No. There is an update, which can only be installed on top of OSR2, called "usbsupp.exe." This update has been released to OEMs, and is also available in MSDN Professional Edition CD 1 dated November 1996. If you have OSR2 and want this update, contact the OEM you obtained OSR2 from (not me). If you do not have any USB devices on your system, this update will have no effect (and is easily uninstalled). This update will not install on any other version of Windows 95.
To see if USB 2.1 is installed on your system, go to Control Panel > Add/Remove Programs. "USB Supplement to OSR2" should be listed in the lower window.
For more info on USB (Universal Serial Bus), see Intel's USB pages.
Under the original release of Windows 95, I am able to dual-boot Windows 3.x and Windows 95 by pressing F4 on startup. Can I dual-boot OSR2 with Windows 3.x in this way?
No. Beginning with OSR2, no future release of Windows 95 will support dual-booting with Windows 3.x. You can still use a third-party boot manager (such as is bundled with Partition Magic 3.0, Windows NT 4.0, or OS/2) to dual boot. Simply editing MSDOS.SYS lets you boot to the previous OS but hangs when you try to boot to OSR2 again.
Jörg Weske has written a little app called Win95Boot as a workaround for this problem. I haven't tried it, so if you use it, please direct all comments to Jörg.
Waitaminute. I have installed OSR2, and I can still boot my previous operating system via F4 on startup. What gives?
Okay, here's the full story: When OSR2 was in beta testing, it had the ability, as do previous versions of Windows 95, to be installed as an upgrade, and to be dual-booted with a previous operating system. These features were removed when the final release version was made. However, a "non-crippled" version of OSR2 somehow leaked out, and is currently available from all your favorite pirate software sources. Thus, if you have a version of OSR2 that dual-boots with earlier operating systems, and that seamlessly upgraded your earlier version of Windows 95 (see below), then you are a software pirate.
The information in this FAQ relates to the final OEM release, and not necessarily to any "WAREZ" version of OSR2. There may be other differences between this and the release version of OSR2, but I do not know what they are, and do not want to know. Do not ask me how to obtain the "WAREZ" version or any other question about pirated software. Any such requests will be ignored.
What components of OSR2 are available for download, and what components are not?
Which large systems manufactuers are shipping systems with OSR2?
I'm not keeping up on such things, so check with the company before you buy. I hear that Dell and Gateway are shipping some systems with OSR2, though usually not with FAT32 enabled.
