When you don’t need certain a program and try to uninstall it, sometimes a problem may occur preventing it from cleanly installed. In other cases, some programs may even refuse to be uninstalled perhaps because of compatibility when Windows had been upgraded. The following free program may do the trick in a very respectable way. Give this a try.

You probably have heard of Windows 8 to Go, which allows you install a portable version of Windows 8 on a Microsoft certified USB flash drive. If you are addicted to the old operating system (OS) Windows 7, you may wonder is there a way to install Windows 7 on USB removable storage device?

With Windows 7 on a USB flash drive or external hard drive, you can take it with you wherever you go and run Windows7 on any PC.

Windows Setup can detect USB hard drive, but when you select the external drive as the target location to install Windows 10/8/7, you will get the error “Windows cannot be installed to this disk”. Luckily, there is a workaround for this, and it is quite simple. Even those who does not know how to install Windows from a USB drive can follow this guide to get it done. (read the whole story)

The two commands that users require are Del, for deleting files, and Rmdir, for removing directories.

• Tap on the Windows-key, type cmd.exe and select the result to load the command prompt.
• Navigate to the folder that you want to delete (with all its files and subfolders). Use cd path, e.g. cd o:\backups\test\ to do so.
• The command DEL /F/Q/S *.* > NUL deletes all files in that folder structure, and omits the output which improves the process further.
• Use cd.. to navigate to the parent folder afterwards.
• Run the command RMDIR /Q/S foldername to delete the folder and all of its subfolders.

The commands may require some explanation.

DEL /F/Q/S *.* > NUL

• /F — forces the deletion of read-only files.
• /Q — enables quiet mode. You are not ask if it is ok to delete files (if you don’t use this, you are asked for any file in the folder).
• /S — runs the command on all files in any folder under the selected structure.
• *.* — delete all files.
• > NUL — disables console output. This improves the process further, shaving off about one quarter of the processing time off of the console command.

RMDIR /Q/S foldername

• /Q — Quiet mode, won’t prompt for confirmation to delete folders.
• /S — Run the operation on all folders of the selected path.
• foldername — The absolute path or relative folder name, e.g. o:/backup/test1 or test1

If you would like to rip a DVD with multiple audio tracks (e.g. karaoke discs) into individual files for each chapter, you can consider using an old and primitive program called SmartRipper (but it works, even in Windows 10). Change the settings to split files by chapter and you will get a VOB file for each chapter in the DVD title. Rename file extension from VOB to MPG. All audio tracks will be preserved. Download the program from this link. There is no installation; just run the application after unzipping the downloaded file.

If the router runs into a problem of 100% CPU affecting the internet connection, normal courses of actions include re-booting the router, power recycle the router and applying the latest firmware.

If none of the above works, check the computers that have a wired connection to the router. The problem may be caused by one of those computers that require a restart after Windows update. If that is the case, simply restart the computer to finish the update process and the router problem should go away.
