The other day I was trying to install Windows XP SP2 on a computer that had SP1 installed. I’m not sure how it got to SP1 (upgrade from XP, upgrade from Win98, etc), but I kept getting to a certain point that was telling me “Access Denied”. As I researched this it turns out it was a permissions error in the registry. The suggested answer was to reset permissions on 4 registry keys, but as I looked around the registry, there were all sorts of permissions that were wrong. I’m not sure what happened, but I did figure out how to reset the permissions back the default.<\/p>\n

“Access Denied” error when trying to install SP2<\/a>
\nThis article explained how to use the SubInACL utility from Microsoft<\/a> to set the permissions on certain registry hives. I guess this doesn’t specifically set them back to the default, but it allows you to set hives or keys to what you want the permissions to be.<\/p>\n

How to reset security settings back to the defaults<\/a>
\nThis Microsoft Knowledgebase article does explain how to reset the permission to the default. It uses a utility that is included with Windows XP so it is very easy to use.<\/p><\/blockquote>\n

Remember, this tip isn’t just in case SP2 won’t install. If you have been messing around with the registry and changed permissions, this is a way to get them back to the default. And of course remember… when you are working with the registry, be sure you have a backup in case you do something wrong.<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
