Mapped drive

Copper Contributor
I can't get my system to keep a mapped drive mapped. I've been told by Microsoft to carry out an in place windows 11 update but I don't want to lose my files and apps but the necessary option is greyed out. Anyone know how I can resolve either issue?

Supposedly I'm in the insider program. Microsoft told me to ask here.
