CMD into the Windows search bar, then right-click the command propt icon and select Run as administrator to open an elevated Windows command prompt.

fsutil dirty query [drive letter]:
This checks a given volume and returns an output indicating if the volume has it's dirty bit set. If so, the output will be output similar to the output below :
Volume - C: is Dirty

chkdsk /r [drive letter]
