Good morning

Yes, you can get the Xbox PC Game Pass for 3 months again through Microsoft Rewards after your subscription is over.

Join the Microsoft Rewards Program and you can use your rewards for Xbox Live and Game Pass subscriptions. I haven't paid for Xbox Live in years. I just keep getting my rewards and redeeming Game Pass Ultimate 3 month codes.

Is there a limit to how many times you can get it?

you can get free Xbox Live Gold/Game Pass by signing up for Microsoft Rewards.

https://account.microsoft.com/rewards/

you can earn points just by using Edge browser and Bing search engine on PC and by using Bing search on your phone.

there are also more ways to earn reward points on Xbox by downloading the MS Rewards app.

if you have Game Pass then there are also Game Pass Reward Quests where you can earn reward points just for playing games.

I've found that by upgrading my subscription to Game Pass Ultimate then topping up with 3 months of Gold or Game Pass from MS Rewards is the best value (3 months of Gold gives 50 days of Game Pass Ultimate, 3 months of Game Pass gives 60 days of Ultimate
for the same amount of points as 1 month of Ultimate)

I noticed that you said your friend couldn't play Roblox on your Xbox even though you own it.

have you set your Xbox as your Home Xbox?

if it is set as your Home Xbox, anyone who signs in with their own account will be able to play any of your games and also make use of your Live Gold/Game Pass.

here is a link with everything you need to know about setting your Xbox as your Home Xbox.

You can get Ultimate Game Pass for $1 right now in some regions. It includes Xbox live, Game Pass for console, and Game Pass for PC. Even if you don't use the Game Pass for PC it is worth getting for a $1 to get Xbox Live and Game Pass for 3 months.
