Correct colour management?

Currently I shoot in sRGB and use CS4 to edit the images.

I work in CMYK and upload a view pictures to the web but in internet explorer they lose some saturation.

I can corect this by proofing in Windows RGB and then uploading them to the site.

Is this the correct thign to do and is this the same for most of pc's that will view the site as well?

No, this sounds all wrong.

Firstly, why are you working in CMYK? That's strictly for the printing industry, and definitely not for wedding photographers, which your signature mentions that you are. CMYK is a difficult beast, and best avoided.

You have a great deal of reading ahead of you, my friend. Start with the "Color Problems?" sticky at the top of this forum.

Do everything in sRGB until you have good reason (and understanding) not to do so. And make sure you calibrate your monitor with a hardware device, if you haven't already done so.

I hope this helps.

Stop using CMYK, use RGB and specifically the sRgb color space until you've read a book on color.

Cool, thanks guys, it probalby fell that way when I was sorting my business cards.

Well, for business cards an argument might be made for working CMYK, provided the printer provedes you with his specific profile.

Just had my own set printed, edited in CMYK, and they look very, very close to both the softproof on screen and the proof I printed on my R2880

For web, don't even think about CMYK.

Save for web, as I explained it here: http://www.getcolorman​aged.com/color-management/saveforweb/
