Extend roll back time

[Babs3]

I've just installed Win 11 and understand I've only got 10 days appraisement time. I've read somewhere that the command
DISM /Online /Set-OSUninstallWindow /Value:60 will extend it to 60 days. Is this correct? I'm not sure of the spacing after some of the text in the command?

Thanks

Make an image of Windows 10 with something like Macrium. You can then return to it at any time.
Do the same with 11.
I have both 11 and 10 in a dual boot.
