When I try to run defrag , which ran well until a few weeks ago, I get the following error message

MMC cannot open the file C:|WINDOWS\System32\dfrg.msc.

The file exists, What can I do to overcome this problem?

It may be corrupt...

Try a third party defrag tool

It may not work though.

if you type in
MMC cannot open the file C:|WINDOWS\System32\dfrg.msc
into google the first link will tell you how to remedy your problem,

might be best to wait to see if someone else recommends doing this, im not sure how much trouble you can get into if you do it wrong?
