now, what's easier to just write a patch which allows these programs to= run=20 as before

or to adapt them all to the new OS ?

Just count the total programming time needed !

but well, maybe that's how Microsoft wants to hold down competing=20 software.

but can't we just include some old platform to support the old=20 DOS-programs ?

switch from Vista back to an XP-like-cmd.exe and then back to Vista= on=20 exit

Even if you -maybe- could easily write Vista-programs from now=20 on,

old programs from decades of DOS-programming would be lost !

Thousands of hours of programming, research, old papers and=20 references

can't be verified etc.
