How would you start installation of Windows NT from Windows 3.1x and from Windows 9x?

My windows is windows XP, and any windows can work on any old software for older systems like windows 98

But in previous days error message say that I need windows 95 to be able to run the program so please anyone tell me what to do and how to stop this message. 

Error message:

This program requires Windows 95.

I have my windows 95 desktop folder windows set for 'no toolbar' and 'large icons'. However when i open a folder the toolbar is always present and the icons tend to be small. Every time i change the settings to the above it keeps reverting back to the opposite. Thank you for your help, much appreciated

 My system is installed with Windows 95 operating system. Does it  Support Internet Connection Sharing?

My computer broke down and I am left with this very old desktop computer, so I have no choice but to use it because I badly need to finish my project. When I tried to connect my computer to the router, it said that there is no connection.

It said something about an IP error. How can I check that? Is there supposed to be an IP address already?

Hay,

 I am having a technical issue which has not been solved yet. If anyone has knowledge about Win 95 Drive Space? Then the particular person probably can fix the issue. As much as I know about Win 95 Drive Space is that it was compression software which was available in Windows 95.

Well, the issue faced by me is that I have almost 50 back-up(old)  floppy disks of my father which all appear to be compressed with this software and the  problem is that I am not been able to open or look  them for the purpose of seeing, copying, moving or to save the files on the disk now. Whenever, I try to do so a particular message appears which am I need to run Drive Space via command line to decompress the files for viewing.

How do you remove the logon dialog in windows? Hope someone answers quick.

Thanks.

In Windows XP how do I create a password recovery disk just in case of forgotten password? I just want to be safe on this before something may happen.
