Hello grasshopper.

This problem may be caused mainly by broken printer drivers, this could have been caused when you installed the updates. I suggest that you start with a restoration of the system on the computer by choosing a restore point when it was working fine.

a. Click Start, type system restore in the search box and then in the list click on the system restore program.

b. If you are prompted for an administrator password or a confirmation, type your password or click on continue.

(c) in the System Restore dialog box, click on choose a different restore point and then click Next.

d. in the list of restore points, click a restore point created before you started having the problem, and then click Next.

e. click Finish.

You can see the following article for reference:

http://Windows.Microsoft.com/en-us/Windows7/products/features/system-restore

You can also try driver restore on the computer and check if it helps.

To roll back a driver in Windows send the driver to the version that was finally installed for the device. Restoring a driver is an easy way to return a driver for a working version when a driver update fails to fix a problem or maybe even a new problem.

a. open the Device Manager. To do this, click Start, type device in the area Manager search and then click on Device Manager in the list programs.

b. right click on the device for which the previous version of the driver is desired and then click Properties.

c. click the tab drivers.

d. click on Roll Back Driver.

  • External hard drive is not recognized after Windows Update

    Original title: XP Pro wants to install driver for external hard drive that is Plug-and-Play

    I think that using Windows Update can cause problems (unintentinally or not) for users of Windows XP.

    In a series of accidents with an old computer and reinstall the XP Pro operating system, I discovered that MS Money installing only if it was made before the Windows updates.  (planned obsolescense?) The issue has to do with the removal of the registry AUTORUN file. INF for some new and improved files through Windows Update.  Before the updates, the file exists, and I could install MS money.  After updates, AUTORUN. Missing INF file of the registry.

    Now, I encountered a new problem, and I think that it is also a result of Windows Update.  My external hard drive to IDE, that worked perfectly before on this computer (newer), is no longer recognized and want to reinstall the driver.

    The problem is that it is a Plug-and-Play device, and no driver was needed before updates.  I read somewhere in my many attempts to find a solution that the MS Plug and Play system was replaced by a universal version of this feature (UPNP?)

    It's on a more recent, computer replacement, which came not with a copy of the Windows XP Pro operating system, and I can't just reformat the hard drive and start all over again.

    Someone else has encountered this, and if so, have you found a solution?

    Double Post suite-

    Where is my external hard drive?

    I'm under XP Pro on a Dell Optiplex PC with all the current Windows updates (SP3. Net4, etc..) and last month, I added a USB IDE hard drive. the hard disk enclosure is MASSCOOL, and I used a 250 GB Seagate Barracuda7800. The car worked perfectly until this week. I had the Windows Update critical update automaticlly value and security updates.

    The hard drive has disappeared from "my computer." I tried to plug and unplug in different USB ports, restarted the computer, but continues to receive the "new hardware detected by saying me that new hardware has been detected and that I need to install the necessary driver.

    The problem is that Seagate does not provide any driver for this drive, because it is supposed to be (and was so far) recognized by the Plug-and-Play of Windows XP software. The hard drive enclosure came with a mini CD, but this contains software to use the unit as a back-up, not for storage.

    I can't understand that this change suddenly to believe that something in the Windows updates that have been installed recently changed the command structure, registry files or the drivers themselves.

    I know this is possible, because I've seen what's happened to any program that relied on self. INF file that was originally part of XP. This resulted in programs like Microsoft Money and older versions of MS Office, not being able to be installed by those of us who are not 'technically lit.

    I'm here in left field, or other people have had similar problems? And is anyone know how to solve this dilemma?

  • USB port not working after Windows updates

    My laptop does not recognize a USB device I've used in the past.  If I restart the computer after trying to plug it, I get a system repair and it cannot solve the problem.  The only way I could fix is to do a system restore in Sfe Mode, to a point, 2 weeks ago.  The only changes since then have been Windows updates.  How can I fix it

  • Constant pop up of the notice that says "USB device not recognized" after the device has been disconnected

    Trying to connect a Sony W760 to PC Suite and receive the notification as the "peripheral USB is not recognized. Clicked on the indications of alert and monitoring. The device is not installed. Computer restarted, but the alert keeps popping up every 10 to 15 seconds. How to stop?

    Found the answer to the problems by accident. I had turned off my Avast, during the installation of the programs, but did not know that the computer came with Norton already active. Nothing on the screen noted that it is there. The Sony site, under the heading troubleshooting USB and I saw it mentioned to disable McAfee. Became curious and went to control panel > programs and features looking around and found the Norton. Uninstalled, downloaded programs from Sony, install and everything works fine. Just a reminder, check all your security system before installing programs.

    Hi Paul,.

    Thanks for the reply with the status of the issue.

    It seems to be a problem with iTunes not with Windows. I suggest you try reinstalling iTunes and check if it helps. If the problem still persists, then try to install iTunes in Windows 7 compatibility mode and check if it works for you.

    Refer to the procedure described in article Microsoft Help that I provided in my previous reply to install iTunes in compatibility mode.

    Just reply to the State of the question so that we can help solve you the problem.

  • Brother printer and the scanner does not work after Windows Update.

    Separated from this thread.

    I have the same problem with my Brother ADS2000 scanner and my multi MFCJ4710.  I can print with the MFC, but the Control Center detects or scanners.  They worked and suddenly stopped.  I wonder if Windows update changed something?  Scanners both work with Windows Fax and Scan, but not Brother Control Center 4.  I called support of brother and again, they have said something about TWAIN and I have to do some registry clean.  I tried their manual steps, they sent with the registry fixes and which totally screwed up on my computer.  I had to do a restore and now back to square one.

    Any solution out there?

    It was my dose,

    (1) start search box type menu "user accounts".

    (2) open and select "user account control settings."

