  • My computer has lost the password

    Hello Microsoft,

    MU is called dogman_1234. Look, the administrator of my computer lost the password, not me. There is nothing that I modified the software on Vista. I've tried Safe Mode, I tried Password Recovery "Ophcrach" and the computer has no other user with administration rights. Please, tell me how can I recover the administrative privileges or even create new password for the administrator?

  • My computer has lost the ability to go in mode "Eve".

    From a windows update last Saturday, my computer has no opportunity to use mode 'sleep'.  It's just one of the many changes that have occurred since the update: display is distorted, screen saver does not work as it did previously, sleeping capacity mode disappeared, etc..  I am very frustrated.  I have nothing but turn off my computer to allow updates to day, then when I turned it back on, everything was different.  I tried to set each of these things, but have had no luck.  Any suggestions?

  • CC for desktop computer has lost the applications Panel. How to fix this?

    I'm on a Mac (Yosemite) and a University wide subscription plan, and everything was fine until a couple of weeks a go. Problems began with a recent update to Dreamweaver which she returned to a status of the trial. Yesterday I updated to Lightroom 5.7, which returned Lightroom to the status of trial as well. No one here knows why and how to fix.

    But now I see that the Panel of apps in the application of CC desktop disappeared, all of the panel, not only the apps as others have described, which makes this application basically useless for me.

    It's a matter of preference, or anything more complicated? How can I remedy to get back on the Panel of apps?

    Thank you.

    Interesting. In a desperate attempt, I found and deleted several folders OOBE (Out of Box Experience) on my Mac and backup HD, has revived the CC desktop application and everything is back to normal again. Just lost nearly 4 hours trying to solve this nuisance. Some people here suggested to rename or delete the oobe.db file, but that alone did not do.

    Now, if someone could help me understand why the Dreamweaver update returns my application to the mode of trial and how to solve this problem, I would be grateful.

  • Time Capsule has lost the Internet connection and DNS servers

    I use a Time Capsule for Time Machine via Ethernet backups for a couple of years, use it in mode bridge taking its Internet connection directly from my router and connected in turn by Ethernet to my iMac. (Most of the time that I also had wifi off on my iMac and took my Internet directly via the TC Ethernet connection.) A few months ago I upgraded to El Capitan, and the TC has lost its connection Internet (flashing yellow). A few days later I drove back to the Yosemite (for other reasons - Mail had gone mad) to restore a backup of the TC and everything was fine again for a few months. It may or may not be meaningful I plugged TC yesterday to new laptop for my wife to support for the first time, and this laptop is running El Capitan. Since then, the TC has once more lost its Internet connection and DNS settings and is stuck on flashing orange. By clicking on the 'Internet connection' status alert, tells me that the TC is not a valid IP address.

    I have reset the TC, repeatedly and reconfigured but all without success. After consulting the other discussions, I also tried giving the unit an alphanumeric name with no spaces & special characters and change the IPv6 "Link-local" configuration only, but this did not affect the result. And I updated the firmware for good measure. Then I unplugged overnight and carried out a full power cycle the steps recommended here, restart the router, TC and the computer (and performed a factory reset on the TC, while the router & computer was turned off). After doing that, the TC has become undetectable by AirPort Utility, until I have reset reconfigured once again, he and ended up in the same place.

    It may or may not be important to mention the following:

    1 when you set the TC after a reset, I repeatedly selected the option of adding to an existing network instead of create a network, but the installation wizard who ignored each time.

    2. in the installation each time, this point, I shows me the following, which seems to suggest that there is a problem but don't say so explicitly:

    I would be grateful for any advice.

    Weird how everything's going well for a few years and then crazy when you have something will change.

    El Capo adds some network problems more... but something could be fundamentally wrong with the installer.

    Your current configuration, it is apparently bridged but cannot get an IP address. The address 169.254 is give it since it's self generated.

    You need to do a manual installation. It simply means the Assistant is unable for any reason to be your network so start over and do it manually of misfortune (wow, or also possible misery, woah being where you are now!) to go...!

    1. I need to know what modem you are connected. Make and model please?

    2. the most important. What is the main router on your network or a modem?

    I gave the edge to make manual settings a few times. Somehow my instructions for Yosemite/El Capo got lost... I'll try and hunt down them. In the meantime, the basic method remains the same.
