The Anniversary update has been a disaster for me. I'm running three laptops with Windows 10 and am having the same problem on all three:
Live tiles on MSN News, MSN Money, Flipboard, Facebook, Twitter, Messenger and Ouga, etc do not update, or update rarely. Running the Windows Apps troubleshooter, I get a message saying the Windows Store cache may be damaged. Following reset by the troubleshooter, it claims to have fixed the problem.
I have contacted MS Customer Support a few times about it, and each time I've been told that if doing the "restorehealth" under Powershell and "sfc /scannow" and "wsreset" under the Command line don't work, I should do an "in place" upgrade. I have done the upgrade, but the problem remains. The cache is always damaged and the live tiles don't update: they either freeze or go blank. I have even re-downloaded the app packages, but this makes no difference.
Since the problem is the same on three laptops - two HP ProBooks and one Acer - it obviously isn't a problem with a corrupt profile.
One support technician told me it was a known issue and that an update would be done by MS. The Store updated a few days ago, but there is no difference. The other two technicians I dealt with had never heard of the problem and had no idea how to fix it, except by telling me to do the in place upgrade from the Windows 10 page.
Some practical advice on this would be great, because it's driving me up the wall.
