Microsoft customers have been plagued with problems that have foiled attempts to install the Windows 8.1 update, according to widespread reports on the company's support forums.



From Computerworld:

While the situation on traditional PCs and Windows 8-powered tablets has not prompted Microsoft to yank the update -- as it did Friday with the one designed for Windows RT -- they have frustrated users' efforts and gotten a few angry enough to swear off Windows 8.1.

Customers saw a variety of cryptic error messages, but most reports about the sequence of events were similar: After the update has downloaded and was being installed, at some point the PC or tablet spontaneously restarted with an error message. The update then tried to recover but failed a second time -- or went through that cycle several times -- before restoring the system to Windows 8.
