Hello Sigma,
If you like as a test, this has been reported to help others with this not refreshing issue sometimes.
Use step 4 in OPTION ONE of the tutorial below to show hidden protected OS files.
Hidden Files and Folders - Show or Hide
In all of the affected folder locations that do not refresh, delete any faded
desktop.ini file(s) in those locations.
Restart the computer to apply and to have new default desktop.ini files created for those locations.
Use step 5 in OPTION ONE of the tutorial above to hide the hidden protected OS files again.
Hope this helps,
Shawn
