NOTE: Actual Windows 95 disk space requirements will vary with individual system resources that Windows 95 must support using drivers and other system components.

Memory ..... 4 MB of RAM (minimum); 8 MB (recommended)
Video display ..... VGA (minimum); Super VGA (recommended)
Disk space ..... 30 MB of free hard-disk space is recommended. The full custom installation requires a minimum of 19MB. A certain amount of free disk space may also be required for a swap file, depending on how much RAM the computer has. As a guideline, 14 MB of memory is required, which can be divided between RAM and disk space.
For example: If the computer has 4 MB of RAM, at least 10 MB of free disk space is required for a swap file. If the computer has 14 MB of memory, it needs very little disk space for a swap file.
