List of Changes in Windows 8

Someone made a nice listing of changes in Windows 8… Source: http://www.grouppolicy.biz/2011/09/what-is-new-in-windows-8/
  • sub-32bit video color is no longer supported in Windows 8
  • XDDM video driver will no longer work in Windows 8 (XDDM seems to be 2000/XP video drivers…why you would you use these in Windows 7/8 anyways?)
  • Upgrade of video driver in Windows 8 will not lose SYNC with monitor…
  • Display Drivers can be Full, Render Only and Display Only
  • True headless servers are now supported. Interrupt 10 is handled by stub driver of VGA driver.
  • Video Driver crashes can be isolated to a specific engine rather than the whole driver.
  • Windows To Go – You will be able to run full copy of Windows off any 32gb USB Storage device. This means you will be able to take your computer with you in your pocket and just plug it into almost any computer.
  • USB 3 is now fully supported.
  • WiFi Direct is now supported. This will allow you to connect any two WiFi direct devices without an access point.
  • You can project any HTML5 video to a play-to device with Windows
  • NVIDIA Windows 8 ARM based systems support TPM (This was a channel 9 video).
  • Bitlocker Network Unlock in Windows 8 will be great. If the computer is plugged into the LAN no start-up PIN will be required.
  • 15.6ms wake timer is gone during sleep mode therefore better battery life.
  • Connected standby allows you apps to sleep but then periodically wake up and check for new information so they stay up to date.
  • SMB 2.2 will allow you to load balance all SMB traffic over multiple NICs
  • Built-in NIC teaming support
  • Server comes in 3 modes: Full Shell, No Shell (only management tools) & Server Core. This means all certified server products must be able to run without a Windows shell.
  • Servers are now configured using PowerShell and this is driven using Server Manager.
  • Server Manager will allow you to manage multiple servers at the same time.
  • Using PowerShell or DISM you can move add/remove the shell
  • Windows 8 will have an AppStore: very similar to Windows phone.
  • Hyper-V servers will support VHD’s on SMB Shares. This means you can run a live migration fail over cluster without the need to use iSCSI or Fibre Channel SANs.
  • All Metro App’s will be able to save application configurations to SkyDrive. This allows your metro settings to roam between computers. This does NOT replace traditional AppData folder.
  • RemoteFX will work over a WAN and has greatly reduced bandwidth requirements. It can also use UDP packets for transmission of videos.
  • Hyper-V Virtual Network allows you to migrate hosts from on-site to off-site without having to re-IP the servers. A virtual network tunnel will be established between both sites that allows the same subnet to span multiple geographical locations.
  • Single instance storage is now supported. Put your VHD files on a SMB file share and enable de-duplication and reduce the storage requirements overnight. This also works for all other files types such as the MS Office file format.
  • Hyper-V is now supported on the Windows 8 (client)
  • Secure Boot ensures that the whole boot process is secure. This prevents malware/rootkits from being able to install before the OS starts. This leverages systems with a TPM chip.
  • TPM can now be used to store certificates to ensure that malware cannot access these certificates. The is protected via a password with a hammer timeout
  • Add multiple USB 3 devices and then pool them together for a high performance disk drive.
  • Memory chips can now be put into low power mode saving power on a system.

Windows 8 Developer Preview Available for Download

Should be up tonight:

http://www.winsupersite.com/blog/supersite-blog-39/windows8/windows-8-developer-preview-build-today-140553

Updated 9/14/11: Don’t bother.  Very early release.  Couldn’t get most of the tiles to work in Metro.  Classic start menu was missing.  Did like the ribbon in the new explorer.  Disliked cheesy Metro style UI.

Case of the Slow File Upload from Internet Explorer

A fun little case of files uploading very slowly from Internet Explorer.  To rule out the web site being the issue, I tried doing the same action within a VM and it would complete in 1 second versus 60+ seconds on the troubled PC.  Checked the network icon in the task bar and it was showing it was connected at 100Mb.

Did the full gambit of upgrading Internet Explorer from 7 to 8 and purging/tweaking the registry with anything Internet Explorer related, including this KB at Microsoft: http://support.microsoft.com/default.aspx?scid=kb;en-us;329781.  Alas, nothing was working. I pulled out Process Monitor and ran a scan on a “good” PC and the “bad” PC.

Here’s the good one:

and the bad one:

 

As you can see in the 2nd picture, Internet Explorer is having some serious network problems.  The problem?  Well, it was either the network jack, line or the port on the switch (all network connections should be full-duplex, not half-duplex):

Unfortunately, Windows will tell you the connection is 100Mb, but not if it’s full-duplex or half-duplex by looking at the network connection status. Moving it to another network jack and patching it into another port on the switch fixed the issue.
