74-second boot: who is slowing it down?

Not a count of startup apps, but the delay Windows itself measured. You get names and seconds, like "Adobe CC: 8.2 s on average, 4 times".

What it does

Collects boot performance events and calculates the average delay per app, service and driver.

Disables them the same way Windows Task Manager does, and you can undo anytime.

Finds scheduled tasks that aren't in the Startup apps list, and disables them after you confirm.

Re-measures boot time after a restart and records how many seconds you saved.

Will it disable my antivirus?

No. It never suggests disabling antivirus, drivers or Windows components, and blocks it even if you ask.

It got slower after an update.

Update impact analysis compares boot time before and after the install and lists it as a likely cause.

After installing, click the tray icon and your first diagnosis is already done. Every change runs only after you confirm it, and can be undone.
