Clean minimal install @ Win95a=26mb (maybe even less possible).
Clean minimal install @ Win95b=39mb (maybe even less possible).
Sorry to pick this up, but Wn95a or Win95b is possible @ 64mb. I used fdd version of Windows 95a or b and @ Win95b or OSR2 it is better to remove some unneeded junk from setup first to get more space, but without it, it was also possible. Without drvspace i did get Win95b + directx 6.1 to install, but no space was left for all dri vers. I used then drvspace3 compression that is available to install with Windows 95 plus and Win95b has it without windows 95 plus. Now i have Win95b +Directx7a + all drivers installed and still free space left. Games are installed to usb 2.0 stick or from network storage. I thin with compression it is maybe possible to install Win95a to a 32mb hdd with all drivers and older directx, 64mb has plenty storage space, i have hp t5300 and hp t5520.
Long story short, use compression to fit all needed stuff, mainly directx + all drivers. After compression 64mb hdd became ~119mb hard drive.
