BUG in feature update to windows 10 version 1909 via enablement package (KB4517245)

So far the fix for 2 of my co-workers machine was to rebuild the index. It's only been a few days but they haven't told me its broke again.

Control Panel

View Small or Large icons to see the entire list.

Indexing Options

Click Advanced

Click Rebuild.

Click Ok

Click close on the indexing window once the rebuild is complete.

Hope this helps others

we don't understand this from the very first sentence. What control panel do you speak? somewhere with file explorer or back within windows OS? We can't follow any of this as 'indexing option' where is this? Rebuild...where is this? have let several people look at this and they couldn't help either.

You can find the Control Panel by hitting Start and typing "Control Panel" (without the quotes.) Click on the Control Panel result to open it. Then follow the rest of the above instructions. You can either rebuild the indexes or modify them to ensure they don't contain invalid entries, as described here. Remember to reboot the PC once either the rebuild or the modification (whichever you choose) is complete.

Click on your start menu and start typing the word Control and you should see Control Panel show up as an option to click on and view. Its the old school control panel back from windows XP days. Or you can open file explorer and in the path area type Control Panel and it will open that way. A shortcut to the indexing option itself is when you click the start menu start typing Indexing and you will see  Indexing Options with control panel in small lettering under it. When I say click the start menu, bottom left click it, when it opens with the list of apps and such just start typing on your keyboard and it does a search. If you are one that has the big search bar in your taskbar then you can click in there and start typing. Hope this helps.

With all that being said. One of my coworkers came to me a few hours ago and said this fix lasted about 4 business days for him and it broke again. So he is going to rebuild it again and see how it goes. He only has the issue when trying to open a file in an Adobe product like photoshop or illustrator when using the top right area to search for a specific file in a folder.

Not sure if folks are missing this or not, but I keep repeating it: You'll most likely also have to modify the indexing options to ensure only valid locations are being indexed. I think the update changed some of the storage location unique IDs and so indexing is being attempted for locations that no longer exist (kind of like FedEx trying to deliver to an address that now has a new street name.) I'm not sure rebuilding by itself fixes the problem, but I know for sure in my case that unchecking all the indexed locations and rechecking only the valid ones (the UI will tell you if a location in invalid on mouseover) fixed it permanently for me.

We just did the unselect everything method you posted and reselected the items in the list from clicking modify. Uncheck the boxes. Close out. Modify again. Click show all locations. Recheck everything but C drive one. Restarted the PC. It is currently working but only time will tell over the next few business days if it breaks again.

Fingers crossed! Only 1 of my 5 Windows 10 1909+ machines had this problem, and this fixed it for good. Cheers!
