I have discovered a way on Windows NT 4.0 to successfully watch YouTube and view modern websites for those who are so inclined to do so.

I have not yet tried this on Windows 95, but I will post back here and let you know of the results!

The following steps in order:

1) Install your copy of NT 4.0.

2) Download and install NT 4.0 Service Pack 3, the minimum service pack required for Internet Explorer 5.5 Service Pack 2 (SP3 released May 15, 1997).

3) Download and install Internet Explorer 5.5 Service Pack 2 Note, you will need to reboot after this, so save your work!.

4) Download and install Mozilla Firefox (the last version officially supported by Mozilla under NT 4.0) (Internet Explorer 5.5 Service Pack 2 contains files that are required to install and run Firefox; ironic, isn't it?)

5) Now download Flash Player 8. Do not install yet!

6) Now modify your registry in the following way from 4.0 to 5.0:


[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion]


(This change will fool Flash Player into thinking it is installing on Windows 2000 (NT 5.0 which is supposedly the minimum requirement for Flash 8, but I have determined it is not. Adobe only officially released Flash Player 7 as the final version for NT 4.0 but Flash 8 runs great!)

7) Now install Flash Player 8. Run Firefox, go to YouTube, and walah, you should have no problems watching videos on YouTube. Note, after installing Flash successfully, go back to your registry and change the value back to 4.0 from 5.0. If you don't you <u>may</u> experience problems installing and running programs that are specifically looking for NT 4.0, not 2000.

I tried Flash 9 and 10 with the registry change but it does not appear to work. So, as long as YouTube supports Flash 8, this hack will work. At least, until someone figures out another hack.

Again, I have not yet tried this on Windows 95, but I will post back here and let you know of the results!

Update1: This trick does not work with IE 5.5 and Flash 8 ActiveX, only Firefox and the Flash 8 plug-in. With IE 5.5 and Flash 8 ActiveX, you will receive a message on YouTube to upgrade your flash player.

Update2 12:57PM EST: Service Pack 6 High-Encryption 128-Bit for NT 4.0 is highly recommended for internet connection reliability, and while using multiple tabs in Firefox.

Update3 07:52PM EST: Unfortunately I am unable to test this on Windows 95, as it appears that my machine with 2.4GHz Pentium 4 can run NT 4.0 without a problem, but anything faster than 2.1GHz is too fast for Windows 95. See Microsoft's explanation here. A fix was never released for Windows 95 and 98 First Edition, and Microsoft had no plans of ever releasing one. I may be able to swap my processor out with one of my other Pentium 4 processors slower than 2.2GHz later tonight. I'll keep you posted.

Update4 02:23PM 06/11/2010: I have tried this on Windows 95 with another system, even with Firefox 2.0, and it does not seem to work. So it officially only works with NT 4.0.
