I understand you receive an error message 0x80072EFE when trying to installing update from the Windows Update website. This kind of issue may be caused by hardware/software firewalls or proxy server or Windows category files are corrupted. Let’s try the following steps to resolve this issue.

Step 1: Check background programs.
=======================
Disable firewalls or other Internet browser programs that can affect the Internet connection. The following programs can affect the connection to the Windows Update site and I suggest you remove or disable them:

McAfee firewall
Norton Internet Security
Zone Alarm Firewall
Panda firewall


Step 2: Delete the CatRoot2 folder
=======================
A: Stop Cryptographic Services:

1. Click Start, click Run, type in "SERVICES.MSC" and press Enter.
2. Double click Cryptographic Services, and then click Stop (if it has been started).

B: After stopping Cryptographic Service, please delete the "Catroot2" folder:

1. Locate the "C:\Windows\System32\" folder.
2. Delete the Catroot2 subfolder in System32.

Note: I am assuming your Windows Vista is installed in C:\Windows.

C: Re-start Cryptographic Services:

1. Click Start, click Run, type in "SERVICES.MSC" and press Enter.
2. Double click Cryptographic Services, and then click Start.

After performing the above steps, please visit the Windows Update website and check the available update.

Hope this helps.

I have sis 661fx Motherboard with intel 3.06 GHz processor with 1gb Ram.I have installed Win 7 last month.The Aero feature is not working on my system.i tried to update the drivers but wen i troubleshoot...


Did you run the Windows 7 upgrade advisor before you installed Win 7. You may find that windows 7 doesn't allow the use of your graphics hardware. With the issue of Win 7, Microsoft decided that they would only allow the use of hardware that had been tested by themselves. To enforce this all drivers for Win 7 onwards require "Signed Drivers" to operate properly. You may need to buy a Win 7 ready graphics card to continue with a stable computer.

My idm is block due to fake serial number


if you purchased the Windows 7 someone might have stolen the license before you got it by random key generation or something similar and it should be returned immediately to the store for a valid license copy.
If that is not the case then........
It almost sounds like you have a hacked / cracked version of Windows 7 Ultimate, if so I would recommend buying a new copy or re-installing windows. Once that error occurs it can only be fixed by re-installing. and after you re-install watch out for a certain windows update (im not allowed to say which one)that will break the special fix and hide it in your updates so it does not re-occur until you can buy a *Licensed copy* of Windows.

How to fix an error 80072efe? It is an update problem when i try to update my laptop i keep getting this error.


There is a very good chance that you are seeing the effects of a hijackware infection!
Microsoft PCSafety provides home users (only) with no-charge support in dealing with malware infections such as viruses, spyware (including unwanted software), and adware.

Also available via the Consumer Security Support home page: https://consumersecuritysupport.microsoft.com/
Otherwise...
1. See if you can download/run the MSRT manually: http://www.microsoft.com/security/malwareremove/default.mspx
NB: Run the FULL scan, not the QUICK scan! You may need to download the MSRT on a non-infected machine, then transfer MRT.EXE to the infected machine and rename it to SCAN.EXE before running it.
2a. WinXP => Run the Windows Live Safety Center's 'Protection' scan (only!) in Safe Mode with Networking, if need be:http://onecare.live.com/site/en-us/center/howsafe.htm
