Windows XP won't store any registry values

Posted on 2006-04-12

A PC got incrediby low on disk space.  After restarting, all settings were lost so no desktop wallpaer, can't save one, can't customize the Start Menu using START |PROPERTIES.  MS Office won't run.  Registry looks OK in visual examination.

Ran sfc and it is OK.

When installing a program, I get Error Creasting Registry Key, Access Is Denied.  RegCreateKeyEx failed: code 5

Any advice other than a complete XP reinstall?

    Probably the best thing would be to reinstall.

    you will spend more time fixing up your OS than a FRESH spanking brand new install.  Just backup your files.

    i would try to get more space first, and see if that somehow cures your problem.
    you can delete in IE all temp files and folders
    search for temp or tmp files and folders, and delete them
    uninstall old and unnecessary software
    how much space do you have left?
    backup what you can and delete it from the disk.
    Then run a disk scan for errors on it, and a defragmentation

    I solved the problem by changing the Permissions inside the registry.  Somehow, the Administrator permissions were shut off.  I gave full control and everything is now fine.
