34 instances of mshtml.dll - can i delete any?

34 and counting. 732MB in total.

All but two of them are in amd64_microsoft-windows-ie-htmlrendering_31bf3856ad364e35_11.2.9600.xxxxx_none_xxxxxxxxxxxxxxxx.

What are they doing and do i need them? Help please? Thanks.

Thanks for the reply, and sorry, my question was badly phrased and not 100% accurate. All the mshtml.dll files except two are in C:\Windows\winsxs.

16 of them appear in windows search folder column in the form:
amd64_microsoft-windows-ie-htmlrendering_31bf3856ad364e35_11.2.9600.xxxxx_none_xxxxxxxxxxxxxxxx (C:\Windows\winsxs)

16 of them appear in windows search folder column in the form:
wow64_microsoft-windows-ie-htmlrendering_31bf3856ad364e35_11.2.9600.xxxxx_none_xxxxxxxxxxxxxxxx (C:\Windows\winsxs)

The other two are in C:\Windows\System32 and C:\Windows\SysWOW64

Windows Disk Cleanup should remove some of those. However, the cleanup steps below can take more than an hour to complete (or just a few minutes)... during which time, the computer cannot be used.


Start > search for Disk Cleanup.

Right click on the shortcut that the search should locate.

Select run as admin from the context menu.

Pick a drive letter (if need be) and let it scan.

Check everything and click on OK.

Agree to delete the files.

After the cleanup progress bar window goes away, restart the computer to complete the cleanup.

Do not manually delete anything in the Windows folder or it's subfolders. Except for real experts who thoroughly understand the implications these folders should be considered read only. There are many ways to go wrong.

Usernameissues - i use windows cleanup regularly and unfortunately it doesn't help.
Lmiller7 - sure, that's why i haven't touched them. I just hoped one or two of the experts here might have encountered this issue and a solution had been found.

I'm no expert but in my systems I leave winsxs alone. One must know when one doesn't know.
On my system winsxs are protected except for TrustedInstaller use. I leave it that way.
All those winsxs is not a problem.

I have the same idea i had before.
On my computers I just leave them alone.
I got 70 of them and I have no problems on this computer.
