<P> Early multitasking systems used applications that voluntarily ceded time to one another . This approach , which was eventually supported by many computer operating systems , is known today as cooperative multitasking . Although it is now rarely used in larger systems except for specific applications such as CICS or the JES2 subsystem , cooperative multitasking was once the scheduling scheme employed by Microsoft Windows ( prior to Windows 95 and Windows NT ) and Classic Mac OS ( prior to Mac OS X ) in order to enable multiple applications to be run simultaneously . Windows 9x also used cooperative multitasking , but only for 16 - bit legacy applications , much the same way as pre-Leopard PowerPC versions of Mac OS X used it for Classic applications . The network operating system NetWare used cooperative multitasking up to NetWare 6.5 . Cooperative multitasking is still used today on RISC OS systems . </P>
