When I worked mostly from home in 2001-2003, my home PC didn't have the same commonly used programs as my office PC. This was, mainly, Word and Excel. They gave me a copy of Office 2000 which included Word 2000 and Excel 2000. I had a much older version of Word on my PC and had no Excel on it.
I still have the Office 2000 CD which still works and I have (re)installed it onto my PC many times, whenever I bought a new PC or a new hard drive. The CD is 20 years old at this point, but both programs work just fine, even on Windows 10 machines.
They also gave me Lotus 2000 to put on my PC because I had some old Lotus spreadsheets I still used and couldn't convert to Excel. For my home use, I prefer Lotus because I find it somewhat easier to use although some spreadsheets are more suitable for Excel.
