XP Registry security reset utilityLocked
PC with 60 viruses & 800+ malware machine cleaned but in the process “lost” the security settings for lots of registry keys. I amd trying to install SP3 but it errors when trying to backup the registry with “access denied”. I can reset the security on an individual key by taking ownership the applying full access to admin. Have done this to about 100 keys so far. Tell SP3 to retry it then gives you the next problem key. Is there a utility that can do this? non of the registry cleaners I have tried check the security. I have tried ccleaner, registry mechanic, malwarebytes reg assassin (tried to delete a registry key and it could not do it – access denied). Any suggestions?
