Can't confirm it for W8.1, are you guys running the beta..!?
This isn't the beta on my win10 laptop but the latest regular release. I'm pretty much staying away from the betas now, I can do without the hassle.
If you look at my image again, the outdated ones are from November, so house cleaning has missed them, I was wondering if the same had happened to baudav.
I had thought to disable the self-defence module and remove these, but keep getting a file in use error for several files, even though these are old def sub-folders and with the shield control disabled. Looks like this will require action in safe mode or a reinstall.
