Method Three: Download an Automated Tool
If you wish to always have at your disposal a utility tool to fix these Windows 8 and other related issues when they do arise, download and install a powerful automated tool.

The game mode is active at all times and usually, everything works great but in some instances, it can sadly cause some performance issues. If you are one of these unlucky people where game mode is not working as supposed to do, don’t panic, we have a quick guide for you on how to turn it off.
EVE Online is one of the earliest MMO games out there but since its release, it is still actively developed and is receiving updates. This science-fiction Sandbox will offer space lovers everything they need and more. Large scale PvP, mining, pirating, etc. It can be daunting and complex for beginners but take your time to get familiar with its systems and you will be rewarded greatly with an immersive and complex game worth the time. Open PvP in some zones might not be everyone’s cup of tea and seeing only your ship might be a turn-off for some players, but if you do not mind these things give it a go. It is free to play with an item shop.
FF14 had a tough start, so tough that it was scrapped and destroyed and has been remade again and that idea was great. The game now is better than ever and at this time it is experiencing large players from other games surging into it. This on the rails fantasy MMO will offer you a great story and great leveling experience. It has a free trial where you can play the whole original game for free but if you wish to continue playing you will have to buy the expansion and pay a monthly subscription but the content is well worth the money.
Let’s be honest, not a single list of MMO games cannot be without a once greatest and most successful MMO ever made, World of Warcraft. But instead of me praising the game why it was the greatest and why you should play it and how great it is I am going to take a little different approach. I am going to recommend you World of Warcraft classic, yup, you read it correctly, classic. Now World of Warcraft is a retail game with a subscription service but with that one subscription you will be able to access three games in the World of Warcraft universe: World of Warcraft retail (standard game), World of Warcraft Classic (vanilla WOW without expansions offering you experience as it once was when it was released) and World of Warcraft the Burning Crusade classic (same as WOW classic but with the first expansion the Burning Crusade). Among all solutions, I would really urge you to play either WOW classic or WOW TBC classic simply for reason that they are far superior games in comparison to typical retail ones, but if you like easier game go for retail, it is included in the sub anyway.
Guild Wars 1 was one of my favorite games and I sank a lot of times in it and once Guild Wars 2 came I must admit I was pleasantly surprised with it and I would recommend it highly. The base game is completely free to play with only expansion to be purchased and it is buy to play model without monthly fees. It has specific mechanics different from other games and interesting classes to try. The living world is a great feature of the game and it is still very strong with its player base.
This game is made for people who enjoy, love, and like Star Wars. Mechanically besides being able to have henchmen with you and space battles (which I do not really like how they are done) game itself does not offer anything special. Where it shines is in the story and overall Star Wars experience. If you look at this game as a single-player game with multiplayer dungeons you will have a great time, since the story is really good but sadly end game lacks in comparison.
I am going to admit something here, I was not fond of the idea to make the beloved Elder Scrolls series into MMO, but in time I gave it a go and I am really glad I did. This game is great and it is getting better and better as time progresses. It is buy to play without monthly fees and basic game free, same as FF14 but without fees. It has a decent community and offers a really good Elder Scrolls experience and now it is packing Morrowind expansions and other great areas. Highly recommended for any Elder Scrolls fan.
This one is troublesome to recommend, on one side you have free to play games deeply inside Tolkien Lord of the Rings lore, on the other side, you have outdated graphics and some stupid item shop decisions like buys specific classes. But if you look past stupid item shop decisions and can live with playing free class in the game you will be pleasantly surprised. The game itself is surprisingly good, the story is great as expected from the game infused with lore taken from one of the best books series ever written, and the feeling when visiting iconic landscape is epic. But if I need to be real as I should, I would recommend this one to people appreciate good story and lore and ones that are fans of Lord of the Rings itself.
Neverwinter is a premium and licensed D&D MMO game and it is well strange. The free-to-play model of the game will let you enjoy it until you hit the end game, then you will have to shell real money if you want to be competitive but the journey until then is great. I would recommend it to D&D lovers and people that love to try other people's maps, yup you read it correctly. Neverwinter has a map editor making it one of a kind MMO game where you can create your own dungeons and post them for other players to play, this user-generated content makes it a very specific beast in this list, and for that feature alone it has my recommendation.
Another one of the older titles, Tera will offer you nor depth nor anything new in terms of leveling, quests, or end game except… the COMBAT. This is maybe the greatest MMO Combat game ever created and it is quite fascinating that even after so many years no other game has managed to create a better combat system than one of Tera. If you enjoy action combat and like some specific aesthetics Tera is a game for you.
Albion is a sandbox game with open-world PvP and building mechanics where you can build your own forest, house, etc. You know, sandbox stuff, including a lot of crafting and well, other sandbox stuff. If you want great quests and some occasional play then skip Albion, this game is made for a more hardcore player base not being afraid to die and spend some time crafting and going through the economy. The best comparison might be with EVE but in fantasy settings.
Black Desert is also a sandbox game but different from Albion, here you can organize and hire a workforce and send them to different nodes on a map to harvest resources and build an economy while you are on some epic adventure. Housing is also included but you can buy already made houses instead of making your own in the world. Combat is a game that comes very close to Tera combat and it is very enjoyable. The end game is money sink and PvP based so be careful when choosing this one.
If you like occult and supernatural with new world order themes and conspiracy theories, Secret World Legends is the game for you. Somewhat little clunky its setting and story really set it apart in many many ways. It has semi-action combat and it is free to play with item shop but all the content can be experienced for free. Recommended for fans of deeper gameplay and horror lore.
When I said no MMO list can be without World of Warcraft, it also cannot be without Runescape, one of the oldest games it was revamped with newer mechanics and graphics, free to play all the way and you can also pick old school Runescape if you really want to go all the way on a nostalgia trip. I would recommend a newer one for newer players, the game offers a great story and unusual quests infused with puzzles and interesting storylines. If you like really good quest design without fetch and grind quests along with interesting story this is a game for you.
Last on my list would be AION, a very interesting game made also a long way back, but the fact that is completely free with the cosmetic shop will make it as one to recommend since you can experience the whole game for free. It has some limited flying mechanics in it and later game zone are open PvP zones, story is interesting and leveling process is enjoyable. Also game itself is not really easy and if not careful you can get yourself in danger quite quickly. Recommended for old-school feeling.
Bluetooth perhaps is slowly becoming an outdated feature but sometimes you can really used it and need it.
By default, in Windows 11 Bluetooth is turned OFF so if you need it, you will need to turn it ON first. Luckily turning it ON is easy and we will guide you through the process
