task scheduler can be safely disabled?

it contains a lot of useless tasks (eg. those involving telemetry)

and if I'm not mistaken the ONLY useful (ie. performance-improving) task is the scheduled defragmentation right?
and this I can remind myself to do regularly

besides if defrag is scheduled to run at a certain time regularly by the scheduler, what happens if that time happens to be the time I'm playing a game? then the scheduler will defrag while I'm playing & this will obviously destroy gaming performance (not to mention make it hard for defrag to properly do its job) so more of a reason to disable auto defrag right?


ps. I don't auto-update anymore so I don't need scheduler for that one either

I myself have disabled many tasks but didn't disabled any system task.
If you want performance you should install a small SSD (128G) for Windows and programs and use the HDD for data.
As you don't defrag SSDs, the HDD defrag won't affect your game.

To get rid of telemetry, use spybot-anti-beacon
Spybot Anti-Beacon for Windows

Can the Task Scheduler service be safely disabled?

NO.

The Task Scheduler was first introduced in Windows 2000. It was available for user and application use but Windows did not use it. That changed in XP. In later versions of Windows it is used extensively by the system and by third party applications as well. Not all of these uses are fully documented, if at all.

In Windows 7 the Task Scheduler service cannot be disabled by normal methods but it can be done in the registry. I will not describe how. Do this and you are in uncharted territory. You can expect that some things will not work and others may behave strangely.

In the real world things have a tendency to break when forced. In Windows 7 the Task Scheduler service cannot be disabled by normal methods. This is a less than subtle sign that you should not do so. If forced by using the registry things will break. In this case "break" can mean a variety of things but some will be unpleasant.

I saw on another forum where a user tried this. There were some unanticipated results.

alrite so lemme put it this way: without disabling task scheduler itself :

what are all the necessary tasks that should not be deleted?
(or, what are all the tasks that can be deleted?)


bt(w I checked out the spybot thing but the last version appears to be 2 years old - who's to say M$ hasn't added sh*tloads of extra telemetry in their later updates? will spybot detect the newer telemetry as well? (like an anti-telemetry heuristic or something)
