    Huh? Those combined should take up under 400 MB.

  • yeah, a bug with windows/fdisk/other

  • I got this error:
    While initializing device IOS:
    Windows Protection Error. You need to restart your computer.

    So I'm using VirtualBox, and every time I start up the VM, it says, "FATAL: No bootable medium found! System halted." I have tried every single boot device possible and it still says that. I am using OSR 2 ISO (CD). Can someone help?

    Use a boot disk for any version of Windows.

    Your CPU is too fast. There are patches for this problem under the Windows 95 category here on WinWorld.

    can anyone help me with this error message: "While initializing device IOS:

    After a reboot it still gives the same error... only the options command prompt only/safe mode command prompt only

    Try using a patch hosted on WinWorld.

  • The German version here only comes with IE3.
  • IE 4 is present in the ISO and should be installed on first boot.

    Well, it did not install it. Is there a manual way do load it from the disc?
    Edit: never mind, it's in the win95 folder. No idea why it was not installed on my system though

    I can't find a working serial for Windows 95 & Microsoft Plus! Anyone has one that works?
  • @DPlex64
    There is a thread here that has various serials for various products. I'm pretty sure you'll find one here.

    For the Microsoft Plus! product key just use all 1s
  • Just so everyone knows you can upgrade from first release of windows 95 to 2.5 OSR OEM by Deleting WIN.COM and WINVER.EXE before upgrading!
  • Hey, someone knows how to install this on DOSBox?
  • Mouse does not work in vmware? any ideas?
  • Use PS/2 Mouse in VmWare, If it doesn't work use DOSbox Or PCem Or 86box
  • I love how the "Minimum free disk space" is 666MB.

    the min disk space is actually around 55-60 megabytes, also if your searching for a Valid OEM key but they all just dont work, you've came to the right place, here, i'll show to make a VALID oem key and how it'll always work when u make one using this method about to be listed.
    (valid cd key i tested using the method btw its for osr 2.5:24995-OEM-0700707-37345)
    ANYWAYS heres the method
    xxx95-OEM-0700707-37345: Make sure its from 001 to 366
    249xx-OEM-0700707-37345: It must be 95 or 96 or 97, NOT LOWER than 95 or over 02
    24995-OEM-xxxxxxx-37345: The first digit must be 0, The last digit MUST be 7 and the rest in that one can be either 7 or 0, Also You can use 9, 5 ,6 1, but they all need to be in it all at once or else it won't work. also you cant use more than one 9,5,6,1, Also 1 must be the ending sequence for this or else the 9,5,6,1 method for this one won't work.
    249xx-OEM-0700707-xxxxx: Any last digits you'd like.
    Now your CD Keys should always be valid!
    2nd example for osr 2.5 oem:14202-OEM-0770777-07548 (idk how its valid because its like about 4 months after end of life.+
    This method could also work with Other OSR OEM releases of windows 95 but idk since i haven't tested yet
    OSR 2 cd key for OEM: 33196-OEM-0569071-85340
    another TOO SIMPLE osr 2 cd key for OEM: 00100-OEM-0777777-77777
