* {{anchor|c1}}Microsoft C 1.0, based on [[Lattice C]], was Microsoft's first C product in 1983. It was not [[The C Programming Language|K&R C]] compliant.
* C 2.0 added large model support, allowing up to 1MiB for both the Code Segment and Data Segment.<ref>{{Cite book |url=http://archive.org/details/Computer_Language_Issue_06_1985-02_CL_Publications_US |title=Computer Language - Issue 06 (1985-02)(CL Publications)(US) |date=February 1985}}</ref>
* C 3.0 was the first version developed inside Microsoft.<ref>{{cite magazine |last=Leibson |first=Steve |date=1985-02-01 |title=Software Reviews: Expert team analyzes 21 C compilers |url=https://archive.org/details/Computer_Language_Issue_06_1985-02_CL_Publications_US/page/n85/mode/2up?q=microsoft+c+3.0 |magazine=Computer Language |access-date=2020-06-05 }}</ref> This version intended compatibility with K&R and the later ANSI standard. It was being used inside Microsoft (for [[Microsoft Windows|Windows]] and [[Xenix]] development) in early 1984. It shipped as a product in 1985.
* C 4.0 added optimizations and [[CodeView]], a source-level debugger.
* C 5.0 added loop optimizations and [[x86 memory models#Memory models|huge memory model]] ([[Array data structure|arrays]] bigger than 64&nbsp;KB) support.
* C 5.1 released in 1988 allowed compiling programs for OS/2 1.x. The fourteen 5.25" disk (two of which were 1.2 MB, the others 360k) version included QuickC. The eleven 720k 3.5" disk version included with the OS/2 Software Development Kit included MASM 5.1 (a single executable that worked under both MSDOS and OS/2 1.x).
* C 6.0 released in 1989 added support for tiny memory model and better support for the ANSI C89 standard (the documentation explicitly says that it is not 100% compliant but it appears to be close enough for practical purposes). It added the ''Programmer's Workbench'' IDE, global flow analysis, a source browser, and a new debugger. To the surprise of many, C++ was not included even though competitors already had offerings.<ref>{{cite web | title = Optimizing With Microsoft C 6.0 | date = August 1, 1990 | url = http://www.drdobbs.com/windows/optimizing-with-microsoft-c-60/184408398 | first = Scott Robert | last = Ladd }}</ref>
* C/C++ 7.0 was released in 1992. Dropped OS/2 support.

** Standard: replaced QuickC for Windows.
** Professional: replaced C/C++ 7.0. Included the ability to build both DOS and Windows applications, an [[optimizing compiler]], a source [[profiling (computer programming)|profiler]], and the Windows 3.1 SDK.<ref name="IWreview"/> The [[Phar Lap (company)|Phar Lap]] 286 DOS Extender Lite was also included.<ref>{{cite news | title = Rival DOS Extenders debut at show | newspaper = InfoWorld | date = March 1, 1993 | page = 18 | url = https://books.google.com/books?id=fzwEAAAAMBAJ }}</ref>

** Visual C++ 1.52b is similar to 1.52, but does not include the Control Development Kit.
** Visual C++ 1.52c was a patched version of 1.5. It is the last, and arguably most popular, development platform for [[Microsoft Windows]] 3.x. It is available through [[Microsoft Developer Network]].
