[Grammar] On Windows or In Windows

[seco]

I'm writing Tech articles.
I have a simple question.
Which one is correct in Windows or on Windows?

Please give us a complete sentence to consider so we can give you a good answer.

Ask Which one is correct, "in Windows" or "on Windows"?

 

[Tdol]

I think it depends on the context. Both could be correct. Could you give us some examples?

 

[seco]

In Windows OS, you can install programs
I've installed it on Windows.

Are these sentences correct?

 

[GoesStation]

I'd write:

You can install programs on computers running the Windows operating system.
I've installed this program on a Windows PC or ​I've installed it under Windows.

 

[Tdol]

I suggest you use 'on' in both places.

In most cases I would use on, but I think in is fine in the first with that word order.
