My fully patched Windows 10 laptop has been trying to install a FILR update since last evening through several attempts. It appears to jump very quickly through the installation and then gets to "Validating Install." The Progress bar drives smoothly over to about the 80% mark and then freezes. Eventually, I get a message that the installer is no longer working. Retry repeats the above exercise. Tried rebooting to clear anything lurking under the hood, same scenario. Any thoughts?
