Many of the apps and folders in my Windows 10 Start Menu appear "grayed-out" and I don't know why (see screenshot below).
Some of the apps are from the Windows Store. When I open them, I sometimes (but not always) get an error message that says the app can't open (pictured below). Reinstalling the app from the Store usually fixes this issue. But this only happens with some of the Windows Store apps. Sometimes, they are grayed-out and they open just fine.
Not all of the grayed-out apps are Windows Store apps. Some are just regular Windows programs (for example, "Access 2016" in the screenshot above). Also, some of the folders are grayed-out too (for example, "7-Zip" in the screenshot above). I can still click on them and launch them if they are grayed-out. They are just colored gray instead of the usual white.
The items that it chooses to gray-out seem to increase throughout the day. When I first boot the computer up, all of the items look normal. For example, this morning, after about an hour, half of the items were grayed-out. Restarting Windows Explorer fixes the problem temporarily, but soon after, the items start to turn gray again.
I've tried the solutions here and here, but they didn't work for me. Most of the sites I've visited seem to be focused on fixing the Windows Store apps in particular, and don't address the broader issue of random items being grayed out.
Some sites suggested doing a Windows reinstall of some sort, but that seems like overkill (and it may not solve the root cause).
This occurs on all user accounts on my computer.
I tried updating my video card drivers, but that had no effect.
My computer is a few months old and came with Windows 10 pre-installed.
I'm running Windows 10 Pro version 1703 (OS Build 15063.540)
