Solutions: Putting an end to screen resolution changes

I have Windows 7 Home and Student Edition on a Dell Inspiron computer with 500GB hard drive and 3 gigabytes of RAM. When I use Windows Live Mail and Messenger the screen resolution changes to Windows Basic. It tells me that Windows Live and Windows 7 are incompatible. It involves Windows Aero. I used the Troubleshooter but it does not correct the problem. I can manually change the resolution back to the right configuration and proceed to use Windows Live, but it is aggravating to have to do that. Any suggestions?

I couldn't find any information on Windows Live disabling the Windows Aero feature. I know several Windows Live anomalies sometimes go away on a Windows Live uninstall/reinstall, but first I would check your video driver. Go to the Dell support website for your model PC and check to make sure you have the latest update version for your video. Windows will also turn the Aero feature off if it senses that the computer's resources are suffering. Go to Control Panel and make sure High Performance is selected under the power plan options.

I use Windows 7 Home Edition and Live Mail. When opening mail I sometimes get the following message, "A problem occurred while trying to open this message. A problem has occurred. Please try again." Repeated tries result in the same message. Sometimes I can go to an earlier received email and read the message, open it and work back up to this new message, and it will open, but not always.

Try this: Close out of Windows Live Mail. Go to Control Panel, Programs and Features, and right-click Windows Live Essentials 2011 and click Uninstall/Change.

Select "Repair all Windows Live programs" in the dialog box. After the repair is done, reboot when asked.

I have Windows XP, SP3. I have acquired PureHD somehow. It is interfering with and sometimes preventing me from playing DVDs, and it appears in other applications. It seems to have been part of another program and it has corrupted these files. I am unable to delete suspect programs from the control panel. The delete command freezes up the computer, and I have to pull the plug to exit.

PureHD is part of the Corel PaintShop programs and your problem is a known issue. You may want to go to their support website ( and click the Patches & Support link on the left to see if they have program updates that address your issue. There is also a registry fix that has been known to work. Only do this if you're comfortable editing the registry and understand how to back it up and restore if needed. Click Start, Run and type Regedit and click OK.

Move down to HKEY_CLASSES_ROOT\CLSID\{DBD8E168-244D-448C-9922-25508950D1DC} and delete the USIShellExt key.
