Rails db:migrate:reset producing Errno::EACCES Permission denied @unlink_internal

I am following the Rails Tutorial by Michael Hartl, and at certain points we are to run
rails db:migrate:reset
However each time I do try to do so I am faced with a permission denied error concerning the file

development.sqlite3

I have tried the following solutions I've encountered:
1. close all programs suspected of using said file and retry task
2. terminate rails console, server, editor and retry task
3. shut/restart pc and executing the task upon restart
4. executing rails db:drop

All of which have failed to allow the command to run. The only working solution is to delete the file manually and running rails db:migrate

I am running

Rails 5.0.0.1
Ruby 2.2.5p319
Sqlite3 3.14.1
Windows 10 Professional

My stack trace is:

** Invoke db:migrate:reset (first_time)
** Invoke db:drop (first_time)
** Invoke db:load_config (first_time)

Tasks: TOP => db:drop:_unsafe

How can I remove this error and prevent it for future projects?

Just don't use Windows for the development! – Aleksey
There are a ton of similar questions on Stack Overflow, like this one. Remember to search first. And honestly, Aleksey sounds flippant, but he's right. Install Vagrant or something like that and run a virtual instance of linux and develop in that instead of Windows. – MarsAtomic

I get the same error using Windows 10 Pro | ruby 2.4.1 | Rails 5.1.4. I soved using:

rake db:drop:_unsafe
rake db:create
rake db:migrate

I had the same issue with this command following the steps in the book on Windows 10, Ruby 2.6.0, Rails 5.2.2. I was also using DB Browser for SQLite with that database as well.

After I closed the Browser, rails server, and everything else that was still using the database, I still received the error, even after a reboot.

In order to resolve the issue, I had to delete the development.sqlite3 file manually via Windows and then do a rails db:migrate
