Windows 7 : Managing a User Account - Limiting Computer Access

Many children have access to computers. Some of these computers, such as those located at a school or library, are regulated by network domain controls or by the oversight of a teacher, librarian, or other concerned adult.

Windows 7 : Managing a User Account

The first user account created on a computer is automatically an administrator account—every computer must have at least one—so if yours is the first or only user account on the computer, you are operating as an administrator. You can create additional accounts for yourself or for other people who will use your computer.

Windows 7 : Understanding User Accounts and Permissions

The Windows 7 system of user accounts and passwords allows more than one person to use the same computer while providing the following safeguards

Windows Azure : Diagnostics

Logging support in the cloud is one of the biggest concerns of the developer community. With highly interactive integrated design environment (IDE) tools like Visual Studio.NET and runtime environments like the .NET Framework, you can pinpoint problems in you code even in deployed environments when applications are running on-premise.

Windows Azure : Common Storage Tasks - Utilizing Concurrent Updates

For any nontrivial application, you will have multiple clients talking to the Azure Table service at the same time. Concurrency becomes critical, since multiple clients could easily wind up trampling all over each other’s changes

Windows Azure : Common Storage Tasks - Modeling Data

For folks used to modeling data in an RDBMS world, not having the same tools (foreign keys, joins) in the Azure table world can be a bit of a culture shock.

Windows Azure : Exploring Full-Text Search (part 3)

You are almost ready to start indexing your literary classics. But first, you must add some stemming code. As you learned earlier, any nontrivial amount of text contains several variants of the same words: plural forms, different tenses, and so on

Windows Azure : Exploring Full-Text Search (part 2) - Building an FTS Engine on Azure

That was quite a bit of theory to set up what you will do next: build your own FTS engine on Windows Azure storage.

Windows Azure : Exploring Full-Text Search (part 1) - Indexing

Imagine that you’re implementing a search engine for your website. You could write some simple database queries to search your content.

Windows Azure: Building a Secure Backup System (part 6) - Uploading Efficiently Using Blocks

azbackup isn’t only about cryptography and security—it is also about providing a good backup experience (after all, it has the word backup in its name). The straightforward way to back up encrypted data to the cloud is to initiate a “Create blob” operation and start uploading data.

Windows Azure: Building a Secure Backup System (part 5)

Decrypting is the exact inverse of the encryption process, and the code is very similar to that used for encryption. In short, the following are the two steps for decryption

Windows Azure: Building a Secure Backup System (part 4)

Now that the key generation part is out of the way, let’s write the tool that generates the backup itself. You’ll be writing the code for this in a file called azbackup.py.

Windows Azure: Building a Secure Backup System (part 3)

Now that the transfer of data over the wire is secure, the next step is to secure the data when it has reached Microsoft’s servers. A reasonable question is, why bother? SSL protects against anyone snooping or modifying traffic over the wire

Windows Azure: Building a Secure Backup System (part 2) - Protecting Data in Motion

Any sort of cloud backup solution obviously must transfer bits to the cloud and back. An attacker shouldn’t be able to peek at your data as it is flowing through the Internet.

Windows Azure: Building a Secure Backup System (part 1)

When using cloud services, you often have to worry about security, and resort to cryptographic techniques such as digital signatures and encryption.

Understanding Windows Azure Roles

Each of these “types” typically has the same kind of code/software/bits running on that machine. All your web frontends typically have the same web frontend code, all your database machines have the same database software installed (with different partitions of data), and all your backend mail servers probably run the same mail transfer agent.

The Windows Azure Tool Set

You can evaluate policies against registered servers or an entire server group using central management servers. The great thing about evaluating policies against multiple servers is that you can simply click a check box to apply the necessary changes to the noncompliant servers.

Windows Azure Table Overview (part 2) - Azure Tables Versus Traditional Databases

The Table service in Windows Azure provides highly reliable, structured storage at scale. You can use Azure’s Table service in place of a traditional database to store all your data.

Windows Azure Table Overview (part 1) - Core Concepts

The Table service in Windows Azure provides highly reliable, structured storage at scale. You can use Azure’s Table service in place of a traditional database to store all your data.

Exploring Group Policy in Windows 7

The Group Policy Client service is a standalone service that runs under the Svchost process and no longer uses the trace logging functionality in userenv.dll. As a result, Group Policy event messages are now written to the system log with the event source of Microsoft-Windows-GroupPolicy, and the Group Policy Operational log replaces previous Userenv logging.

Working with Multiple Local Group Policy Objects

Multiple LGPOs increase flexibility when applying policy settings and allow home and workgroup users to gain some of the benefits and controls previously available only in Windows domains. They do this by allowing a policy to be uniquely tailored to users based on the logon account and their membership in specific groups.

The Windows Azure Sandbox

You might be wondering why you have to do anything special to run native code at all. After all, .NET has good support for interoperating with native code—from P/Invoke to COM Interop.

Windows Azure : Peeking Under the Hood with a Command Shell (part 2) - Running the Command Proxy

Build the package and deploy it to the cloud just like with any normal cloud service.Hit the public HTTP endpoint. Your browser should load the minimal UI built in the previous section. But the difference here is that any command now runs inside the virtual machine.

Windows Azure : Peeking Under the Hood with a Command Shell (part 1) - Building the Command Shell Proxy

One of the current downsides with running in Windows Azure is that you don’t get the usual set of tools to peek inside a Windows machine. You currently can’t use remote desktop, nor can you log in to the box and run a command shell.

Windows 7 : Using Any Search Engine from the Address Bar

Searching via the Search box is often easier than visiting the search engine’s site directly, but you’re limited to using either the default search engine or some other search provider that you’ve added to Internet Explorer.

Windows 7 : Understanding Internet Explorer Advanced Options

Internet Explorer has a huge list of customization features found in the Advanced tab of the Internet Options dialog box (see Figure 1). Many of these settings are obscure, but many others are extremely useful for surfers of all stripes. This section runs through all of these settings.
