Free Way to Use and Mount Images (ISO files) Without Burning Them

   Posted by David Kirk in Windows

Microsoft has an unsupported virtual CD-ROM program. Why buy alcohol or Daemon Tools when you can use this free replacement instead?

Alcohol and Daemon Tools are excellent software packages that allow users to mount ISO files as virtual CD-ROMs. Yes, there is a way to use that ISO without burning it to a disk.

Although I love these tools, Microsoft has a free, 60kb program that does the same thing! Of course, it is not supported, and it is not as friendly as the software listed above. However, it works and it is free.

Here’s the download link:

Here is the readme text. Please note that the readme file is incorrect and that this will work with XP, Vista, Windows 7 and Windows 2008 server. Windows 8 supports ISO files without additional software.

Readme for Virtual CD-ROM Control Panel v2.0.1.1


System Requirements
– Windows XP Home or Windows XP Professional

Installation instructions
1. Copy VCdRom.sys to your %systemroot%\system32\drivers folder.
2. Execute VCdControlTool.exe
3. Click “Driver control”
4. If the “Install Driver” button is available, click it. Navigate to the %systemroot%\system32\drivers folder, select VCdRom.sys, and click Open.
5. Click “Start”
6. Click OK
7. Click “Add Drive” to add a drive to the drive list. Ensure that the drive added is not a local drive. If it is, continue to click “Add Drive” until an unused drive letter is available.
8. Select an unused drive letter from the drive list and click “Mount”.
9. Navigate to the image file, select it, and click “OK”. UNC naming conventions should not be used, however mapped network drives should be OK.

You may now use the drive letter as if it were a local CD-ROM device. When you are finished you may unmount, stop, and remove the driver from memory using the driver control.

    Thanks for the help.
    This is good and it works on Windows 2003. However, only you remove the driver you cannot install it again and it would probably need a reboot to be able to install it again.

  • Mark

    i really want to git this to work but every time i try to open the .sys thing in install driver window it says acess is denied and it wont work im currently running on windows vista is that a possible reason why its not working

    • Me

      Wow. Why is everything a pain in the butt with PCs? Something so simple takes so much work. I’ll stick to my Mac, thank you. Expensive but definitely worth it.

      • joe

  • Jhun

    Thanks for the information. Great! so easy.

  • Manphish

    Okay so I followed through with the instructions, and I’m sure that I messed up somehow, but the virtual drive that I mounted the .iso to just says “Windows cannot read from this disk. The disk might be corrupted, or it could be using a format that is not compatible with Windows.”
    Is it something I did? Or is it the .iso file that has the problem?

    • I just installed the tool – no problem here. I suspect that the iso-image is corrupt.
      By the way: thanks for the tip!

  • Shibu Dev

    Does it work with Windows Vista. I tried but failed.

  • ronzo

    thanks works great so far

  • BadBear

    Superb thanks, saves me loads of disks and hassle

  • mv288

    GoI suspected something like this. Am sure Microsoft teams wouldn’t be using
    all kinds of crap out there for this functionality. Perhaps there aren’t releasing
    this utility to not run into anti-trust and ridiculous US patent issues…and waste their time.

    Good Stuff.

  • Angey

    Can this be used with VIsta? Am having troulble after step 3, it says the ‘handle’ is invalid.

    • I use it with Vista but it is not as stable. I believe you have to run it as admin and in xp compatibility mode.

      • Dom

        Thanks for that. I loved this app on xp and was getting frustated that vista wouldn’t seem to work.

    • Kathleen

      On my machine, I was getting that error because I did not have admin rights on my machine and therefore could not update drivers (.sys file). Once I was granted admin rights, I did not see the “invalid handle” error

  • Gloudas

    Hey, I followed all the steps, everything seems to have worked just fine, but… I can’t actually use the image file itself. I guess I’m a little unclear on what this does.

    I have an ISO file, and I did everything on it, but its still just sitting there as a file. Is there some way I’m able to run it now, or what? If anyone could enlighten me on what I’m supposed to be doing or producing through this that’d be great.

  • Gloudas

    Nevermind, I figured it out.

  • eternam

    Thanks, helped a lot!

  • Naren

    Thank you very much. The tool worked fine, but now im facing problem while unmounting the drive. The stop button is disabled in the driver control window. I ve tried to remove driver but it was giving the following message.
    “The service cannot accept control message at this time.”
    Kindly telly me how to unmount the drive.

    Love it. thanks MickeyMouse !

    You dont have to install the VCDRom.sys in the systems32 folder. The link above is a winzip distributable. You can unzip the file contents to any folder. When it asks for the driver file, simply navigate to the folder where you unzipped the files to, and choose the sys file.

    Windows 7:

    When I hit Start, it says, “This driver has been blocked from loading.”

    I am running as administrator and as XP SP2 compatability mode.

    Maybe I should try putting the file in the system32 folder, someone said I did not need to.

