I'm currently reorganising several thousand photos, and use the 'tags' feature in Windows Explorer a lot. On my old laptop (Windows 8), I used the autocomplete / tag suggestions, in which previous tags are shown in a drop down list as I type - this saved a lot of time for me. However, on this computer (Windows 10) it seems to be incomplete - some tags are showing up in the drop down list, but ones I know I've used are not showing up. The missing tags include ones I entered weeks ago, with many restarts since then. The tags are still present on the files to which they were added and the files do correctly show up in search results when searching for those tags, but I still can't get the tags to show up in the suggestions. I've tried changing settings to allow the contents of the folder to be indexed, but this hasn't made a difference. I've also tried rebuilding the search index, again this didn't help. I've searched online looking for a solution, but haven't found anyone with this problem.
What should I do in order to get the autocomplete tag suggestions to refresh or update to show the missing tags? Or is there a setting I should change?
