Being an insider, I got the creators update sooner than I hope it to come. Not a bad thing actually. Due to this insider update, I am able to encounter a problem and share with you how to fix it.
So I use an Arc Touch Bluetooth mouse. When the update came, I didn't expect my mouse to stop working. So all of a sudden, it failed and I tried so hard to figure out where went wrong. I thought it might be my bluetooth driver went busted or something. But turned out that after a reinstall, my mouse still ain't working. Strange thing is that my mouse is still connected to my computer via bluetooth. I reboot countless times over, reconnected countless times over, searched around forums, still could not get any answers. I was almost at the brink of reformating my computer just so I can get my favourite mouse to work.
Bingo, I got it to work. So here's how you get it to work after you install Creators Update.
You might need to get another working USB mouse while you fix this issue.
