FOR YOUR INFO. I run the maintenance wizard in full running mode no problem. How. By regularly cleaning out the registry and junk files with a combination of RegCleaner 4.3 (not RegClean, System Mechanic, (from www.iolo.com , be VERY careful) AdAware 5.82 , Pest Patrol, SpyBot and SwatIt. You can also get, for US$15, PowerDefrag from www.e-technik.com which runs scandisk and defrag in the same mode as when scandisk starts after a bad shutdown, i.e. before loading any other program. Users of Win '9x systems should be using DEFRAG.exe from Me to replace the '9x defrag.exe (renaming this to defrag.old and keeping a copy of DEFRAG.exe from Me on a spare diskette). You can run ScanDisk from the DOS prompt (C:\>)(especially when doing a full disc surface scan to keep the disk active and more receptive to data and to prevent data loss) using the Windows Start-Up diskette (bootdisk) made in add-remove programs in the control panel, which, when made should be booted up on and from A:\> go to A:\>C: (enter) to C:\> and type: C:\>sys C: (enter)To run scandisk type: C:\>scandisk /all and to do a system restore from the DOS prompt type: C:\>scanreg /restore. To delete the _RESTORE file type: C:DEL C:\_RESTORE and to delete the DATACOLL files type: C:\> DEL C:\WINDOWS\PCHEALTH\HELPCTR\DATACOLL\*.* , and for swapfile info go to: http://itcp.net/~awsh/Speed_Demonz/Swapfile_Optimization/Swapfile_Optimization_01.htm at Adrian's Rojak Pot forum.
