Another Solution for Error 0x80070005

Hi everyone,

For all those of you who try to fix that error 0x80070005: If all hints
available here and on the web do not help and if you have turned on file
encryption, check your C:\WINDOWS\system32\CatRoot directory and all files
and folders within it. If something there is encrypted, then this is
certainly a cause for error 0x80070005, as then the SYSTEM account is no
longer able to read from the .cat files.

I figured out that if one uses file encryption it now and then happens that
some of the .cat files end up encrypted in the CatRoot. This probably
happens when something new is installed from encrypted setup files. I made
myself a batch file with the following command that I always run as soon as
Windows Update fails with error 0x80070005:

CIPHER /D /A /S:"C:\WINDOWS\system32\CatRoot"

Good luck,
Juerg

CIPHER /D /A /S:"C:\WINDOWS\system32\CatRoot"

Not to denigrate this useful post Juerg, but perhaps you'd care to
explain what the command does to the CatRoot directory that's been
encrypted or, > when something new is installed from encrypted setup files

Generally speaking, 0x80070005 means Access Denied .

Well, the command decrypts the directory (see "cipher /? | more" for more).
If it is encrypted, then the Local System account (under which Automatic
Updates runs) can no longer access the files, as the key to decrypt the
files belongs to a user account and not to the Local System account...
