    I updated from Windows 7 to Windows 10 and all went well for about 2-3 weeks.
    However the last few days I have gotten a few errors.

    Right no, when I try to delete a file or folder I am getting a dialog box with the title Action interrupted. The message given is Invalid MS-DOS function and the options to Try Again, Skip or Cancel

    Just wondering if anyone has comes across anything similar. I have tried various files on C: drive and also network locations.

    And yes, I did try switching it off an back on again
    thanks for reading
    :confused:

    I had a quick Google, and while it's a rare enough problem, there isn't a clear solution to it.

    First and probably easiest things to try are to optimise and defrag your hard drive. For most problems, this probably wouldn't help, but others have had success with it.

    Right click on your hard drive, then click properties => Tools => Optimise and defragment drive.

    Seen a similar issue to this when the file explorer window is still open, it won't allow the delete because it gets confused about the number of users, and if the file is open for write or not.

    In some cases, making sure all the other windows are closed, and then trying again will clear it, but in some cases, closing everything still does not allow the delete, there's some sort of timing issue with it, and after a time, the blocking lock is removed, and the delete then will work correctly.

    A reboot usually clears the locks, so the delete will work on restart.

    Shore, if it was easy, everybody would be doin it.😁

    For what it's worth, I find that I can delete pdf files but not jpeg or doc files.

    I followed recommendations from Microsoft community and couldn't get the computer to restart properly. Eventually I interrupted the startup ( with esc key) , did a backup, and finally the computer restarted correctly .

    Not too sure about this win 10. Anyone know if I can revert to Windows 7 and install windows 10 at a later stage or do you only get one free upgrade?

    I had this issue before and Logging into Safe mode and deleting the files sorted it for me.
