ummm......yeah....that's not it.
Running Windows 8 Pro 64-bit (Upgrade from Win 7 Home 64-Bit) on an ASUS K55N Laptop.
Have tried many things and even disabled all startup services except for Microsoft only items and continually get this error code....as well as downloads that stop and restart all the time instead of working.
Researching this issue.......it seems Microsoft has a dud on their hand as this issue is occurring for alot of people.
FIX IT MICROSOFT!!!
Please release a standalone installer for 8.1 (that uses our existing Windows 8 Keys) or just release a standalone 8.1 Patch installer..........Using the STORE to rollout the 8.1 Update is a HUGE Mistake.
