The little-known winstart.bat batch file

Raymond Chen explains what, exactly, the file winstart.bat in Windows 95 is used for.

In Windows 95, you could create a winstart.bat file in your Windows directory. During startup, the virtual machine manager initializes and creates the so-called “System virtual machine” (the “System VM”), which is the virtual machine that all Windows programs run in. But before running the user-mode kernel in that virtual machine, the virtual machine manager runs the winstart.bat batch file if it exists.

Chen needs to use several diagrams to really explain what the batch file is used for, but as a very crude summary, it allows you to load TSRs that only apply to Windows programs, while not affecting any additional DOS command prompts you may load later after Windows is already running. While many think it’s a Windows 95 feature, it was already present in Windows 3.x.

A unique feature that I doubt many people made active use of.
