WordPress .htaccess file

The WordPress core uses .htaccess for two things: Permalinks and Multisite. This means that .htaccess is only required if you have enabled either of these features. Otherwise, .htaccess is entirely optional for default WordPress installations. Beyond the WP core, many plugins also use the .htaccess file for custom directives involving rewrites, redirects, custom headers, file compression, and much more. In many cases, such plugins add their .htaccess rules to your .htaccess file automatically, behind the scenes. 
So even if you haven’t enabled Permalinks or Multisite, your site may be using .htaccess rules added by WordPress plugins for various types of functionality. That’s one of the cool things about .htaccess: it can be configured and customized to improve your site’s performance, security, and usability. To help you get started, this tutorial provides a collection of .htaccess techniques that are useful for any WordPress-powered site. Combined into a blank .htaccess file, these techniques serve as a great starting point for creating your own custom .htaccess file for WordPress.

Quick Tip: Add Computer to Group – GPUpdate without Restart

Let’s say that you have a GPO that is scoped to a specific security group. If you add a computer to this security group, you would normally need to restart in order for the computer to see that it is now a member of this group. To bypass this, you can delete the system’s Kerberos ticket and run GPUpdate. The computer will magically see its new group membership without a restart.

Hello Everyone, my name is Moni and I am a Support Engineer in the Windows Devices and Deployment team here at Microsoft. In this post, I’ll be discussing an issue where the Server Cleanup Wizard for WSUS 3.0 Service Pack 2 times out when attempting to delete computers that have not contacted the server in 30 days or more.

Details of the error are as follows:

Recreating the SUSDB and WSUS Content folder for a Windows Server 2012 based WSUS computer | SUS Blog

Occasionally you may find that you want to start over in WSUS with a fresh database (SUSDB). There can be any number of reasons for this, but typically I see people doing this if their SUSDB is rather old, has a ton of unneeded updates in it, and maintenance has not been done on the SUSDB in years. In those cases you can find that a rebuild may be faster and easier than fixing the problematic SUSDB. Typically speaking, I see people wanting to recreate the just the content dir if they accidentally unchecked the “download update files to this server only when updates are approved” and ended up with a hard drive full of unneeded files. Whatever the reason, here are the steps for recreating the SUSDB and the WSUS Content folder for a Windows Server 2012 based WSUS computer
