我在启动时运行此脚本以获取运行它的计算机的日期、时间和 Windows 版本：
ver >c:\Temp\TempVersionFile.txt
FOR /f "tokens=4 delims=] " %%a IN (c:\Temp\TempVersionFile.txt) DO set VAR=%%a
echo %COMPUTERNAME%;%DATE%;%TIME%;%VAR% >> \\mypath\myfile.txt
del c:\Temp\TempVersionFile.txt
exit
目标是避免在该计算机已注册的情况下再次注册数据，因此，每次启动时删除旧数据并用最新数据替换。
以下带注释的批处理文件可用于此任务：
@echo off
setlocal EnableExtensions DisableDelayedExpansion
set "DataFile=\\server\share\MyDataFile.txt"
set "VersionInfo="
rem The command line below for getting the version information works even for Windows XP.
for /F "tokens=2 delims=[]" %%G in ('ver') do for /F "tokens=2" %%H in ("%%G") do set "VersionInfo=%%H"
rem Do nothing if the command line above fails which is very unlikely.
if not defined VersionInfo goto EndBatch
rem Do not change the data file on containing already a line with
rem the name of this computer and identical version data. Date
rem and time are not updated in this case which should not matter.

rem move the filtered data file back to original storage location. If
rem that process fails because of the data file is opened currently by
rem another process which denies read and/or write access on the data file,
rem then exit processing of the batch file without updating the data file.
rem There will be one more chance in the near future to update the data file.

注1： 批处理文件可能同时被多台计算机运行，导致只有一个批处理文件可以读/写访问数据文件，而其他批处理文件则无法读/写数据文件。上面的批处理文件考虑了这一点，但并不是 100% 安全。最好用 C 或 C++ 编写一个 Windows 控制台应用程序，该应用程序处理共享文件访问拒绝，并等待一小段时间以使其他进程有时间完成，并使用带有计数器的循环来避免在无限循环中运行文件受到较长时间的读和/或写保护。
注 2： 计算机名称可以包含分号，如果数据文件应该是对此特殊也有效的 CSV 文件，则在将计算机名称写入数据文件时需要将计算机名称括在
