You may not necessarily have to use linux but historically Zcash windows native programs are iffy. If running as an admin still fails then you could try importing keys into a windows
version of zecwallet lite GUI or CLI or a Ywallet, also as admin. If your heart is set on the full node you should (may) be able to run zcashd in WLS2 inside your win10 as well most any other linux Zcash CL tool. You could also try running zcashd from CL (power shell or equivalent) to try to catch up and then restart with the GUI. Ill have to look up that dir, ant remember off top of my head.
