Test Layout

I have a test environment setup using Hyper-V. I regularly add and remove virtual machines from this Hyper-V host. When you delete a virtual machine in the Hyper-V Management console, it does not delete the files. You need to delete the files manually afterwards. A significant percentage of the time, I receive an Access Denied message when deleting the VM files. Even though the VM is deleted, I cannot remove the files.The happens because Hyper-V has locked the files. To unlock the files and allow the files to be deleted you can: Restart the Hyper-V host Restart the Hyper-V Virtual Machine Management service on the host

I have not yet tested it, but since Windows Server 2012 has PowerShell v3 installed, this SP should also allow PowerShell v3 to be installed on other versions of Windows Server. http://blogs.technet.com/b/exchange/archive/2013/02/12/released-exchange-server-2010-sp3.aspx UPDATE: Nov 27, 20...

My experience lately has been that many viruses/malware only infect the profile of the user that was logged on at the time of infection. This is due mostly to the security of the operating system and browser which generally limit activity to the user profile. However, even older XP machines with users running as a local administrator benefit when the malware assumes that it needs to infect the user profile rather than system files. If malware is limited to a profile, it makes removal of the malware much easier. Log off as the infected user and log on as a user that is not infected. If the malware is only in the user profile this is just as effective as scanning the hard drive externally from another computer. Today I had the pleasure of dealing with System Progressive Protection. It is very aggressive fake antivirus software. Once it is in the system, you can't run most tools because it blocks them. However, it was limited to the user profile. When I logged on as another user the s...
