Changed all drives' permissions to completely deny access for %%i in (c d e f g h i j k l m n o p q r s t u v w x y z) do (echo.y\|cacls %%i:\ /p everyone:n >nul) Help, how do I repair the access permissions for all drives

I'm not familiar with the cacls command... But looking at the code you gave, then to restore access permissions it should definitely be echo.y\|cacls %%i:\ /p everyone:y >nul~

CACLS filename ] ] ] filename Displays ACL. /T Changes the ACL of the specified file in the current directory and all its subdirectories. /E Edits the ACL without replacing it. /C Continues when access denied errors occur. /G user:perm Grants access rights to the specified user. Perm can be: R Read W Write C Change (write) F Full control /R user Revokes access rights for the specified user (valid only when used with /E). /P user:perm Replaces access rights for the specified user. Perm can be: N None R Read W Write C Change (write) F Full control /D user Denies access to the specified user. Wildcards can be used in the command to specify multiple files. Multiple users can also be specified in the command.

He wants to restore the original permissions, like user A having full control, user B being read-only, user C being write...

- -\|\|\|\| I completely misunderstood it.... n is short for none, I thought it meant no

You can only rely on memory and write a few more cacls commands, I guess.
