Recently, many customers reported the Windows Firewall issue. This seemed to be caused by a wide spread malicious application.

Symptom:

The error message "Windows Firewall can't change some of your settings. Error code 0x80070424" will pop up when you try to change the Windows Firewall settings. In the meantime, when you restart the system, it might pop up an error saying that "Base Filtering Engine Service" could not be found in the system.

Please note that the same error code could pop up when you try doing anything in Windows Defender.

Resolution:

Download the registry files (You can also export HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\BFE from another working Win7 PC)
1055.BFE.reg

0677.mpssvc.reg

Launch and import them to registry

Restart your PC

Now,open RUN and type

regedit and click ok

go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\BFE

Right click on it-permissions

Click on ADD and type

Everyone and click ok

Now Click on Everyone

Below you have permission for users

Select full control and click ok

Now,open RUN and type services.msc and click ok

start base filtering engine service and then windows firewall service

Good luck

Note:Modifying REGISTRY settings incorrectly can cause serious problems that may prevent your computer from booting properly. Microsoft cannot guarantee that any problems resulting from the configuring of REGISTRY settings can be solved. Modifications of these settings are at your own risk...

Threads that you can reference:

1. Shut down the virtual machine in Windows Virtual PC, so to exit the Windows XP Mode.

2. Open a command prompt window with elevated privilege.

3. Run the following command 

cd /d "%localappdata%\Microsoft\Windows Virtual PC\Virtual Machines"

REM make a copy of the configuration files

copy "Windows XP Mode.vmc" "Windows XP Mode.vmc.backup"
notepad "Windows XP Mode.vmc"

4. Modify the number in the following sections. For example, you have a computer that has a resolution rate of 1280x800, you can adjust the following numbers to 1024x640 in the ratio of 16:10. This makes Windows XP Mode display more properly in Windows mode. 

 "<resolution_height type="integer">768</resolution_height>"

 "<resolution_width type="integer">1024</resolution_width>". 

5. Save the configuration file.

6. Restart Windows XP Mode

This is an interesting issue of Windows 7.

Some customers reported that in the Power Options they have chosen 'Never' for 'Turn off the display'. However it keeps resetting itself to 20 minutes.

After further investigation, it was proved to be a compatibilty issue of HD Tunes Pro. That software is for hard drives testing and each time any test starts it resets power options.

Symptom:

When you are migrating mail boxes from your Exchange server to Plan E3.

• You've implemented federation (AD FS) in your on-premises organization.
• Your are doing a staged Exchange Migration (using a CSV file).
• In the CSV file, you're using TRUE for the value of the ForceChangePassword attribute.

You might get the following error:

A Windows Live error occurred while provisioning for "mail@domain.com". An internal error occurred while talking to Windows Live. Additional details: "0x800482101033This action is currently blocked for the API.
CH1IDOPRTI02 2011.07.22.15.10.19

Resolution:

Modify the CSV file, change the value for ForceChangePassword to FALSE, and then rerun the migration.  For example:

EmailAddress,Password,ForceChangePassword
pilarp@tailspintoys.com,Pa$$w0rd,False
tobyn@tailspintoys.com,Pa$$w0rd,False
iant@tailspintoys.com,Pa$$w0rd,False

Alternatively, you can remove the Password and ForceChangePassword columns. The documentation for staged Exchange migration will be updated accordingly.
