Hi, sorry i wasn't able to get back to you as quick as you got back to me Shane.First i just want to tell you i bought the 3 disks for my Asus Essentio Desktop cm 1730-01 . I'm running Windows 7 sp1 64 bit. I think my worst problem now is When i run sfc /scannow and system checker The scan only runs in read mode because it says F parameter not specified on system checker read mode only.So i don't believe anything i do in windows now will fix.I've run Diagnostic tools, and did just about everything except take new files from downloaded Win 7 sp 1 64 bit ISO . Besides F Parameter, i have no cross reparse point from tweaking program,also ive tried everything even shut Avast off in services but somehow it blocks your program. Missing Microsoft xml parser ,tweaking program saying modify access controls lists on object %WINDIR%\assembly see if applicable file folder c:\Windows\assembly has an explicit ACE set and needs to be fixed.Also Windows\assembly temp has explicit ACE .Windows\assembly GAC_MSIL\IEEXEC Remote has explicit ACE set. Two more things and i think thats it Shane. ICS not started call to get named security failed,set ACL reading for SD failed cannot find file specified and Windows\system32\WOW 6432 node contains wild card. Last but not least,just past 2 days this has come up on monitor right after windows opens, [Shell class info] localized\resource name z @%System Root% \system 32\shell32.dll,-21787.Thats it and enough problems for sure, but with all those problems my computer still running and i can do what i want on it still ? But i did have like 332 errors in one day on event viewer.I know thats alot and i probably should have just listed exact problems.But i always do this. So, if you think i should just do my re-install with three disks , maybe you can tell me the best way to do.Disks come with no info whatsoever from US.ESTORE.ASUS.Com . Thats the only place i was able to get in this country. I had to get disks because Microsofts remote help in past installed Win & over my ASUS section on partition. Thank you for any help and thanks for getting back to me so quick before. Thankfuluser.
