Where can I obtain a default V7 template?

with my V7 showing all templates with Model Space Scale 10, I need to be sure I am starting with an intended original 1:1 scale dimension style, as who knows what else has gotten changed different to intended.

Can I download from somewhere the original templates ?

6 months on from new PC and need to get started here…6 months of life gone… (estimate of 3 months way off)

Wish to open a default V7 template with all out of the box settings in it !
