I am unable to scan a document from my HP printer via my Sony desktop running Windows 7 Home Edition. The computer does not recognize the printer even though it does when sending a print job to the printer. It is not an issue with my HP printer, since I can scan from it via my laptop. With help from HP, I am told that I probably have a corrupted WPA file. I cannot figure out how to download a fix from Microsoft. Can you advise?
WPA is Windows Product Activation. I'm not sure why that would interfere with your HP printer not working correctly. A system file check (sfc /scannow done from an administrative command prompt) may correct a corrupt WPA file, but before doing that I would uninstall and then reinstall the latest version of the HP print drivers for your particular model from their support website. If that doesn't work, try the system file check: click Start, type "command" and then right-click the returned Command Prompt link and choose Run as Administrator. Type sfc /scannow at the prompt.
I have been running Internet Explorer product version. It worked fine, then suddenly when I ask to open a URL in a new tab it comes out as a blank screen. If I ask it to open in a new window nothing happens.
Try running Internet Explorer in No Add-on mode: hold the Windows key and press "R", type iexplore.exe -extoff and click OK. If that solves the issue then the problem is one of your add-ons. Go to Tools, Manage Add-ons and disable all add-ons, then enable one at a time until you find the culprit (stop and start Internet Explorer after each change). If that didn't solve the problem, you can try resetting Internet Explorer to factory settings in Tools, Internet Options, Advanced, Reset. This will remove add-ons or extra toolbars you may have installed.
Search tips: Getting useful search results from Google or Bing gets harder every day with all the ads pushed to the front and links that have nothing to do with your search input. One way to minimize this is to use search directives: Put a "+" (no quotes) in front of any word required to be in the results. Conversely, put a "–" in front of any word to exclude results containing that word. Enclosing a phrase in quotes like +"Bucs Win" will ensure only results that contain that phrase will be returned.
