I originally only included this in the readme of Windows 7 Updated v4, but I figure I might as well make a post for it. I also have found new tasks to remove that aren't in that readme, so even more reason.
This post will go over tasks in Windows 7 that you can disable or delete for more performance, privacy, and security. This list is based off of the upcoming Windows 7 Updated v5. (Link here when finished) Windows 8 and 10 have more tasks to disable or delete, lists for those will come soon.
There is nothing that I know of that would allow for batch applying these. I think you can only manually apply these.

To open Task Scheduler, press the windows key, type taskschd.msc, and press enter. Go under Microsoft > Windows and delete these tasks:
Application Experience - All
Telemetry.
Autochk - All
Telemetry.
Customer Experience Improvement Program - All
Telemetry.
Diagnosis - Scheduled
This seems to be telemetry, but I'm not too sure since it could just be periodic maintenance. Maybe disable just in case?
Disk Diagnostic - Microsoft-Windows-DiskDiagnosticDataCollector
Telemetry.
Location - Notifications
Location tracking.
Maintenance - WinSAT
Annoying and useless. Can just randomly start in the background and cause issues with applications (especially games) if you happen to be using them at the time it runs.
Media Center - All
You might want to just disable everything instead just in case it breaks something in Media Center. Disabling Media Center
from Turn Windows features on or off removes all of these.
NetTrace - GatherNetworkInfo
Telemetry.
Power Efficiency Diagnostics - AnalyzeSystem
This seems to be telemetry, but I'm not too sure since it could help with power consumption. Maybe disable just in case?
RemoteAssistance - RemoteAssistanceTask
It looks useless and Blackbird recommends disabling it.
Setup - EOSNotify & EOSNotify2
Windows 7 end of support nagging.
Time Synchronization - SynchronizeTime
Optional, you might want this if you care about accurate time and don't block the NTP port (123).
UPnP - UPnPHostConfig
Seems to be for enabling the UPnP service if the user disables it, doesn't need to run even if you don't disable it.
Windows Error Reporting - QueueReporting
Telemetry.
