Have been having numerous minor problems with Win95 system and decided to reinstall the operating system. Everything went well until I entered the product ID for my Windows95 CD Rom. After pressing "Enter" I get "Invalid ID Number". It came with my system when I bought it a couple years ago, does this ID Number expire?? I called Microsoft 800 number, but being on the weekend no one was there to provide any guidance other than to contact my retailer. Why do things always break on weekends or holidays?? Anyway, now what. Would appreciate any suggestions, thank you...Jim Gray PCBUILD maintains hundreds of useful files for download visit our download web page at: http://nospin.com/pc/files.html
