China DOS Union

A couple of days ago, I wrote a simple piece of code to view the paths of programs that start automatically at boot . Regardless of whether the query is comprehensive or not, during testing, I encountered a very headache-inducing problem:

If the path of a program that starts automatically at boot contains N Chinese characters (the character type in the registry is REG_SZ, and other types of characters haven't been tested yet), then the last N characters of this path (one Chinese character occupies two character positions) will be ignored. It might be related to the fact that the internal code of Chinese is double-byte, and I can't specifically explain the reason. For example, create a REG_SZ string test under HKEY_Local_Machine\Software\Microsoft\Windows\CurrentVersion\Run with the value c:\program files\测试\test.exe. Then, after executing the code in , the line where test is located shows c:\program files\测试\test.e; if the above value is c:\program files\测试\再次测试.exe, the result will show c:\program files\测试\再次测.

How should this problem be solved?

1、 @echo off setlocal enabledelayedexpansion echo. echo The programs that start automatically at boot are: echo. for /f "skip=4 tokens=1* delims=:" %%i in ('reg query HKLM\Software\Microsoft\Windows\CurrentVersion\Run') do ( set str=%%i set var=%%j set "var=!var:"=!" if not "!var:~-1!"=="=" echo !str:~-1!:!var! ) pause>nul

Looking at the method of reading the registry at startup and processing the results by oneself is a bit thankless.

If it's the XP system, it is recommended to use WMIC to achieve it best: wmc startup, if you find the output result difficult to view, you can use wmic startup list brief, if you want to filter the output result, you can use wmic startup where filter conditions get output items.

One line of command can read multiple items of the registry, and there is no need to lay out by oneself, and no error handling is needed.

Regarding your code, I have doubts about the usage of tokens=1*. In addition, personally, I think the method of delims=: is not very good. The error in your result may still be due to the incompatibility of the character encoding scheme in the output of for and reg commands. You can redirect the result of the reg command to a text file, and then open it with a hex editor to have a look.

Create a project with a startup path containing Chinese characters.

reg query HKLM\Software\Microsoft\Windows\CurrentVersion\Run>aa.txt

Tried it, and indeed characters are being eaten.

Result:


! REG.EXE VERSION 3.0

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
wallpaper REG_SZ c:\windows\测试\壁纸自?
IMSCMig REG_SZ C:\PROGRA~1\COMMON~1\MICROS~1\IME\IMSC40A\IMSCMIG.EXE /Preload

Good question... Looking forward to the answer

The problem has been solved, and there are multiple methods:
One is to use the REG of 2003 to replace the REG of WINXP:

The second is that you can use VBS to return to CMD. I think this method is relatively good.
Set WshShell = Wscript.CreateObject("Wscript.Shell")
tt=WshShell.RegRead("HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\Start Menu") '' Read from value "Val"
Wscript.echo tt

I also have this situation. When querying, it shows normally, but when outputting to a file, it cuts corners.

D:\desktop>reg query "hkcu\software\microsoft\windows\currentversion\explorer\user shell folders" /v startup

! REG.EXE VERSION 3.0

HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\user shell folders
startup REG_EXPAND_SZ %USERPROFILE%\「开始」菜单\程序\启动
---------------------------------------------------------------------------------------------------------------
D:\desktop>reg query "hkcu\software\microsoft\windows\currentversion\explorer\user shell folders" /v startup >>test.txt
-----------------
Content of test.txt
-----------------

! REG.EXE VERSION 3.0

HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\user shell folders
startup REG_EXPAND_SZ %USERPROFILE%\「开始」菜单

Because this is a batch script for XP users, it's unrealistic to ask them to switch to 2003REG. I used the VBS method from floor 5, thanks.

Return VBS to CMD?
How to return, using file interaction?

Transfer from the very batch tireless:

@echo off
pause
for /f "skip=4 tokens=3 delims=此处为Tab键" %%a in ('reg query HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run') do (
(echo %%a
)
