto 1 goto end :1 ren 1.txt 2.txt ver c:\password :end exit

To sysjinglin: 　　The main problem is that there is no Goto end after the line ren 1.txt 2.txt; and the goto end above is somewhat redundant. 　　Also, this program still has problems in actual use. Asking for a password after being run twice is somewhat like a sharing restriction, but it is not suitable for use as a boot password, because the flaw that a batch file itself can be interrupted is quite serious, and the remedy is also rather troublesome. I suggest using it only for testing.
