I need to downgrade from explorer 7 to explorer 6 on my HP computer

HP does not have software or driver downloads available for your computer with Windows 7. HP provides software and driver updates for the operating system that originally came with the computer. Changing the operating system on your computer (upgrading or downgrading), puts the system into a configuration that might not work with the hardware design. If you you must change the operating system, get drivers from the manufacturer of the component you need. For example, if a computer has NVIDIA video hardware and was upgraded to a newer version of Windows, someone would go to NVIDIA's web site to download and install an updated driver.

Format c drive and reserved drive, reinstall windows 7

Pl note that only Windows 7 Ultimate or Professional supports downgrade rights to Windows Vista Ultimate, Business or Windows XP Professional.
You can do a downgrade as long as you have a full version Windows Vista license.

If you are referring to Windows 7 downgrade rights, this option is specific to the manufacturer, computer model and the edition of Windows 7 you have installed.

If the OEM is not making a driver then your probably out of luck. You may have to go back down to Win XP or sell or return the item. Not all manufactures have caught up with Win 7 drivers so you need to make sure there is a driver for the equipment you purchase.

Internet Explorer 8 is part of Windows 7. If you removed IE9, you probably just downgraded to IE8. What happens if you run Internet Explorer?

You would have to buy yourself a copy of XP pro and do an OS reinstall. The XP pro should come with a COF key. When you do that you will need to install all the drivers for your computer. Check at the manufacturers website and download all the drivers for your PC that work with windows XP. Do this first then do the OS install.

do you use HP Director for HP Printer ? IF so, the HP Director may not work now as it is for long stopped by HP for Scanning use.

You can try this patch from HP Website for HP Director

try the above patch and restart your pc and try HP Director.
OR else
You will have to download the latest drivers from HP website and install them

Before downgrading from Windows Vista to Windows XP you should always confer with your computer's manufacturers website to look up your model and see if they support the downgrade. Often times the only way for you to downgrade is to have it done before receiving the computer, since a majority of the hardware on the laptop is made specifically for Vista and is not backwards compatible. Looking on the HP website, I see that they only offer a very limited number of Windows XP drivers for your system, which tells us that downgrading is not possible.
I would recommend that you consider not downgrading but rather upgrading to Windows 7 as it is a much more stable and functional OS than its predecessor Windows Vista. You can even run Windows 7 in Windows XP compatibility mode so you can enjoy the benefits and upgrade of Windows 7 but still have the Windows XP feel and functionality. I will be writing a How-To/Tip on Windows XP Compatibility mode today so you can be on the lookout for more information on that.

If the problem happens with only one specific web-site, then avoid that web-site.

Otherwise:
Click Start
Click Control Panel
Click Classic View
Click Add/Remove Programs
Select Internet Explorer
Click Remove

This will "downgrade" your computer to an older version of Internet Explorer. Try the web-site again.

In a day or two, Windows Update will "upgrade" you, by installing the latest version of Internet Explorer. Perhaps, this "re-install" will fix the "error".

Do you have internet explorer version 7 installed on your computer?
HP Director has a compatibility issue with Internet Explorer 7. Please refer to this document if u have Internet Explorer 7 installed on your PC.
