Pls help with CPU usage!!!

Heck, if we're talking about things to run to keep your PC running smoothly, I'd also suggest CHKDSK, SFC, and DISM be added to the list.  At least once a month, I'd suggest running those little utilities to check for system file corruption and such, which can cause all sorts of unwanted and glitchy behavior.

Yes, very good things to add to a monthly maintenance routine. I completely forgot about SFC, good call.

Well, I do not know . . .I haven't done a defrag in two or three years. I had a problem with an external hard drive and checked all the drives and everything that was there. As the screenshot shows, there is still no problem today: zero defragmentation(Today 1% D:\). There is nothing more than zero.

I also did the other things with SFC Scannow  and so on at the time and I haven't used them since. Would that really do anything? . . I guess I'll have to test it out.

I think, from experience, faith plays more of a role than actual benefit. But as one pleases.

A lot of fragmentation depends on drive use.  I've got some drives that never get fragmented-- all they do is hold data for archival purposes.  Write once, let the OS auto handle them, and they're golden.  

I've got another drive, however, that's used in a more vibrant manner.  I'll download a torrent of several hundred GB of books.  Those then get copied to the temp drive.  Renamed.  Merged with a temp copy of existing books.  Duplicates purged.  Renaming goes up.  Series get moved into subfolders.  Finished contents are then moved oct to an archival drive...

That's a ton of data being shuffled, renamed, deleted, copied, pasted, and worked on.  **THAT** drive needs defragging manually as the OS just can't keep up with it on its own.

The OS tries to run at a schedule that works *for the average user*.  If you're much more abusive of your system than that, then the manual maintenance might be of use to you.  Otherwise, it's probably just a redundancy check more for peace of mind, than anything else.

(Where you probably NEED to run manual checks, is with network drives connected directly via your router.  No PC "owns" those, so they usually won't get automatically checked and repaired.)
