How to add a role or feature on Windows core
one of the ways is to use disk. Another is to use ocsetup. Below is an example of disk usage:
dism /online /enable-feature /featurename:snmp-sc
NETSH set DNS servers priority by index
example for the interface named "LAN", we set higher priority one DNS
netsh interface ipv4 add dnsserver "LAN" static 192.168.0.254 index=1

Powershell script to extract table from html
had to extract table from HTML and this is what I came up with for a particular case:
Note that I had to twick original html files from Cp-1252 to Unicode - using utility from http://sourceforge.net/projects/cp-converter/ I used http://powergui.org/ to debug the script

Windows 8 is essentially Windows 7 with new GUI
For the set of old apps Windows 8 is the same as Windows 7, I was able to install without any problem, SAP GUI 7.20, TrendMicro antivirus. There is embeded Windows Defender in Windows 8, but it has to be switched off to let Trend to run.
The magic is unlocked when you have real "METRO" app in hand. Then Windows 8 (with WinRT) will shine differently. As you know, WinRT gives an asyncronous framework for fluid interface, it is more secure, as it run apps in isolated enviroment where not all user right are immediately given to an app, etc, etc.

Windows 8 Enterprise first look
Hi, I'm trying to install Windows 8 Enteprise from the DVD I received from Microsoft about a month ago. Looks good, setup is hyper easy.
Now I need to activate it and booms! I do not have Volume activation in my network. Actually there is a update that fixes that http://support.microsoft.com/kb/2757817, but it is not available in our company.
This article explains how to deal with this situation:
http://blogs.technet.com/b/keithmayer/archive/2012/08/24/tip-of-the-day-microsoft-windows-8-enterprise-activation-itpro-windows8.aspx
Let me try first with mak, since this is a test lab install....and it works! Windows 8 is activated with mak.

Junkmail GPO in Outlook
http://www.effectusdigital.com/outlook-junk-mail-filter-through-group-policy/
as explained above, do not forget registry JunkMailImportLists otherwise it will not work...
update from http://forums.msexchange.org/m_1800545996/printable.htm:
We got an update from Microsoft -- they say that the best option is:
New-TransportRule -Name ' Flag internal email domains as not junk and set SCL to minus 1' -Comments ' Flag internal email domains as not junk and set SCL to minus 1' -Priority '0' -Enabled $true -FromAddressContainsWords 'domain1.com','domain2.com' -SetSCL '-1'
The reason why email from our own internal domains is being flagged as junk is because the emails are being send un-authenticated and are not really "people" with AD accounts. They are 3rd party internal applications that cannot send/use authenticated senders.
So "white-listing" internal un-authenticated email seems to be the option to go with until we can replace this legacy software or find ways to convert them to authenticated senders.

Spyware?
Just discovered a great tool from Kaspersky: Rescue disk CD/usb - it can scan Windows 7 disk and update databases online. I regret that I did not use it immediately before spyware deinstalled itself...
Spyware?
Interesting case today, where the PC was slow, with high hdd activity and very strange traffic with task Id 0 to IP 50.56.48.215 and 68.232.34.73 and possibly others. Few days ago this PC was highlighted by snort as
"SPYWARE-PUT Trackware casalemedia runtime detection"
PC is protected with Trend. After sucessful installation of Lavasoft, I realised that it actually did not install, folder is absent. Second time, the same result. Somebody is playing jokes? Third time it was installed ok and suddenly strange activity stopped, as if it deinstalled itself to avoid detection.
Further scan with Lavasoft and Kaspesky did not uncover anything. Puzzle...
