You can change ownership manually, on your screenshot, click on Change and add your username, then check and OK.
Or you can delete it, it seems like a leftover from WinUpdates, though 300GB is a bit excessive, unless you use Insider.

All this suggests that your G:\ partition might have got corrupted at some point. Have you tried a disk error check?
That's a lot of data.
Before deleting it, you might want know what's in it.
My first guess is a backup (File History on?)
I like to use Linux Mint in situations such as this:
Download - Linux Mint
I use the Mate edition, but other folks like Cinnamon
Boot to the Linux thumbdrive
take a peek at what 's in the folder
Then it's your decision to leave it alone or remove it.
I'd leave it alone until I knew exactly what is is and why it's there.
You probably already figured this this out, but you can delete files and folders from Linux as well.
Thank you guys for helping me out
