Updating my windows xp
Most PC experts will recommend you start fresh and "pave" your machine anyway.I think this is a hassle, but in the case of XP to 7, it's necessary.We strongly recommend that users upgrade to a newer version of Windows that is still supported by Microsoft in order to maintain a stable and secure environment. As noted, users may still continue to use Java 8 on Windows XP at their own risk, but we can no longer provide complete guarantees for Java on Windows XP, since the OS is no longer being updated by Microsoft.Customers with a support contract may be required to reproduce an issue encountered on Windows XP on a later version of Windows, and if the issue is specific to Windows XP Oracle is not required to (and may be unable to) issue a patch or a workaround.Specifically, the section on Upgrading from Windows XP to Windows 7 is what I needed.The "Windows Easy Transfer" application is on the Windows 7 DVD in: They probably named it to make sure it wasn't named and save some trouble with confused folks, but still, it was a smidge counter-intuitive.See Third Party Vendor-Specific Support Terms on Oracle Software Technical Support Policies (pdf) for details.
The machine is 3-4 years old, so I didn't think a Windows 7 install would be unreasonable.
Fortunately I had a small external hard drive, so I just used that since both the "old" and "new" computer were the same machine.
I was then asked this very tricky question, for which there is only one answer.
As of April 8, 2014 Microsoft stopped supporting Windows XP and therefore it is no longer an officially supported platform.
Users may still continue to use Java 8 updates on Windows XP at their own risk, but we can no longer provide complete guarantees for Java on Windows XP, since the OS is no longer being updated by Microsoft.
