Windows 10 oddities

I did a fresh install to Windows 10 this past week and have seen a few
strange behaviors that I've googled but didn't get any real advice so I
thought I'd ask the what I think are the smarted people on the planet :)

Before I did the upgrade I made a system image of my Win7 Pro and directed
it to my external USB drive. This external drive also maintains my weekly
My Documents backup.

I did the Win 10 install, and then copied my backup of My Documents data
from the external drive into My Documents on my C drive. So far so good.

But out of curiosity, on the external USB drive, I did a right click on the
win7 system image and selected properties just to see how big it was. I was
confused as it said 0KB. So I double clicked on the folder and was
presented with a message stating I didn't have access to that folder (even
though I am the admin and am using the same credentials used with Win 7).

So I right clicked again and selected sharing and was then allowed access
to the system image folder. However when I tried to drill into each folder
in the system image, I ran into the same message and had to share each
folder. Once I did that for all the sub folders I was then able to return
to the root drive and right click on the system image folder and could see
that it was 101gb.

So I'm perplexed as to why I didn't have access to a system image residing
in the same location as my documents, which I did have access to???

And second 'bug', today I installed my backup application (Karen's
Replicator) and then copied all my settings from my backup into the
application setting folder. When I ran the application my settings were not
there so I checked the folder where they are located (which I just copied
them to), and I right clicked on the settings.txt file and was presented
with a dialog that said 'file doesn't exist - would you like to create it'?
So I said yes, and then another dialog said I couldn't create the file
because it already exists???? WTH??? So I rebooted and tried again and the
same thing happened?

I'm scratching my head...

One of my buddies suggested maybe the ram is going bad, but I haven't
noticed anything out of the ordinary other than these two anomalies. So
tomorrow i will pull the ram and rub an eraser over it and re-seat them and
try again.

Comments anyone?

Anyone else having flaky stuff happen with Win 10?
