环境变量多长的终极解决办法

环境变量太长解决终极办法：
新建一个环境变量path1，
将path的长串字符串复制出来作为path1的值；
然后将path的值全删，然后保留默认的值：
%SystemRoot%system32;%SystemRoot%;%SystemRoot%System32Wbem;
（本人保留了WindowsPowerShell）
%SystemRoot%system32;%SystemRoot%;%SystemRoot%System32Wbem;%SYSTEMROOT%System32WindowsPowerShellv1.0;
然后在path中加入path1：%path1%
重启cmd即可
