Iphone Update Regret

For about a year I have resisted temptation to update my Iphone 5s everytime I plug it into Itunes on my lappy which is a bit dated now and on Vista OS.
Last night I gave in and let it update, whilst it was doing it I was faffing on Itunes with my music. When it had finished, I plugged the phone back in to update the changes I had made, Itunes then announced my Itunes needed updating also in order to recognise my phone so I checked for new updates but it had the latest version.
Confused, I investigated this online and it turns out I cannot update it ever again because newer versions require Windows 7.
I downloaded the program from Windows that assess whether or not this was possible on my laptop which it is if I update this that and the other program at great expense and really not worth it in my opinion.
So as I have reluctantly ruled this option out am I to assume my Itunes and Iphone will never be able to talk to each other again unless I buy another laptop with Windows 7 or an Apple lappy as I guess I can't undo the update on my phone?
Please can someone help me find a resolution to this?
I did think about factory resetting the phone but worried I will lose stuff Shocked(

We only lose what we don't backup.

So backup via alternatives like IRIP (see google) and google this -> ITUNES ALTERNATIVES.

Sounds Like a Plan

I didn't know there were alternatives! I'll Google it and take it from there. Thanks mate Shocked)

Modern up

Skooby, don't take this personal. I'm no big expert, but if you're still using Vista, it's time to upgrade but not to Windows 7. I'm a little surprised your computer still works at all, but it's got to be slower than snails. Vista came out in January 2007. Windows 7 followed in 2009. That's ancient stuff that you can't expect to work well with modern equipment. Upgrading to Windows 7 is like buying a '59 Chevy to replace your '57 Chevy. They were great cars in their time, but their time has past. I think you need to bite the bullet, get a second or third job and buy a new computer with the latest software. I think you'll be amazed.
