1. DVD audio problem
Microsoft has improved the hardware compatibility of Windows 7, but some users of older machines have reported that the volume when playing DVDs is very low or even there is no sound at all.
Solution: Open the control panel, enter the "Hardware and Sound" option, right-click the default player, select Properties in the pop-up interface, enter the advanced options, and reset the audio options.
If the above does not work, it is recommended to install a new audio driver.
2. MovieMaker failure
Improper user operation may cause Windows MovieMaker to be unable to import default network files. The problem can be solved with a quick registry modification.
Run the Regedit command, find the HKEY_CURRENT_USERSoftwareMicrosoftWindows LiveMovie Maker information line, and change the value of the "Allow network files" item to the startup state.
3. XP mode fails
The XP virtual mode in Windows 7 is a major innovation that can provide users with two operating experiences of XP and Windows 7. It not only solves the compatibility problem of old software, but also can take advantage of the new features of Windows 7.
There are usually three reasons for failure:
(1) XP mode requires CPU support, and Microsoft’s hardware virtualization auxiliary tool can be used to detect whether it meets the virtualization requirements;
(2) In addition, the virtualization functions of AMD-V, Intel VT, and VIA VT must be activated in the motherboard settings;
(3) The last reason is that some OEM manufacturers have banned XP mode for security reasons. Users can check whether it is banned in the firewall records.
If the above solutions are ruled out, it is recommended to download VirtualBox professional virtualization software, which can realize your wish to run XP in Windows 7.
4. Windows Media Center starts automatically
The media center function of Windows 7 is one of its features, but it is very troublesome to not support self-starting. Similarly, users are managed in the registry:
Run the Regedit command, find the information with the following name, and set the key value to EHome.
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionExplorerAutoplayHandlers
5. Lost system fault files
As impressive as Windows 7 is, it inevitably crashes. Sometimes, you want to view crash records through Windows diagnostic software, but find that no relevant records are found in the Memory.dmp file.
Solution: Right-click My Computer, select Properties, enter the Advanced tab, and select "Write events to the system log" in the "System Failure" column under the Startup and Recovery item. In this way, every system failure that may occur in the future will be automatically recorded.
