• Laptop HP 15-R204NE: cannot open Device Manager?

  Hello

  I'm having the following problem when I try to open the Device Manager:

  

  He asked the permission of the Microsoft Management Console before giving me this message.

  This started happening after I installed and uninstalled multiple copies of Visual Studio and MS Office, because I had problems. My laptop is passed to control drive C before starting to check for errors and repair them.

  Can someone provide a fix for the problem please?

  I highly appreciate the help.

  Kind regards.

  The extent of the corruption of files on your system may be beyond any simple diagnosis and repair.

  I think your only option now is the restoration of the system, a repair or re - install. Restoration of the system from an earlier date is easier, even if you indicated that you do not want to. If you do not have the support of HP Recovery then your Windows recovery options are explained here:

• Error when you try to open Device Manager in Windows 7 Professional.

  When I try to open Device Manager or the computer management window, I get an error message similar to the following:

  MMC cannot open the file C:\WINDOWS\system32\devmgmt.msc.

  It is perhaps because the file does not exist, is not the MMC, or was created by a later version of MMC. Perhaps it is also because you don't have sufficient access to the file.

  File c:/windows/system32/devmgmt.msc has the tool box is red (which I think its usually grey (normal))

  Hi GodzillaSurfer,

  Try these steps and check if it solves the problem:

  1. Click Start , type cmd, right click and select run as administrator.

  2. at the command prompt, type regsvr32 msxml3.dll , and then press ENTER.

  In addition, if the step above does not resolve the problem, you can run a scan of auditor of file system (CFS) on your computer. SFC tool scans system files and replaces incorrect versions of system files by using the correct versions.

• I can see is more devices in Windows 7 64 bit device manager

  I just got a laptop (2.67 GHz quad core i7).  It had Windows 7 Pro 64 bit responsible.  I tried to clean up some unwanted 'free' software.  When I went to the Device Manager to check on a device, nothing was in the window.  There are no hidden devices.   Everything seems to work, but I don't see all the devices in the window.

  Hello

  What is the brand and model of the computer?

  When you open Device Manager, no devices appear in the list. Instead, a blank window appears.

  This problem occurs if the Plug-and-Play service has been disabled (disabled).

  Method 1:

  To resolve this problem, set the startup type for Plug-and-Play on automatic. To do this, follow these steps:

  a. Click Start and run, type services.msc, and then click OK.

  b. double-click Plug-and-Play. If you receive a Configuration Manager message, click OK.

  c. in the Startup Type list, click Automatic, and thenOK.

  d. close Services.

  e. restart the computer.

  Method 2:

  The other reason, Device Manager may be empty is because there are some security issues with the registry key.

  Note: serious problems can occur if you modify the registry incorrectly. Therefore, make sure that you proceed with caution. For added protection, back up the registry before you edit it. Then you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article:http://windows.microsoft.com/en-US/windows7/Back-up-the-registry

  a. click on start-> Run-> type regedit.exe.

  b. search for the following: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum

  c. now right-click on Enum and click Permissions.

  d. click on the Add button and type everyone, and then click OK. Check the box allow next to the reading for everyone. Now click on add and enter the system. Check the box allow next to the read and full control to the system.

  e. the two check boxes under allow must be selected when you highlight the system. Also be sure to click on the Advanced button after adding the two users and select Reset entry permission on all child objects with the entries displayed here and that apply to child objects. Click OK.

  f. restart your computer now and check if the problem persists.

  Method 3:

  Perform a SFC scan on your computer. Consult the following link:

• Combo DVD/CD drive does not appear in Windows Explorer or the Device Manager

  The combo DVD/CD on my laptop drive isn't in Device Manager or Windows Explorer.  The door is not ejected.  You must use a paperclip, poking into the hole to open it.  I also re - it sitting, but it changed nothing.  We had this laptop for 1.5 years and the disk worked great until yesterday when trying to install Starcraft II.  Installation failed and it has messed up also the DVD/CD drive.

  We read some other difficulty advice and tried the upper and lower filters in the registry, but there was no entires of upper and lower filters in the key.

  The specifications of the laptop are:

  HP Pavilion dv7

  Processor Dual-Core Mobile RM-72 2.10 GHz AMD Turion X 2

  4 GB OF RAM

  a process that solves the problem.

  Try this - Panel - Device Manager - CD/DVD - double click on the device - driver tab.
  Click on update drivers (this will probably do nothing) - RIGHT click ON the drive - uninstall.
  RESTART this will refresh the default driver stack. Even if the reader does not appear to continue

  Another possibility is that the cables are loose. Remove ALL power, then make sure that the cables in both
  ends. Remove and replace, do not just tight. For laptops, you can often clean power and
  contacts data with a pencil eraser.

