  Hello all:  

   My w10, after the C: partition, there are 3-OEM-Partition.

   Can I delete these OEM partitions?  How?

The partitions you see I suspect are HP Recovery related . Safest way to remove the partitions will be using HP Recovery Manager in the Start Menu programs list. It will offer the opportunity to make a Recovery USB which is a back installation for Windows in case of drive failure/corruption. It will also offer to Remove the recovery partition. You can do both or either. To find HP Recovery Manager start typing it in the search bar/cortana bar beside your start button at left corner of taskbar.

    Hello CheryLG: 

    Thanks for your good reply.

    My PC had been clean installed last year. The OEM-partition I see now must not from HP company.

if you had a clean install done and removed the HP partitions I would imagine the only partitions you have now are those created by Windows 10 during installation. These are Win 10 System and Utility partitions. Neither should be very large at all and could present booting issues if deleted.
