Step 2: Clean Up Windows 10 Startup

Launch Task Manager and then click the startup tab. You need to disable any unneeded programs from here.

Changing Startup Programs (Advanced Users)

You can change startup programs from Start – Run – shell:startup and Start – Run – shell:common startup

You can also modify startup programs using registry editor HKCU or HKLM\Software\Microsoft\Windows\CurrrentVersion\Run

Cleanup Task Scheduler, as it accumulates many things that cause an install to be slow and is vital when you clean up Windows 10.

Step 3: System Tweaks and Privacy

There is literally hundreds of settings in Windows 10 that are privacy concerns and why I’d recommend using a 3rd party software for this. However, you can do all the same tweaks by simply going through settings and doing all these manually. That said, I recommend using O&O Shutup10 for optimal tweaks and privacy.
