I had read a few threads about ........
1. Error 87
2.That it is not applicable to Win 7.
Since I have 3 machines with different versions of OS, I decided to check it out.
On each machine, I ran sfc /scannow, then after that, dism.
I found a thing or 2 perplexing.....
On my Dell laptop running Win8.1.1 Pro, sfc found no intergrety violation, but dism said corruption was repaired successfully. ( see screenshot #1.)
On my Acer Iconia W3-810 tablet running Win 8.1, sfc found no integrity violation, but dism returned with error 87, restore health option is not recognized.( see screenshot #2).
Same result applies to my Acer Aspire Win 7 Home Premium SP1.(see screenshot #3).
Can someone clearify for me ?
I might be able to explain screenshot #1. A few days ago, sfc was unable to repair corrupt files. Dism did the repair job for me.
But, most importantly why the error code 87 ?

Thank you for pointing it out. But, without the hyphen, the result is still error code 87.
This screenshot is from my Win 7 computer.

ScanHealth is running in both my Acer Iconia windows 8.1 tablet and Acer Aspire laptop Win 7 Home Premium.
Will take a while to finish.
I'll assume that CheackHealth will work too.
So, what gives on RestoreHealth ?
Don't tell me it returns error 87 because there is nothing to repair....... ha ha ha.

The plot thicken...............
On my Win 7 laptop :
ScanHealth ran successfully.
CheckHealth returned error 87.
On my Windows tablet, both ScanHealth and CheckHealth ran through successfully.

Most of the references that I can find regarding that particular error suggest a syntax error with spacing, spelling or missing or incorrect slashes before the various switches..... which doesn't appear to be the case at all.
So maybe the /ScanHealth or /CheckHealth may provide some insight. If not maybe consider perusing the log file.

Well on the Windows 7 machine I believe that some of the DISM command line switches are unavailable.
Have you performed a /? switch after the Dism /Online /Cleanup-Image to see if the /RestoreHealth switch is available for Windows 7?

In case you have overlooked......
My Win 8.1 tablet also returns error 87 on RestoreHealth option.
OK result of /? switch......
Apparently my Win 7 is missing RestoreHealth and CheckHealth options.
That explains why both commands failed.
SO...... how do I have the missing switches restored to my Win 7?

Wait. My Win 7 is a pre-installed OS.
It has never been upgraded.

Haven't forgotten or overlooked.... just thought we would deal with one device at a time.
As best I can tell.... It ain't gonna happen. The DISM utility in Windows 7 was still barely emerging from its' infancy. It has become more robust with Windows 8 and going forward but as of this point it doesn't seem to be retro'd back to Win7.
Now regarding your tablet.....
I was hoping that the two other switches after having completed would provide some insight but..... that doesn't seem to be the case.
So, can I suggest a "Clean Boot"
http://support.microsoft.com/kb/929135
And attempting the /RestoreHealth under those conditions.

OK. If I gather up enough courage, I may do a Recover.
The tablet comes with 2 Recovery Disks
Being a tablet which does not have a dvd/dw drive, I bought an ext. dvd/dw drive.
I am still waiting ( from eBay) for my Micro USB Dual OTG Hub Cable in order to connect my ext. drive to my tablet.
I won't dwell into this subject anymore.
Thank you.

Help requested.
I have been trying to repair my laptop filesystem using DISM. Previous attempts have failed (source not found). Today I try with a slightly different command line and get Access Denied.
I reduced the command line to
dism /Online
and still get Access Denied.
This is being run under Win 10 Administrator Command Prompt, as before.
Can anyone advise me what I have done wrong, and how to continue.

You need to specify your source
Dism /Online /Cleanup-Image /RestoreHealth /source:wim:X:\sources\install.wim:1 /limitaccess
Where "X" is the location of your installation files (DVD or mounted Windows 10 ISO)
