Devices is not and I can't find anything that make the system. Now that I've lost the system restore 12/01/16. How to make its new?

    I've updated my PC HP spectrum Pro 13 laptop with Windows 10, after her international (idt high definition audio codec) Audio is not working properly.

    It works with some sound of PCs and with a highres movie played with VLC but my main application of the company "Skype for Business" claims that the speaker not working and when testing with Deezer there is a horrible squeeking sound instead of beautiful music.

  • Why Windows high contrast doesn't work anymore since Firefox 29 and the theme of the Australia?

    In firefox, 28 and all versions before that when I had Windows High Contrast active firefox would also be in high contrast. This would make black Web pages and all the text would become white. Because of my disability which makes it much easier for me to see and walk through it. Since firefox 29 and the introduction of the Australia theme but it seems like a high contrast in windows is no longer supported by firefox. That's why I went down to firefox 28 in order to be able to navigate as I used to.

    There is a hidden value that needs to be modified in two places:

    Go to Options > content > fonts look and colours, click on 'Advanced' > uncheck allow sites to choose the fonts and colors
    AND
    Click on ok and the color... on the content page > uncheck the allow pages choose own colors other than above. Make sure that the background is black and white choice policies.

    Under windows if you have high contrast mode, please also try "use system colors".

  • Why youtube doesn't work anymore without setting 'security.ssl3.rsa_rc4_128_sha' in real life?

    After that it turns rc4 is safer, I changed all the security.ssl3 - variable containing the substring from rc4 to false. Still, everything worked well, including youtube.
    But 2-3 weeks, youtube has begun to make problems: about 70% of the time, the first video is clicked on, gave an error. I had to delete the cookie (although I don't know if this was really necessary) and reload the page. After a few tries, it would eventually work and no so all video-subsequent requests, until I closed firefox (and therefore remove the cookie) or remove the youtube cookie. It was kind of annoying, but videos always occurred after a few tries.
    Since the middle of this week, the described method no longer works. I understand, now I have to allow rc4 again, by changing "security.ssl3.rsa_rc4_128_sha" to true. I don't know if the error is due to firefox or google/youtube. I meen why google would downgrade to only allow a non secure encryption method? On the other hand: there are updates in firefox affecting the rc4?

    So my questions are: which side is the bug? And is there no workaround safe solution to ban rc4 once again, while using youtube?

    It is a problem with the server that hosts the video files and Google has chosen to only support what a costume (speed issues?) figure even if the server supports TLS 1.2 according to the test report, but I don't know if that makes a difference instead of using SSL3.

    I guess MS has started the "Anti-XP" campaign at the beginning and a doing, now XP, a PITA!

    Hi James

    What is your level of service pack? If you don't know, click Start, run and type "Winver" in the Run dialog box.

    Windows Update no longer works if you do not have Windows XP SP3 installed. If the previous step, you have confirmed that you don't have XP SP3 installed, you must download and install XP SP3 from the link below.

    Note: You can safely ignore the warning text indicating that this package is not suitable for the it professional and network facilities.

    Important: to avoid a scenario where your system enters a 'loop', due to the installation of XP SP3, you need to check and make sure that your processor type is not an AMD (HP) or non-Intel Processor. You must install the package below the link if yours is a processor not intel before installing XP SP3

  • Why google doesn't work anymore when I go to firefox

    whenever I try to check my gmail, firefox continues to indicate there were and question and im not connected. Now it wont let connect me to youtube. What can I do to fix this problem without having to get rid of firefox for good

    This problem may be caused by corrupted cookies or cookies that are blocked.

    Clear the cache and delete cookies only from Web sites that cause problems.

    "Clear the Cache":

    • Firefox/tools > Options > advanced > network > content caching Web: 'clear now '.

    'Delete Cookies' sites causing problems:

    • Firefox/tools > Options > privacy > "Use the custom settings for history" > Cookies: "show the Cookies".

    If the deletion of cookies did not help, then it is possible that the cookies.sqlite file that stores the cookies has been corrupted.

    • Rename (or delete) cookies.sqlite (cookies.sqlite.old) and delete the other files of cookies as cookies.sqlite - journal in the profile folder of Firefox in the case where the cookies.sqlite file has been corrupted.

  • Why the rejection of multiple photos doesn't work anymore when you change pictures?

    Why the rejection of multiple photos doesn't work anymore when you change pictures? Does anyone else have this problem? It works on my other Mac but just stop working on my computer laptop pro, I have the latest OS and it worked until a few weeks ago. Thanks for any help!

    Selection of several photos at once enter "9" to reject all still works them for me in Aperture 3.6 on El Capitan.

    Have you tested, if the problem occurs only in an Aperture library or libraries opening?

    Create a new Aperture library to test and see rejection, so it works.

    If it does not work in a new library either, I got trash Aperture preferences.

    In preferences file is now in the container folder in the user's library.

    Try this:

    • Leave the opening runs.
    • Then open your user library and delete the folder complete ~/Library/Containers/com.apple.Aperture/
    • and the ~/Library/Preferences/com.apple.Aperture.plist file

    Your user library can still be hidden. To reveal the hidden user library:

    • Bring the Finder to the front by clicking on the desktop or the Finder icon in the Dock.
    • Select your folder user/home (with the House icon in the side bar of the Finder)
    • With this window in the Finder in the front window, press the ⌘J key combination to bring up the display options.
    • In the view options panel allow you to "show the library folder. That will make your visible user library folder in your folder.
    • Open your folder, then the library folder, then the containers.
    • Move the entire folder ~/Library/Containers/com.apple.Aperture on your desktop. Move the entire folder, not just the content.
    • Delete ~/Library/Preferences/com.apple.Aperture.plist as well.

    Now, restart the Mac, start Aperture and try see your book.  If all goes well, delete the folder on the desktop.
