Symantec Thursday released a free tool that wipes spurious entries from Windows' registry that had crippled some PCs running the company's security software after they were upgraded to Windows XP Service Pack 3 (SP3) or Vista SP1. The tool, SymRegFix, had been promised by Symantec two weeks ago when users reported that upgrading to XP SP3 emptied Windows' Device Manager, deleted network connections and packed the registry with thousands of bogus entries.
Symantec initially blamed Microsoft for the snafu, but later accepted some responsibility. Last week, the company said the combination of a Microsoft process and the SymProtect feature of its Norton-branded consumer security software had added the errant registry entries, and it told users to turn off that feature before upgrading. Symantec's SymRegFix clean-up tool can be downloaded from the company's site.
