The two companies had significant differences in culture and vision. Microsoft programmers also became frustrated with IBM's bureaucracy and its use of lines of code to measure programmer productivity. The two products have significant differences in API. This was especially painful in providing support for DOS applications.

Given these issues, Microsoft started to work in parallel on a version of Windows which was more future-oriented and more portable. From a business perspective, it was logical to concentrate on a consumer line of operating systems based on DOS and Windows, and to prepare a new high-end system in such a way as to keep good compatibility with existing Windows applications.

It provided a bit API for native programs, though the OS itself still contained some bit code and drivers. This was a fully object-oriented interface that was a significant departure from the previous GUI. Rather than merely providing an environment for program windows such as the Program Manager , the Workplace Shell provided an environment in which the user could manage programs, files and devices by manipulating objects on the screen.

With the Workplace Shell, everything in the system is an "object" to be manipulated. A problem in DOS mode could crash the entire computer. This included an extensive set of configuration options to optimize the performance and capabilities given to each DOS program. Later, release 3. Compatibility with Windows 3. Multiple Windows applications run by default in a single Windows session — multitasking cooperatively and without memory protection — just as they would under native Windows 3.

However, to achieve true isolation between Windows 3. The user can then optionally place each program either in its own Windows session — with preemptive multitasking and full memory protection between sessions, though not within them — or allow some applications to run together cooperatively in a shared Windows session while isolating other applications in one or more separate Windows sessions. At the cost of additional hardware resources, this approach can protect each program in any given Windows session and each instance of Windows itself from every other program running in any separate Windows session though not from other programs running in the same Windows session.

A personal version of Lotus Notes was also included, with a number of template databases for contact management, brainstorming, and so forth.

As a result of the dispute, IBM signed the license agreement 15 minutes before Microsoft's Windows 95 launch event, which was later than their competitors and this badly hurt sales of IBM PCs. It also included major new architectural features including a system registry, JFS, support for UNIX graphics libraries, and a new driver model. A mission was formed to create prototypes of these machines and they were disclosed to several Corporate customers, all of whom raised issues with the idea of dropping Intel.

A partially functional pre-alpha version of Workplace OS was demonstrated at Comdex, where a bemused Bill Gates stopped by the booth. It was released in A project was launched internally by IBM to evaluate the looming competitive situation with Microsoft Windows That study, tightly classified as "Registered Confidential" and printed only in numbered copies, identified untenable weaknesses and failures across the board in the Personal Systems Division as well as across IBM as a whole.

The latest IBM version is 4. Version 1. After a series of preliminary "release candidates," version 2. IBM is still delivering defect support for a fee. Once application migration is completed, IBM recommends migration to a different operating system, suggesting Linux as an alternative. The additions are not provided with the current version of VirtualPC, but the version last included with a release may still be used with current releases. Thus, the Parallels, Inc.

Petitions were held in and , but IBM refused them, citing legal and technical reasons. Release dates refer to the US English editions unless otherwise noted.