    (3) to change the cursor to "never notify".

    (4) 'ok' to save

    (5) fact! You may need to restart you machine.

    PS: this was my fix, it was caused by software AVG anti-virus, AVG has replaced this setting and would fail to wireless for my scanner. It will be useful.

  • Driver for my printer not recognized by windows 8. Device

    I tried to install an old printer in windows8. The pilot was not available and none was available at HP. I get the message not recognized usb device and I can't get rid of the message. Chat help or tech support Microsoft have not been able to help. all of the suggestions.

  • NB550D - does not start after Windows Update

    NetBook may have turned off during the update of Windows like now it will not go beyond the Green loading bar with 'Microsoft Corporation' below. It gives an option to start windows normally or to load files to repair, but the two find themselves stuck on the Green loading bar. SafeMode (all options) earn as much as classpnp.sys and then freezes.

    Using a different laptop I did a windows repair disc and then copied the files on the USB key (netbook has no CD drive) according to the guides online. When the USB key is loading files of repair, there is a flashing cursor, and then he's new to the Green loading bar. SafeMode (all options) gets stuck on disk.sys with inserted USB.

    Found a few threads with similar symptoms with most being caused by a questionable HD (verified, nothing obviously disconnected) connection or the SATA mode in the BIOS the wrong (seems to make no difference between ACHI or Compatible). Next plan is to start a live version of linux and try to replace the classpnp.sys file with on another copy of Windows 7.

    If anyone has experienced this before or can give indications that they would be much appreciated,
    Thank you.

    Hello

    To be honest, never had any problems after a windows update.
    But it looks like an anomaly in the system.
    My first idea was the use of the repair option and you try to start the operating system using the option: use the last known good configuration.

    But if it would not help, then you can try to replace the files to aid and booting from the Live CD. Not sure if this would solve the problem, but I think that it of certainly worth trying otherwise you will have to reinstall the OS using the HARD drive recovery (if still available)

  • Help, INternet explorer does not work after windows update

    One day, the computer automatically downloads and installs the programs that are recommended by microsoft windows.
     
    After installation, my INternet explorer does not work.

    Windows received an HTTP error message: 403 (refused).

  • Lightning will not rise after Windows update 10

    My computer came installed with Windows 7 Professional 64 bit. The computer has a Thunderbolt 2 interface. I loaded the software and the drivers were mounted and worked a lot their use in Garland.

    External drives are USB 3.0 and LaCie thunderbolt. The computer was shipped with the HP security software. I did the upgrade to Windows 10; in the Windows dialog box update, said could not be updated without removing the HP security. I said yes, and since that time, readers not only mount.  After the update, and readers would not mount. I then used system restored and returned the computer to Windows 7.

    When I tried to reload the drivers for LaCie drivers, I get cannot lack of file sysInfo.dll. I download this file, place it in the system 32 folder. After a reboot, I tried and the pilot program installed. However, readers will not rise. I contacted HP and they remote connected to my computer, BIOS update installed, chip set drivers and still drives don't mount not via the port of Thuderbolt2.

    They run a lot when it is connected to the USB 3.0 port. My logic is readers are very much like the mount and run fine with USB 3.0, but is no longer the mount with the crush. I am a photographer and work with large files often 1 GB or more. Thus, the impact of lightning speed is desired.

    I have the drive Professional OEM Windows 7 SP1, however I have a large amount of the image installed and that you hope to find a way to solve this problem without the operating system reinstallation and all the photo editing programs. A pre thank you for everything that helps her.

  • Qosmio F750 - touch buttons does not work after Windows update 10

    I use a laptop Qosmio F750 (PQF75A-02Y00Q).

    Installed on the computer the previous operating system was Windows 7 Home Premium 64-bit. Then, I upgraded the operating system to Windows 64-bit edition 10.

    As expected, this change would cause problems to appear. The thing that is really bothers me right now is that the touch of the keys in the top right of the keyboard do not work as expected.

    The buttons respond always if you touch them, but they do nothing on the screen. for the most part. When I touch the Volume Up / Volume keys down, they work as expected. However, the key Mute, the button Play/Pause, the Wifi key on / off and Mode (as well as the key to toshiba bulletin board) eco button do nothing.

    Curiously, when I manually turn eco mode from the power settings mode eco button again turns the green.

    My last question is, how can I fix this so that ALL keys work as expected?

    -----------------------------------------------------------------------------------------------------------------

    I noticed that the recognition facial webcam was funny things as well, but everything what needed to be done was to recalibrate the installation for that to make it work again.
    Curiously, all the FN key functions work well.

    In addition to the question in bold, there are all the other drivers should I install to improve/restore functionality to my laptop? As the page of Windows 8?

    Hello

    I have the same problem since update 8.1 and now after 10 update, even more I lost the 3d display function since I updated to 8.1.

  • Laptop HP - 15-r213ns: hotkeys (keys of wifi sound, brightness), does not work after windows update

    Hello

    I have a HP laptop - 15-r213ns (ENERGY STAR) with windows 8.1

    Last night, after an update of windows, the shortcut of the brightness (F2 and F3) volume (F7 and F8), wifi (F12) and keys all others have stopped working.  I can always change the brightness and volume using windows, but I can't do more using the keys.

    The function keys are working, as refresh F5 or F3 Browse. I noticed that before I had to press the FN key for this and now she does without the FN + Fx, so I guess that the update of windows must have changed something here.

    They used to work fine before the update. I reinstalled the display drivers (NVIDIA G-FORCE 820 - M) and looked for new drivers or update drivers using HP Support Assistant, but everything is up-to-date.

    I was looking for hot key factors in the page of HP drivers for my product but could not find any keyboard, drivers or software related shortcut keys.

    any suggestions?

    Thanks in advance,
