This week setting of the week allows you to prefer a custom logon background image in Windows 7. This setting is called “Always use custom logon background” and can be found under Computer Configuration > Policies > Administrative Templates > System > Logon.

Microsoft brought back the option to easily customise the logon background in Windows 7 as this was previously possible in Windows XP but it was removed with Windows Vista which left people with some pretty messy workarounds.

Once you have enabled this option all you have to do to create the “%windir%\system32\oobe\info\backgrounds” folder and populate it with a backgroundDefault.jpg image and your computer will then use that as the background image when logging on and off.

Note: Some sites will direct you to configured the OEMBackground or UseOEMBackground in the HKLM\Software\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\Background however this setting will negate the need to set this key.

Another one…? yes… Another roaming profiles group policy for this weeks setting of the week. But this is a really super cool policy I found while reading the “What’s New in Folder Redirection and User Profiles” (via @stealthpuppy ) document that Microsoft recently published. This document mainly goes through the new features with folder redirections in Windows 7 however it also mentions the new group policy/feature called “Background upload of a roaming users profile’s registry file while user is logged on”.

This setting can be found under Computer Configuration > Administrative Templates > System > User Profiles and is specific to Windows 7 or Windows Server 2008 R2.

This policy setting would be very useful as a way to ensure that at least part of a users profile is save to the network if they are they type that never like to log off their computer at night.

There are a few points about this policy which I have summarised below:

• Only synchronises the users registry profile (ntuser.dat) so things like desktop icons and favourites wont sync. (This is what folder redirection is for any way).
• There are two modes of scheduling the update
  • Run at set interval – Between 1 hour and 720 hours (30 days).
  • Run at specified time of day – useful if you only want to run this at 3am so that it only applies to users who stay logged on over night.
• The schedule will run randomly any time up to an hour after it is supposed to run so to not load the file server with a large number of concurrent requests.
• If you choose one method of scheduling then it will ignore the set value of the other schedule.

I also have a very strong suspicion that this setting is only compatible if you have Windows 2008 (or later) as the file server so that it can handle the copying of the locked file (ntuser.dat). Please ping me if you can confirm this.

This weeks setting of the week is a double header but they are really simple but so commonly used that they really have to be mentioned.

The first setting is found under User Configuration > Policies > Administrative Templates > Control Panel > Personalization > Prevent changing desktop background. As the name suggest this setting prevents users from changing the background image via the Display Setting control panel applications however it does not prevent users from right clicking on an image and setting it as a background image.

Recommendation: Enabled

If you really want to stop users from changing the background image then you also need to configure the “Desktop Wallpaper” setting to specify a background image which can be found under User Configuration > Policies > Administrative Templates > Desktop > Desktop (yes Desktop is there twice).

Recommendation:  Enabled (specify path to background image)

These setting should be configured for anyone want to implement a standard background desktop image of their SOE computers. However be warned if you are going to implement this setting then expect to cop a lot of flack from your users complaining they cant set their background image to their favourite family photo or even worse their cat.
