Win x86 Compatibility is a Joke on 64 bit system
XP Pro and Media Center systems may be a different story.
I was meaning Home and that flavor of XP. Even XP Pro is missing a lot compared to Pro Vista and Win7.
The original XP Home used a much smaller swap file and SP3 can use a lot of your ram just loading the register file. Just look at how much space a Restore Point takes.
I am working on a compatible app for the WinForce Control Panel that will make the older XP software work on the new systems. The Win Compatibility is a Joke, and I have yet to see it work for running a 32 bit app on a 64 bit machine. Please let me know if you have had better Luck.
I have been able to make all of my older software run on newer systems using some software tricks and reg edits.
Running Win98 apps on Windows 8 can be done, But I have removed 98 software support because very few people use it, and I had to write too much code just to support it.
I just hate how they make you buy something that you don't really need.
If you have good hardware, You can make the software work.
When you run win 98 on a new computer it takes about 3-6 seconds to boot.
Wonder if the new OS's have a little overhead ?
