Defrag will not work

[Haylesfrend]

I tried to defrag my PC after it had come back from repair shop and I got
this message:
MMC cannot open the file C:\WINDOWS\system32\dfrg.msc
This may be because the file does not exist, is not an MMC console, or
was created by a later version of MMC. and so on about access rights.

I have emailed the repair shop and am waiting for a reply but also wonder if
the combined knowledge here can suggest anything

Probably not in a .NET programming discussion group, but you can find an
appropriate Windows group this way.

As you appear to be using a web interface, start here:

http://www.microsoft.com/communities/newsgroups/en-us/default.aspx

In the tree on the left, first open the English category, then open Windows.
In Windows, find and open the category for your version of Windows.
There, you'll find a group to post your question.
