It looks like the Windows Defender in Windows 8 won't upgrade the signatures automatically, if Windows Update is set to "Notify, but don't install the upgrades".
Is my impression real? Is there is a fix?
I don't like automatic updates as I don't want to install useless updates like the ballot screen or something else, I want to choose.

I have a service that needs to be started only AFTER another service. Is there some way to configure the service to only start once another has finished starting?
Obviously, I could use a delayed start or write a batch script to do this, but they are both messy / temporary solutions. So I wondered if I can schedule for this to happen somehow?
Can it be done?

My problem is that wiping the drive takes 1.5 days, and I absolutely need to have my computer off during the night. My fan is too noisy, my room is very small, and I sleep next to the computer.
Is it possible to wipe a hard drive with pauses in-between? I can't see that CCleaner, DBAN or Eraser has this functionality.

If I have a system with let's say two Quadcore CPUs and HyperThreading enabled, how do I know how the phsyical and virtual cores are sorted? For example if I force a process to run on "CPU 0" how to know which Core this really is? I remember a complex drawing about this, but didn't find anything useful.
Update:
After discussing this with a programer I'm convinced that it doesn't make sense to bind a program/thread to a specific core. In most cases it's better to let the operating system decide what core(s) to use. However it would still be interesting how the enumeration works.

I've just discovered Motion and it works like a charm.. My only problem is that I'd like it to be active only during night-time, but there's no parameter for scheduling..
I think I could write a program that would control Motion via its "HTTP API", but I was wondering if someone had already done that, or if there's an alternative solution.
Thanks in advance :)

Our base system runs on Linux but unfortunately the UI has to be on Windows. Its a long story. But thats the requirement. So our idea was to run Windows in a virtual machine using VirtualBox or Xen. Because of our real-time performance constraints, we want to isolate the virtual machine to a single processor (in case of a multi-processor machine) or a processor core in case of a multi-core processor.
Is something like this possible? Can processor (core) affinity be set on the process running the virtual machine? Is one virtualization platform better than another for this requirement. I am confused with Xen, KVM, VirtualBox, OpenVZ, etc.

Is there an easy way to schedule downloads through the 'Ubuntu Software Center'?
For example: mark a number of programs for download and installation between 2am and 8am?

I am not asking how to nice and renice a command on UNIX.
What happens is that on a particular machine into which I frequently log I am only allowed to run long-running processes with low priority (nice 19). Is there a way for all my commands on this machine to run as if I had "niced 19" them?
Inevitably I forget to prefix the command with "nice 19" when I start it, then need to go muck around in ps/top to locate the pid of my resource-hogging process and then renice it. Too much trouble, and I risk annoying the sysadmin; is there a way to do this by default?
many thanks!

How can I launch Windows Media Player or iTunes, playing a song, with the Windows task scheduler.
I already know how to create a task and how to trigger it at a given time (launching iTunes / WMP).
But not how to automatically start playing music.
Can someone help me please?

Is there any easy way to schedule repeated jobs in Mac OS X?
I know I could use cron, but I'm looking for a more user friendly way to do it, a GUI for schedules, something like this.

Is there a way to schedule/automate system image backups in Windows 7 Pro? Or do I have to do it manually every time?

To put it short: I'd like to schedule my windows updates to start/stop at certain times of day. How can I do this?
More explanation: This is because my internet traffic is limited by ISP and it's free only during a specific period throughout the day (2:00am-7:00am). I've set windows update setting to check for updates but notify me before downloading in order to prevent it from automatically using up my traffic. But then I have to manually tell it when to start downloading. I obviously don't want to stay up that late just to push a button.
So again, how can I schedule windows updates to start/stop at specified times?

What's the Windows equivalent to cron, or for those of you unfamiliar with Unix, how does one schedule a program to run at regular intervals?
