Some misinformation here. Windows Scheduler is perfectly capable of running tasks in the background without windows popping up and with no password required. Use this schtasks switch:. But yes, for accessing network resources, the best practice is a service account with a separate non-expiring password policy.
From the fine manual ,. Task Scheduler 2. NET development, I normally start off by developing a Console Application, which will run will all logging output to the console window. When it is run without this parameter, it acts as a Windows Service, which will stay running on my own custom coded scheduled timer.
Windows Services, I my mind, are normally used to manage other applications, rather than be a long running application. For one project I have been involved in the development of 8 or 9 Windows Services, but these sit around in memory, idle, eating 20MB or more memory per instance. Scheduled tasks will do their business, and release the memory immediately. What's the overhead of starting and quitting the app?
Every two minutes is pretty often. A service would probably let the system run more smoothly than executing your application so frequently. Both solutions can run the program when user isn't logged in, so no difference there. From a user's POV, I wonder which is easier to control. Both services and scheduled tasks are pretty much out of reach for most non-technical users, i.
The word 'serv'ice shares something in common with 'serv'er. It is expected to always be running, and 'serv'e. A task is a task. Role play. If I'm another operating system, application, or device and I call a service, I expect it to be running and I expect a response. If I os, app, dev just need to execute an isolated task, then I will execute a task, but if I expect to communicate, possibly two way communication, I want a service.
This has to do with the most effective way for two things to communicate, or a single thing that wants to execute a single task. Then there's the scheduling aspect. If you want something to run at a specific time, schedule.
If you don't know when you're going to need it, or need it "on the fly", service. My response is more philosophical in nature because this is very similar to how humans interact and work with another.
The more we understand the art of communication, and "entities" understand their role, the easier this decision becomes. All philosophy aside, when you are "rapidly prototyping", as my IT Dept often does, you do whatever you have to in order to make ends meet. Once the prototyping and proof of concept stuff is out of the way, usually in the early planning and discovering, you have to decide what's more reliable for long term sustainability. OK, so in conclusion, it's highly dependent on a lot of factors, but hopefully this has provided insight instead of confusion.
A Windows service doesn't need to have anyone logged in, and Windows has facilities for stopping, starting, and logging the service results.
Recently I was given a requirement to capture the screenshot of a radar from a Meteorological website and save it in the server every 10 minutes. This required me to use WebBrowser. I usually make windows services so I decided to make this one service too but it would keep crashing. Since the task was urgent and I had very less time to research and experiment, I decided to use a simple console application and triggered it as a task and it executed smoothly.
I really liked the article by Jon Galloway recommended in accepted answer by Mark Ransom. Recently passwords on the servers were changed without acknowledging me and all the services failed to execute since they could not logon. So ppl claiming in the article comments that this is a problem. I think windows services can face same problem Pls. Also the thing mentioned, if using task scheduler windows pop up or the console window pops up.
I have never faced that. It may pop up but it is at least very instantaneous. In the past I've put the 'core' bits in a library and wrapped a call to Whatever. GoGoGo in both a service as well as a console app. With something you're firing off every two minutes the odds are decent it's not doing much e.
The wrappers shouldn't have to contain much more than a single method call and some logging. So it should not be rocket science to switch from one to the other approach. In the past we used more or less always Windows Services but since also more and more of our customers switch to Azure step by step and the swap from a Console App deployed as a Scheduled Task to a WebJob in Azure is much easier than from a Windows Service, we focus on Scheduled Tasks for now.
If we run into limitations, we just ramp up the Windows Service project and call the same logic from there as long as customers are working OnPrem.. Windows services want more patience until it's done. It has a bit hard debug and install. It's faceless. If you need a task which must be done in every second, minute or hour, you should choice Windows Service.

In reply to KalinDimitrov's post on January 7, You would have to have two scheduled tasks if you want to do it this way.
In reply to Jacob Robertson's post on March 18, Don't worry - It is just another untested theory. Sick Freak says: If the service has a space in its name, like Print Spooler, make sure to put quotes around the service name.
First of all, there is no Service called "Print Spooler" - it is just "Spooler". If you change the user account or the program that is being run, you must supply the user account's password.
If the task program requires command-line options, type them in Run , after the task path. If the path to the task program includes spaces, type double quotation marks "" around the entire task path. For scheduled tasks that are no longer needed, you can remove them entirely. To remove a scheduled task Open Scheduled Tasks Right-click the task that you want to remove, and then click Delete. Removing a scheduled task only removes the task from the schedule.
The program file the task runs is not removed from the hard disk. To stop a scheduled task that is running Open Scheduled Tasks. Right-click the task that you want to stop, and then click End Task. If a scheduled task is started and then stopped, End Task does not stop all other programs that the scheduled task might have started. If you stop a scheduled task currently running, you might experience a delay up to three minutes before the task shuts down. To restart a stopped task, right-click the task, and then click Run.
On the Advanced menu, click Pause Task Scheduler. The Pause Task Scheduler command is useful if you do not want scheduled tasks to run at the same time as you are installing software or running another program such as a game. Tasks scheduled to run while Scheduled Tasks are paused are not run until their next scheduled time. To resume the schedules for all tasks, on the Advanced menu, click Continue Task Scheduler.
