Windows 11 installation failing with an '0x8007007f' error? There's a workaround
Microsoft started to roll out Windows 11 yesterday -- a day earlier than originally stated -- and many users chose to immediately jump on the new OS, installing it via either the Media Creation Tool or the Windows 11 Installation Assistant. The latter is the method I used to painlessly upgrade both my desktop and laptop PCs.
For some users however, the process has been far from painless, with a number of eager upgraders reporting the installation stalling with error code '0x8007007f', despite their having compatible hardware.
