Restore default registry permissions

[redcat]

Hi everybody, I'm not sure what messed up my registry keys but the administrators users can't open them anymore on my Windows 7 machine. So I'd like a method that reset them to the default settings.
I found one way, which would be to set everything with Administrators full control, but that is hardly the default... what about SYSTEM and Users?
I'm not sure I can try a repair installation, as I only have the Windows Vista to 7 upgrade dvd...

Thanks

I found this on another site. It may or may not fix your problem


First you need to download SubInACL from here SubInACL is a command-line tool that enables administrators to obtain[FONT=inherit !important] security [/FONT]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 you need to open command prompt run the following command
cdcd “C:\Program Files\Windows Resource Kits\Tools”
after this press enter and enter the following command
reset.cmd
after entering this please press enter
after a few minutes by processing subinacl, the permission will be reset

You can run system restore to a point before all the trouble started, that'll restore the registry as well.

As for permissions, you can change them for whichever key you want. Heres an illustration.

Full Control Permission to Delete or Edit Restricted Windows Registry | Raymond.CC Blog

A backup of various registry hives is stored in the folder C:\windows\system32\config\regback. Check the date, if it pre-dates the troubles, you can boot from the win7 dvd, navigate to the command prompt, then rename each of the hives in c:\windows\system32\config to .old or .bak extension, then copy the backed up hives in the regback folder to the config folder. Restart the computer.

Thanks but subinacl isn't available for windows 7, and I don't think all keys just need Administrators and System full permissions. There are other users too.

No, the dates are too close.

Is there a way to make a bat file to do all of it automatically? and if so how ?

Thanks for any help in advance ..yes I know that this is an old post but I am hopeful that someone could help me