    • Anon

      No, putting the file in the system32 folder in Windows 7 means it basically becomes invisible because I can’t see anything in the folder when I browse to it.

      What is a good light program without ads, spyware, or viruses, no 30 day periods, that can mount ISOs in Windows 7?

      I used Alcohol 52% just fine in Vista previously but now I can’t find a version that isn’t a 30 day trial or spyware that requires you to install some stupid toolbar to use the program.

      Thanks in advance for any help.

        I’m on Windows 7 64bit by the way.

        I tried Alcohol 120% and it did not work.

        Anyone know any programs that work on Windows 7?

        • Anon


          I tried Alcohol 120%, DaemonLite Free, MagicISO Maker, Virtual CloneDrive, I think I even downloaded a 64 bit version of one of them.

          I am on Windows 7 64 bit. None of the above programs worked, WinXP VirtualCD says, “This driver has been blocked from loading,” when I hit Start.

          I am running as administrator and as XP SP2 compatability mode.

          Alcohol 120%, DaemonLite Free, MagicISO Maker, Virtual CloneDrive, WinXP VirtualCD do not work for me on Windows 7 64 bit. I will have to make some DVDs with the isos I have but what can I do with a 7 GB iso? My DVDs are only 4.7 GB DVD+Rs.

          • Aston

            This VCDTool control tool isn’t working

            I’m running the program as Administrator, I’ve got as far as:
            1. Copy VCdRom.sys to your %systemroot%system32drivers folder.
            2. Execute VCdControlTool.exe
            3. Click “Driver control”
            4. If the “Install Driver” button is available, click it. Navigate to the %systemroot%system32drivers folder, select VCdRom.sys, and click Open.
            5. Click “Start”

            I then get:
            ‘This Driver has been blocked from loading’

            I’ve tried it in different compatibility modes and moving the file vcdrom.sys to a different location

            I’m on a Windows Home 7 64 bit OS

          • Anonymous

            I think it has been repeatedly demonstrated that using this tool likely will not work in windows 7.

          • It’s not actually Windows 7 – it’s any 64-bit OS.

            You can’t use 32-bit drivers (which is what vcdcontrol is) on a 64-bit platform.

  • jonny

    Uh… Daemon Tools works and it’s also free.

  • Worshak

    Okay, for anyone interested in this, listen up, it’s fairly straight forward.
    1) Not all ISOs, when put into file format, will work with this tool. Just happens sometimes.
    2) The install instructions are posted above, please follow those exactly.
    3) I did not create the .exe file, but I have used it before, and it is safe (as far as i can tell).
    4) The real goal is to prevent CD damage, and still have the functionality for your pograms.

    Works great!

  • thanks a lot! it works with my xp =D

    Tried it in Windows7. Running as Admin got me past the driver load error, but it blue-screened and my install divided by zero. Reboot, nothing. Win7 repair, nothing. So I safe-moded the sucker out of drivers and logged back in okay. Maybe try it on a 32bit system?

    It seems these awesome little virtual programs are being flushed by Microsoft. I see they’re possible thanks to the obvious Virtual XP deal Microsoft just released, but none of my old utilities have a chance. 🙁

      The image file is the file you’re trying to mount. They are sometimes called image files, iso files, etc.

  • Name

    I installed the driver per the instructions. My %systemroot% = C:WIN2K
    in the Driver control window appears the following:
    Virtual CD-ROM Device Driver : (??C:WIN2Ksystem32driversVCdRom.sys)
    then I close out of Driver control. and click “AddDrive”. This automatically populates Z: into the drive list. then as a test I open Z: from Explorer. I get a dialog requesting to isnert a disk. This appears normal and an approriate response given that I have not yet mounted an image file. next I go back and mount an image file.
    I do so by clicking mount then browse to an iso file. I double click the iso file which brings be back to the mount window. then I click ok. I get a message,” Mount Failed”, however in the drive list it shows Z: in the maped image field it shows ??F:Dirmyiso.iso
    I go back to explorer and try to open z: again. now I get and error stating Z: is not accessable. incorrect function.

    what’s the problem how can I fix this?

  • Why does windows need a separate download just to mount ISO images anyway? How very primative! In linux we can mount just be right clicking or using ‘mount -o loop ‘. SO much easier.

  • While I expect this information comes about 5 years too late…
    The ‘image file’ is the file that you want to mount. It usually have a .iso file extension.

    6 years later and this worked for me! I run WinXP using VirtualBox on a Fedora Host system. The pass-thru for the physical cdrom works but Windows XP was reporting the Office XP disc as unreadable. I created an iso of the disc on another machine but was then unable to install Daemon Tools Lite in the virtual machine! Anyway, I tried this method and it worked perfectly.

