Unluckily I’ve never used bazaar and it would take too much of the company’s time just to fix two typos.
The change proposal is to manually enable safeboot right after the registry changes, which reset each boot cycle by design, to avoid the failed boot (prior to the repair one) resetting them. Or at least that’s the working theory.
EDIT: Apparently reading further I ended up in this specific guide for my laptop model which does something similar (although not through command line but via the msconfig app)

Maybe the msconfig approach is easier on the user and to add to the RST guide.
