Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

Full results can be found at:

This is one of the other random failures we get with advapi32:registry. 
The annoying part is that while here we get 9, other times it was either 
13 or 10 and whenever the value changes it looks like a new failure to 
the TestBot.

There are also several lines where it can happen so it combines to 
produce several different failure modes.

So if someone wants to look into it that will certainly avoid a bumch of 
false positives.
