Installing .Net 3.5 Fails on Windows 8 With 0x800F0906 Error

Windows 8 and it required .NET 3.5.  I tried to install it (both download and from Programs and Features) and the installer tried to download the code.  The download would fail with a 0x800F0906 error:

Windows couldn’t connect to the Internet to download necessary files. Make sure that you’re connected to the Internet, and click Retry to try again.

Some googling ensued and I found a fix.  Pop in the installation media for Windows 8 and run DISM from an elevated (admin) command prompt.  E: was the path to my Windows 8 installation USB.





Not exactly user friendly!  The Live Essentials 2012 install worked fine after that.
It appears that this is caused by the machine being policy configured to use WSUS or similar with the download of .NET 3.5 not being available.

Creating Windows UEFI Boot-Stick in Windows

Preparing the USB Stick

In order to use DiskPart, open the command prompt as an administrator and then follow these instructions:

1. Enter the following command in the CMD window:
   • diskpart
2. With this command you can display the list of drives.
   • list disk
3. Now, identify your USB stick and enter the following command as a number (instead of "#"):
   • select disk # example
4. You can delete all existing partitions from the USB stick with this command:
   • clean
5. With this chain of command, a new partition is created, then selected, activated and then formatted to FAT32. A drive is subsequently assigned when the procedure is completed:
   • create partition primary
   • select partition 1
   • active
   • format quick fs=fat32
   • assign
6. Now you can exit Diskpart:
   • exit

Copying Windows installation files onto the USB stick

Next, Windows installation files need to be copied to the USB stick.

Here is an example of how you can copy the files via Windows Command Prompt from the mounted ISO file or from the inserted Windows DVD to the USB stick:

• Drive D: for the mounted Windows ISO File / Windows DVD
• Drive F: for the USB stick
  • xcopy d:\* f:\ /s /e

The USB stick is now ready for the "normal" BIOS-based Windows installation. The necessary steps for UEFI-based installations are listed below.

Preparing the USB Stick for UEFI

Check if the file 'BOOTX64.EFI' via the path \EFI\BOOT\ is available on the stick.

If this is not the case, you can copy the file to the stick by using one of the two methods below:

• If access to the stick is via a UEFI-enabled computer with a Windows 7 (or higher) x64, the Bootloader can simply be copied and renamed to the stick. You can do this on the system partition under: C:\Windows\Boot\EFI for the file 'bootmgfw.efiand copy it to the stick in the \EFI\BOOT\ folder and rename this file BOOTX64.EFI.
• The file bootmgfw.efi can also be extracted from a Windows 7 (or higher) x64 - DVD. It is located in the 2.7 GByte large archive Install.wim in the subdirectory \sources. The archive can be extracted with an archiving program. This file is located in the subdirectory "1" of the archive at 1\Windows\Boot\EFI\.

“SecureBoot isn’t Configured Correctly” Watermark Showing on Windows 8.1 Desktop

Today we are going to address one of the most annoying and frequently faced problems ofWindows 8.1 operating system. There are many people who installed or upgraded to recently released Windows 8.1 OS and started facing a weird issue.

Suddenly a watermark "SecureBoot isn't configured correctly" starts showing on their Desktop. This text message is shown in lower-right corner of Desktop as shown in following screenshot:

Windows 8.1 Pro
SecureBoot isn't configured correctly
Build 9600

Users have no idea why this watermark appears on Windows 8.1 Desktop? There is no way or option available in Windows 8.1 Settings to remove this watermark from Desktop.

Actually "Secure Boot" is a new security feature of Windows 8.1 which helps users in increasing the security of their computer system. It automatically prevents unauthorized software from running in Windows. But this feature can only be used if your computer BIOS supports it. If you see "SecureBoot isn't configured correctly" watermark on Desktop, it means this feature has been disabled from BIOS settings.

But sometimes the watermark doesn't go away even if you correct the settings in BIOS or your BIOS doesn't support this feature at all.

Microsoft has acknowledged this issue and released a hotfix "KB2902864" to solve this problem. Once you install this hotfix, it'll remove the annoying watermark from Windows 8.1 Desktop.

Windows 8.1 users who are having "SecureBoot isn't configured correctly" watermark on Desktop, can download this hotfix using following links:

• Download Link for Windows 8.1 (32-bit or x86)
• Download Link for Windows 8.1 (64-bit or x64)
• Download Link for Windows Server 2012 R2

Install the hotfix and restart your system. After reboot the annoying watermark will disappear forever.
