Hello,
After running Disk Doctor, as there were some problems on C:, it asked for a reboot to fix it.
After the reboot DD asked again for a reboot.
I did it once, and it asked again.
I could check in the Windows logs that everything was fixed after the first reboot (it is after all a chkdsk that is performed).
Therefore I suspect a little bug in this new plugin...
(I also tried relaunching the analysis, but the warning did not go away.)
