Resetting the entire registry permission

There will be times when you either:

1) Have some sort of malware running on your machine

2) Accidentally changed the permissions of your registry

and needed to reset the registry permissions to default. 

Here’s how:

download SubInACL from here

SubInACL is a command-line tool that enables administrators to obtain security information about files, registry keys, and services, and transfer this information from user to user, from local or global group to group, and from domain to domain.

Create a file with the name reset.cmd under C:\Program Files\Windows Resource Kits\Tools folder

Now you need to Edit the reset.cmd file and add the following lines

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f

subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=system=f

Save and exit your file

Now launch command prompt and run the following command

cd “C:\Program Files\Windows Resource Kits\Tools”

after this press enter and enter the following command

reset.cmd

after entering this press Enter

After a few minutes by processing subinacl, the permission will be reset
