If you uninstall IE 7.0, then you will have to reinstall IE if you want it back, it doesn't matter what version. But once IE is uninstalled, it is gone until you reinstall it.
Well for one, it would have been better not to install version 7.0 in the first place, since it's still in beta mode (meaning there may be bugs within the program) But here what you do, go ahead and save the download, don't run it just save it to your hard drive or to a disk. The go and uninstall 7.0. If IE version is gone, 6.0, go ahead and run the download.
No version of Internet explorer will be left on your computer if u uninstall IE 7.0.
you can't uninstall IE 7.0 beta....... system restore can do though don't worry you'll get back to IE 6 no need to download it.....
In the past if you upgraded to a newer version of IE, the old version is replaced and gone forever. I like the suggestion to download IE 6 and save it before deleting IE 7. If you delete 7 and 6 is still there, great! But if 6 is also gone, you've already got it saved.
