APPLIES TO


This article was previously published under Q148948

SYMPTOMS

When you run a batch file from a *.PIF file on a Windows NT computer, the environment variable "Windir" is not retained in the environment. Some applications make use of this variable, and it is normally available in the Windows NT environment. If it is not available, the application may fail.

RESOLUTION

At the beginning of the batch file, place an entry that reads:

SET windir=%systemroot%


This restores the variable to the environment.
