You link to an article and describe your issue in a way that I'm pretty sure the root cause is Windows' fault. Vim certainly isn't setting directory permissions to read-only across your filesystem! But Vim settings might combine with this to lead to your problem writing files.

I think it's possible that if Vim creates a file in a directory, and the directory is read-only, that Vim will also create the file as read-only.

But depending on your settings, Vim might edit EXISTING files by first renaming the old version of the file, then writing a NEW file with the old name. If I'm right about how Vim creates new files in a read-only directory, then this would cause the file to be readonly.

So read the following help topics and check the value of the associated options, maybe you can find a fix here:

:help 'backupcopy'
:help 'backupskip'
:help 'writebackup'
