        The messy solution is to simply find the folder of the program you want to delete and then delete it manually. This doesn't clean up any registry entries the program might have on your PC, however, and won't remove any files the program has installed in common folders. A better alternative is to use a third-party uninstaller like Revo Uninstaller or AbsoluteUninstaller. This may take a little more time, but it will result in a more complete cleansing of the uninstalled program's files.

        Windows XP users should run cleanmgr from the Run menu while Vista and Windows7 users should do a Windows Search for Disk Cleanup. This will pull up a utility that can purge a hard drive of unneeded files like temporary files and files stuck in the recycle bin. If Disk Cleanup can't free up enough room to rid you of the error, you'll need to delete some programs that you no longer use or move files onto a secondary or external hard drive. Videofiles, image files, and music files often consume the most space on the average user's hard drive, so consider cleaning out and/or moving those first. A good program which can automate this cleanup process is CCleaner. CCleaner will remove all temporary files from web browsers, cookies, clear the Windows Recycle Bin, temporary files,log files and remove unused or old registry entries.

        Go to Folder Options in the Windows Control Panel and then click on the View tab. About halfway down the list, you'll see a checkbox labeled "Hide extensions for known filetypes." Uncheck this box and all of your extensions will reappear.

        Open the Control Panel and then the Networking and Sharing Center. Click on Manage Wireless Networks. Find the wireless network you'd like to use in the list and right-click on it, and then select Properties. Select "Connect automatically when this network is in range" in the Connection tab and enter the network's password, if any, in the Security tab. Click OK to confirm your settings.

        This problem usually occurs because there is already a microphone input set up on the computer and Windows is using it by default instead of the microphone on your webcam. Go to Control Panel and open the Sound menu, then click on the Recording tab. A list of installed devices will appear. Find the one related to your webcam and select it, then select the Set Default option at the bottom of the menu. It is also wise to disable all other microphones entirely to prevent any potential conflict, which can be accomplished by right-clicking on a device and selecting Disable.
