Here's your To Do List:

Reset IE

Uninstall all downloaded programs that you can ... like tools that are suppose to clean, repair, optimize, or tune-up your PC.

Run download and run the following programs: Malwarebytes Anti-Malware, Emisoft Anti-Malware.

Install, update, and run an anti-virus program (I like Avast! Free).

Turn on windows firewall

Try to use the registry editor. If it fails again, Create a new administrator account and try to run it as that user.

Post any problems you run into. This may be a long process, so don't be shy to ask for more details.

Good Luck

Or possibly you have some malware which is trying to hide itself by that simple trick. Here is another sign of it:
O7 - HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System, DisableRegedit=1
==Please download Malwarebytes' Anti-Malware
from: http://www.majorgeeks.com/Malwarebytes_Anti-Malware_d5756.html
or: http://www.besttechie.net/tools/mbam-setup.exe
=Dclick that file, mbam-setup.exe, to install the application,
-ensure that it is set to update and start, else start it via the icon, and UPDATE it.
Select "Perform QUICK Scan", then click Scan; the application will guide you through the remaining steps.
ENSURE that EVERYTHING found has a CHECKMARK against it, then click Remove Selected.
If malware has been found [and removed] MBAM will automatically produce a log for you when it completes... do not click the Save Logfile button.
Examine the log: if some files are listed as Delete on Reboot then restart your machine before continuing.
Copy and post that log [it is also saved under Logs tab in MBAM].

If you find that you can't complete any of these tasks, it may help to do the following and try again:

Hold the windows key and press R

Type the following and press ENTER: msconfig

On the Services tab,
-check the box to hide Microsoft Services and then
-click the button to Disable All

On the startup tab,
-click the button to Disable All

Click OK and you will be prompted to restart the computer.

After you have re booted and removed malware, you will want to open the Microsoft configuration utility and check the box for normal startup on the General tab.

** Note that some programs will not work while items are disabled via msconfig including most anti-virus programs! That's the point ... malware are programs too! If you know which services and startup items belong to your Anti-virus Program, you could check them, so they are not disabled with everything else.
Good Luck
