    Disable support for the tablet in the system control panel. Indeed, this can still bring your puppet tool, because I'm reasonably sure that the position of the icons is simply calculated wrongly because of this setting.

    My sisters thinkpad XP pro is unstable and it has lost its drive.  I can reinstall using my xp pro disk and its product key?

    I fixed it!

    I couldn't work at all Internet Explore.  I finally installed Superantispyware from a USB pendrive and it ran in safe mode without network.  So I ran Malwarebytes and ccleaner.  After a reboot, everything works great again.  I could install Microsoft Security Essentials and get current updates.  After a smart defrag it turns really well now.

    I was able to make a recovery cd set too.  It will be just as good as if I he burned them on a new computer?  I mean can the data used to make these CDs get corrupted over time?  This laptop is 6 years old.
    Thank you for your willingness to help.

  • Where can I find my original premodifie file on camera raw/bridge. This is the raw image before treatment

    Where can I find my original premodifie file on camera raw/bridge. This is the raw image before treatment. THX

    You can select the setting expand to default or previous camera raw conversion.

    You can also clear the changes to your image in Camera raw, but this will erase your changes in ACR.

    In Bridge, right click on the thumbnail of the image and select develop settings >Cancel settings.

    Hope that helps.

  • Where can I use my Microsoft Account expiration balance?

    I see this was requested, but I don't see a response that helps me.  Only, I logged into my account after a LONG departure.  It seems that I have a balance of $39, but I don't see anywhere that I can use it.  I do not have a Windows phone, or an Xbox.  Where can I spend it then?  I really don't want to lose $39, but it almost looks like what will need to happen unless Microsoft comes in and allows me to use and drop it elsewhere (the Microsoft store so I could at least buy some hardware)...

    Thanks for the help.

    PS - there is no category / topic for that matter...  Thank you.

    You can buy apps for Windows 8/8.1/10 also.  But yes, those who are for purchases of digital memory, not physical store in box item.s

  • where can I get CPU temprature in windows 7 (I know it's possible in the bios), but I want to know if this is also possible in windows 7

    Hello

    where can I get the CPU temprature in windows 7, I mean in what section of the control panel? I know that you can search the temprature of processor in the bios, but I want to know if this is also possible in the windows auto.

    Thank you

    Johan

    Hi Johan,.

    A processor overheating may fail or cause damage to other components in your PC

    Unfortunately, there is no built-in in Windows 7 utility that allows to monitor the temperature of the processor.

    There are some third party software that you can install the same.

    Note: The use of third-party software, including hardware drivers can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from the use of third-party software can be solved. Software using third party is at your own risk.

    It will be useful.

    Thank you and best regards,
