I'm now running x64 xp because theres some serious issues with x64 vista file copying taking forever even timing out. Is there any returnil, shadow defender, keyscrambler equivalent for x64? Rollback Rx works on x64. vista memory problem The problem can be clearly seen when a user tries to copy 16,400 files or smaller groups of files that add up to 16,400 between reboots.After you get the 'Out of Cheese' message you will also suffer from menus and tabs disappearing within the Windows environment and even reboots and BSODs are reported.The problem occurs where users are running Kaspersky security products, but it is not the software that is causing the problem. Other software also suffers but it seems that the Kaspersky software shows the error in its full glory.
