yes please, but in database optimization, Ken is recommended for consultation, do ask for his input. Also as you mentioned cron hasnt been running, do a manual cron run.

Michael, you've got one thing right, XAMPP is not for production, XAMPP is usually used when base operating system doesnt comes with a web server of its own (Windows Home editions) so developers can use XAMPP to develop web applications.
anyway, now you have to dig in history, 150 concurrent users isnt very resource demanding but there are plenty of factors playing the role to degrade the service overtime. so you have to find out, what was the initial moodle version installed? as it must have been upgraded overtime and every major moodle update comes with added features at the cost of hardware resource.
secondly, was the test questions remained the same throughout? as they must be changed on yearly, semi-annually basis, this adds to the calls to database.
thirdly, what kind of VM is your Windows server hosted on? as VM's (unless a true hypervisor is used) adds a layer of host operating system beneath, this adds to latency, therefore a direct hardware install is always better than a VM.
Leon already have mentioned 32-Bit, and its limitations of using RAM (3.5GB it is), but have you as well tried allocating more RAM resources to your DB? rather than just allocating to VM?
Lastly, using IIS would be best option, as you will be able to run same tests on same hardware, as sometime ago I had this scenario came up where moodle was setup on XAMPP and though was working, but very slow, so I switched it to IIS on weekend night, and first mail I was sent by the teacher in morning was from student saying what a speed difference, and its been 2 years, no complaints of speed or system getting down ever since.
my advice, switch to IIS and things will improve very very likely.
Issa, your local ISP must have issue, else site loads fine. you should have tried hosting locally if your audience is local. your use of images is not optimized for web transfer (very heavy). try optimizing images and see if things improve for you.
WordPress is a content management system, while Moodle is a learning management system, whilst wordpress can be used for developing a simple/basic learning management system, but if you want a full functionality of a purposely built learning management system, then moodle remains the only choice.
rest, whatever you require to run wordpress, you'll need same things to run moodle as well, in addition a slightly more capable web server (pointing to a being full fledged learning management system, requires more horse power).
you can always start with documentation https://docs.moodle.org/36/en/Main_page and first section you'll see, mentioned Get Started (document writers gets credit in making things simpler to understand now).
should any queries, that are not addressed in documentation comes around, forums are best to ask!
Good luck starting with moodle!
Wayne, when you say other videos, what is the source of those working videos?
Privacy Badger tends to bread the websites quite often, not that I personally use it but there must be settings to ignore heuristics from a certain website.
