We are currently experiencing severe Windows 10 issues. The best solution is to downgrade to Windows 8.1 which will require re-formatting the hard drive. The catalog is on the E drive, which I can disconnect and protect. My concern is re-connecting LR to the catalog and actions after re-installing. Is there a way to save the settings on the cloud and import them after I re-install LR? The last time I had to re-install LR it took me forever to re-establish all of the settings and links. Thanks in advance!
