Questions[windows-server-2008-r2](server)

Our credit card processor recently notified us that as of June 30, 2016 we will need to disable TLS 1.0 to remain PCI compliant. I tried to be proactive by disabling TLS 1.0 on our Windows Server 2008 R2 machine, only to find that immediately after reboot I was completely unable to connect to it via Remote Desktop Protocol (RDP). After some research, it appears that RDP only supports TLS 1.0 (see here or here), or at least it's not clear how to enable RDP over TLS 1.1 or TLS 1.2. Does anybody know a way to disable TLS 1.0 on Windows Server 2008 R2 without breaking RDP? Does Microsoft plan support for RDP over TLS 1.1 or TLS 1.2?

Note: There appears to be a way to do it by configuring the server to use the RDP Security Layer but that disables Network Level Authentication, which seems like trading one evil for another.

UPDATE 1: Microsoft has now addressed this issue. See the answer below for the relevant server update.

UPDATE 2: Microsoft has released a tutorial regarding SQL Server Support for PCI DSS 3.1.

Is there a way to send the Ctrl-Alt-Del command to an RDP session (Windows Server 2008 R2) inside another RDP session (also Windows Server 2008 R2) without the first session catching it?

Ctrl+Alt+End and Ctrl+Alt+Shift+End do not reach the 2nd level session.

Top-level environment is Windows 7 Enterprise.

I have some tasks in the Task Scheduler on Windows 2008 R2. I created them as the admin and I'm logged in as the admin. I have no easy way to rename the tasks. The only way I can is to export the task config to a XML file and re-import to a new task, change the name there, then delete the old task. Is there an easier way?

I have a scheduled task which is very CPU- and IO-intensive, and takes about four hours to run (building source code, if you're curious). The task is a Powershell script which spawns various sub-processes to do its work. When I run the same process interactively from a Powershell prompt, as the same user account, it runs in about two and a half hours. The task is running on Windows Server 2008 R2.

What I want to know is why it takes so much longer to run as a scheduled task - more than an hour longer. One thing I noticed is that the task scheduler runs at Below-Normal priority, so when my task starts, it inherits the same lowered priority. However, I've updated the script to set the Powershell process priority back to Normal, and it still takes just as long.

Anybody have an idea what could be different between the two scenarios? I've ruled out differences in processor and IO load - this task is the only thing the system is used for, so there's nothing else running that could be competing for resources.

What are the major differences between Windows Server 2008, 2008 SP2 and 2008 R2?

Are the code bases for these OSes different?

If I'm developing applications for any one of these three, should I be worried that it might not work on the other two?
