Though IBM still had rights to HPFS, its agreement with Microsoft to continue licensing the HPFS386 version was contingent upon the company paying Microsoft a licensing fee for each copy sold. This was a result of the Microsoft and IBM collaboration that gave both the right to use Windows and OS/2 technology.

Due to the Microsoft dependence, limited partition size, file size limit of 2 GB and the long disk-check times after a crash, IBM ported the [[journaling file system]], [[JFS (file system)|JFS]], to OS/2 as a substitute.

[[DOS]] and [[Linux]] support HPFS via third-party drivers. [[Windows NT]] versions 3.51 and earlier had native support for HPFS.

[[Windows 95]] and its successors [[Windows 98]] and [[Windows Me]] canhave readno andsupport writefor HPFS only when mapped via a network share; they cannot read it from a local disk. {{citation needed span|date=May 2023|They listed the [[NTFS]] partitions of networked computers as "HPFS"}}, because NTFS and HPFS share the same [[Partition type|filesystem identification number]] in the partition table.

[[Windows NT 3.1]] and [[Windows NT 3.5|3.5]] have native read/write support for local disks and can even be installed onto an HPFS partition.