    OK, like many of you I had problems getting Virtual CD-ROM Control Panel v2.0.1.1 to work. I kept getting “the handle invalid” message. So after trial and error I finally got it to work on Vista 32bit and Win 7 32bit. Download the file and extract. Open the folder you extracted to, right click on VCdRom.sys and select copy. Go to C DriveWindowsSystem32Drivers, right click and select paste. Close window and go back to folder where Virtual CD-Rom is located. Right click on VCdControlTool.exe and select (Run as administrator). You should then be able to select Driver Control and Install Driver. Hope this clears up some of the confusion. Enjoy

    • wow i was just having problem and this solves it. Thanks you very much for the solution.

    My problem comes after copying VCdRom.sys into the the drivers file. I opened up the program and clicked Driver Control to get to Install Drive. The problem is is that I can’t install it. I see VCdRom.sys right there but it says that the handle is invalid. If you could help with this soon it would be greatly appreciated.

    Forget my previous post. A new problem has risen. I did all that Hang N Around had suggested which worked beautifully, but now my problem is that I can’t mount my iso on it. Strange enough I did it the first time in Admin but I couldn’t do it as just a regular user. Then when I tried to go back and try to mount it again it FAILS! Its bugging me but I will be looking more into it.Will keep posted if anyone wants to know if I ever fix my little problem.

    Well… After reading some of the comments… I just can’t understand them.
    If you calmmly read the instructions, it’s all there.
    I keep using it for some time (years) and I’ve never had any problems.

    Amazing, Thanx a lot

  • Mahenxx

    I NEed HELPP…
    When i now click on my computer there are lots of CD drives …..can somebody help me remove these..

    If it says “Mount Failed” that might be because the file name is too long. This programm can only read a certain number of characters in the path to the ISO file. Please add this to the guide.

    Or you can try stopping the driver and then start it again.  Worked for me. try stopping the driver and then start it again.  Worked for me.

    thank you, great tip

  • i  have used daemon tools all the time in the past but somehow it was crashing a server with RAID and not allowing the computer to boot up.. also it is adware now and a little annoying – so I am glad to find out about this MS tool.

    Cool/Hott recipe!!

  • The first priority of the site administrator for your comments right know, thank you. Really very good information-sharing gives you.

  • danny walker

    does this work on windows 7?

  • chariff

    Can I use the driver with *.bin file?
    I followed all your steps carefully, but I couldn’t mount the “bin” file?

  • AnnoyedGuy

    I have followed the instructions as given and reached the end. It states:

    “You may now use the drive letter as if it were a local CD-ROM device.”

    However, I cannot find the drive letter (I’m using Z:) under ‘Computer’ (I’m using Windows Vista).

    Am I missing something? Where is the problem?

    I have definitely done everything in the instructions, so how do I use the drive letter?

  • zippy

    Thanks for this, works a treat.
    Tried a second time though and Add Drive returns Add Failed.
    Any thoughts would be appreciated.

    Using dirty Vista (boo) but XP compatibility mode worked fine.


  • supyoyoyo

    Yeah i downloaded prototype the game, and it has this prototype.mdf file, and i try to mount it with this, BUT IT WONT SHOW UP!

    Tried with alchohol, deamon tools, this thing, AND NOTHING WORKS!!!


  • hussain

    thanks to how know the humanities for all.

  • Saeed Iranzad

    It doesn’t work for me. The main problem is that it doesn’t show the VCdRom.sys in the system32\dirvers folder.
    I have a Win7 64 bit version. Is the software working on 64bit Win7?

  • Saeed Iranzad

    It doesn’t work for me. It can’t find the VCdRom.sys file in the system32\drivers folder.
    Is this because of 64bit Win7 I have?

  • holly

    where does one find this %systemroot%\system32\drivers file? i am severely confused…

  • Thanks man it really useful tool for all.

  • Marc

    Microsoft Virtual CD-ROM is not stable on MS Mindows 7 (32-Bit) and does not work either for me on MS Windows 7 (64-Bit).

    Rather use Virtual CloneDrive ( or MagicDisc ( or ImDisk Virtual Disk Driver ( or WinCDEmu ( – All are freeware and support just about from MS Windows XP to 7 and 2008.

    Used to like Deamon-Tools ( the best, but they started to bundle too much spyware, addware and crapware into their installer – up to about v4.10 was still OK without all the badware in the installer.

  • Del

    Agreed, use Virtual Clone Drive. You can mount an iso or an img, you can allocate a drive letter of choice, tou can define the number of drives (or reduce it to zero to temporarily zap the program).

    I use Imgburn to write images to real disks.

    I’ve used the MS tools before but prefer the above as being a lot more controllable.

  • Walta

    in case the original MS download link does not work anymore, you can download it on CNet too
    I do agree with Marc and Del, it works with /up to Windows XP best.

    • david

      > thank you.

  • David Kirk

    Microsoft just released a new version, and I have updated the link above. This version works with XP through Windows 7. Windows 8 reads images files without additional software.

  • Vlad

    Spent 30min trying to get this working with Win7 before choosing Fail. Using the misleading readme was almost less helpful than going in blind.
