My dual boot system (W7 / XP) is working ok but booting into XP cleared the W7 Restore Points. I applied the recommended fix (to XP's registry) and that cleared the problem so I now have W7 Restore Points again. However, the fix seems to have caused W7 to no longer go into 'sleep' mode: it worked before but now it doesn't. I reversed the procedure (rolled back XP to before the fix) lost my W7 restores but still can't get it of sleep. Has anyone else experienced this, and fixed it?
