Theoretically, Windows 7 should have generated automatically restore points before driver installation, so you can revert back to when you had just done the Windows Update but BEFORE you ran the Intel update utilities. Or at most BEFORE the Windows Update, so you'll have to download that updates again. follow the System restore tutorial
Then, it is usually better to stick to what comes from Windows Update. It gives you stuff a bit after the time when it is still fresh of the press but it's less likely to give you potentially unstable/bugged drivers like the installers from the device manufacturer (like Intel) or the outdated drivers from the laptop manufacturer's page.
Assuming Windows Update does
have those drivers, but for most laptops it's the case.
