'findstr' is not recognized as an internal or external command,

As others pointed, issue is in wrong settings of PATH variable in Windows. According to article this is most probably because some stupid installer wrongly modified PATH variable in Windows registry. Registry has 2 different string value types - REG_SZ and REG_EXPAND_SZ. Only the second one allows for expansion of %SystemRoot%.

So check your path by typing set path in command prompt. If you see unexpanded %SystemRoot% and other variables in Path, you are affected (PATH should show only plain directory names, not variables).

You need to edit Path variable in registry: HKEY_CURRENT_USER\Environment and HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment. As it is not possible to change the type of key, save the path value somewhere, delete the key and re-create it with type REG_EXPAND_SZ. You need to logout for changes to take effect.

Please go throught the simplest steps:-

1. go to C:\Windows\system32\ and copy findstr.exe file.
2. paste this file into the location C:\Program Files\Java\jdk1.6.0_24\bin
3. Run your jboss again you will get out of this.....

Please google it, you can find a lot of answers. But do as below to fix it. Add the following value to Right Click My Compuer -> Advanced -> Environment Variables -> System Variables -> Select Path variable -> append the below value.

C:\WINDOWS\system32

It should work with that change.

for me it works when I've coped findstr(from windows/system32) to wildfly/bin
