Let me elaborate a little more on the three main reasons why you should install the latest Windows security patches and updates.

1. Protect Your System From Malicious Software
Hardly any code is perfect and sooner or later weaknesses will be identified. Security issues are the worst possible errors, as they may be exploited by malware to access and potentially damage your system.
Security issues are regularly identified in various parts of the Windows operating system, including ActiveX, Internet Explorer, .NET Framework, or the main platform. Even if you do not run the respective software, it is a risk not to patch it, simply because it is installed on your system.

2. Resolve General Windows Issues and Bugs
The second type of update addresses more general bugs and issues of the Windows operating system. These updates typically contain several fixes in one go.

3. Access New Windows & Software Features
Finally, Windows updates often introduce new features, while also fixing some known issues. A good example is Internet Explorer. Even if you don’t plan on using the respective software, you should still run these updates, considering they often come with significant improvements and you may end up being forced to use the software after all. Moreover, Microsoft will eventually cease support for outdated software, e.g. old versions of Internet Explorer. This means that if new vulnerabilities are discovered, they will not be patched, as users are expected to run the latest version of the program.

As Windows 8 is coming to release, thus we need to prepare for updating to Windows 8 which may make our laptop more secure. Still, there are so many Windows 7 users who need to create a login password for preventing from prying eyes. Of course, at the same time we will encounter the trouble of lost Windows 7 password. Therefore, Creating a Windows 7 password reset disk is in necessity.

Answer: You can recover deleted files by restoring the deleted files from the Recycle Bin (Depending upon your operating system, your deleted files are temporarily sent to the Recycle Bin or the Trash Bin.) or you may be able to recover deleted files using a file recovery program.

Here’s the method you should use to recover deleted files:
1. How to recover the deleted files from the Recycle Bin?
The Recycle Bin should be the first place you look to recover deleted files. If you haven’t yet emptied the Recycle Bin, your deleted files will still be located here. You can recover deleted files from the Recycle Bin by simply restoring the files to their original locations.

2. How to recover the deleted files with a Free File Recovery Program?
If the files you’re looking for have already been emptied from the Recycle Bin, you can attempt to recover them using a file recovery program. You can improve the ability of a file recovery program to recover deleted files by installing and running the program as soon as possible after deleting a file.

Unlike file recovery, Windows password recovery can be worse annoying if you can not login your computer. I am a Windows 7 user and i have set password protection. However, it bothered  me much before that someday i forgot Windows 7 password and could not gain access into my pc, which made me crazy that my thesis has been locked. Finally, i was told to download an efficient tool – Windows Password Breaker for my Windows 7 password recovery.