  Some DVD players do not use the Windows default drivers so check with the manufacturer of system and
  manufacturer of device to see if there is a firmware or drivers for your drive if necessary.

  ===============================

  Step 2: You have disc problems as the CD/DVD is actually 4 discs in 1 case (CD & DVD
  Burn and CD and DVD read). So it is not unusual for 1 or 2 operational so that other parts
  do it right.

  Did you follow the Troubleshooting Guide for the reader who still does not work? There are
  the entries in registry that the troubleshooter does not solve and those who "might" be the cause.

  Check with your Maker system and a device for the two possible firmware updates and
  the correct registry entries for your car.

  Here are the keys that I of course are those in question - for the subkeys of the CD/DVD drive
  as there will be other subkeys in these keys. Do not forget to ask specific keys involved as well as
  the parameters.

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\IDE

  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Hardware Profiles\0001\System\CurrentControlSet\Enum\IDE

  In respect of game controller does not appear even when you click advance to selected the device it does not always show upward.

  When I press the button the controller guide, it just keeps blinking as if it must be syc (but it connect through a wire that shouldn't happen)

  I tired using different drivers the same problems, I was installed the drivers off Windows 7 support site exactly the same problem...

  I also tried unplugging all the USB devices on my computer and plug the controller Xbox 360 on USB port which are directly mounted on the mother exactly the same problem.

  Up to now NO solution.

  Unfortunately, this won't work.  The Play and Charge kit connects only up to the actual battery.  Still, the controller connects more wireless.

• 10 Windows Update has failed, restored for Windows 7 - cannot open existing files

  Oh boy, am I ever stressed.

  My update of Windows 10 failed today (error: failure of page in nonpaged area).  I will have that later - my immediate problem is that when the update failed and stopped, it is automatically reduced to Windows 7 and all of a sudden I can't get all my Word or Excel files.

  More specifically: I can't open my files in Word or Excel, except those saved on the desktop.  Desktop files open fine, but whatever it is saved in a folder or other location does not open.   Other types of file open: photos, Photoshop, PDF, apparently everything opens without a problem.  For Microsoft Office files, I get the following messages:

  For Excel:

  Excel cannot access "File Name.xls". the document may be read-only or encrypted.

  and

  "File Name.xls" are not accessible. The file may be corrupted, located on a server that is not responding or read-only.

  For Word:

  Cannot open the document: user does not have access privileges

  Possible Note:

  1. I registered normally (as an administrator).

  2. when I right click on the file and look at the properties, everything seems normal (read-only is not checked, and the location of the file looks correct.

  3. I tried to pass a doc to a folder on my desktop.  It says that I have to give permission to the administrator.  I am able to click on the button 'continue' admin, the file is moved to the desktop, but still does not open.

  Any advice would be welcome!  I'm not a computer expert, and I desperately need to access my documents.

  So I clicked 'Add', typed the username- desktop\user name in the subject box, and then clicked on "Check names", then press the OK"" button.

  And now, the file opens.

  I'm sure there's a better difficulty out there, I don't know what it is.  Whatever it is, I can access my files now.

  You have made the right choice. It is essential that the specific user or group 'everyone' has full access to the file or folder. The alternative would be to use the console commands. They require a good knowledge of administrative tools.

  Be sure to mark my suggestion as "Response" to this topic.

• Windows 7 cannot open com1

  I have 6 computers Toshiba Tecra all bought to use the com port to communicate with data loggers. as provided by Toshiba, they work very well, as soon as they update of windows I get the message cannot open com 1, I have a scanner and nothing else is using the port. If I uninstall the driver of RTP com and reboot it all works, but it is temporary when you restart is not open, I guess it's a windows update issue 7 and follow the procedure to install updates one at a time, but still without success. Windows 7 pro 32 bit as computers alll provided behave the same way. any suggestions?
  I tried many programs of comms and the fertile, one for the data recorders that give the same result in train to test with hyper terminal.
  All updates of drivers and bios are up-to-date Toshiba cannot but feel it should be a problem to update.

  Thanks Dave K

  Hi and thanks for the suggestion, but it's a physical series RS232 port so not concerned by the firewall.
  I solved the problem which turns out be due to an update to Adobe acrobat reassign the PDF printer to com1. Microsoft to not update as I thought.

  Thanks again.
