How to completely disable Cortana on Windows 10c

Cortana is very integrated with Windows Search and fully disabling it will break Search. However, if you would like to keep Search functional, you can just disable the “Cortana-y” parts of Cortana.

To disable Cortana in windows 10

  1. Press Win + R keyboard accelerator to open Run dialog box.
  2. Type GPedit.msc and hit Enter or OK to open Local Group Policy Editor. Navigate to Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Search.
  3. In the right pane, double click on policy named Allow Cortana.
  4. Select the Disabled radio button.
  5. Restart the PC and Cortana and Bing Search will be disabled. (May work after signing out and in again)

Policy Description

This policy setting specifies whether Cortana is allowed on the device.

If you enable or don’t configure this setting, Cortana will be allowed on the device. If you disable this setting, Cortana will be turned off.

With this set, users will still be able to use search to find things on the device and on the Internet.

Zimbra MTA

The Zimbra MTA (Mail Transfer Agent) receives mail via SMTP and routes each message, using Local Mail Transfer Protocol (LMTP), to the appropriate Zimbra mailbox server.

The Zimbra MTA server includes the following programs:

Postfix MTA, for mail routing, mail relay, and attachment blocking
Clam AntiVirus, an antivirus engine used for scanning email messages and attachments in email messages for viruses
SpamAssassin and DSPAM, mail filters that attempt to identify unsolicited commercial email (spam), using a variety of mechanisms
Amavisd-New, a Postfix content filter used as an interface between Postfix and ClamAV / SpamAssassin

In the Zimbra Collaboration Suite configuration, mail transfer and delivery are distinct functions. Postfix primarily acts as a Mail Transfer Agent (MTA) and the Zimbra mail server acts as a Mail Delivery agent (MDA).

MTA configuration is stored in LDAP and a configuration script automatically polls the LDAP directory every two minutes for modifications, and updates the Postfix configuration files with the changes.

Zimbra MTA Deployment

The Zimbra Collaboration Suite includes a precompiled version of Postfix. This version does not have any changes to the source code, but it does include configuration file modifications, additional scripts, and tools.

Postfix performs the Zimbra mail transfer and relay. It receives inbound messages via SMTP, and hands off the mail messages to the Zimbra server via LMTP, as shown in the following figure. The Zimbra MTA can also perform anti-virus and anti-spam filtering.

Postfix also plays a role in transfer of outbound messages. Messages composed from the Zimbra web client are sent by the Zimbra server through Postfix, including messages sent to other users on the same Zimbra server.

Figure 6: Postfix in a Zimbra Environment

6 MTA.5.1.1.jpg

*The term “edge MTA” is a generic term referring to any sort of edge security solution for mail. You may already deploy such solutions for functions such as filtering. The edge MTA is optional. Some filtering may be duplicated between an edge MTA and the Zimbra MTA.

Postfix Configuration Files

Zimbra modified the following Postfix files specifically to work with the Zimbra Collaboration Suite:

main.cf – Modified to include the LDAP tables. The configuration script in the Zimbra MTA pulls data from the Zimbra LDAP and modifies the Postfix configuration files.
master.cf – Modified to use Amavisd-New.

Important: Do not modify the Postfix configuration files directly! Some of the Postfix files are rewritten when changes are made in the administration console. Any changes you make will be overwritten.

MTA Functionality

Zimbra MTA Postfix functionality includes:

SMTP authentication
Attachment blocking
Relay host configuration
Postfix-LDAP integration
Integration with Amavisd-New, ClamAV, and Spam Assassin

SMTP Authentication

SMTP authentication allows authorized mail clients from external networks to relay messages through the Zimbra MTA. The user ID and password is sent to the MTA when the SMTP client sends mail so the MTA can verify if the user is allowed to relay mail.

Note: User authentication is provided through the Zimbra LDAP directory server, or if implemented, through the Microsoft Active Directory Sever.

SMTP Restrictions

In the administration console, you can enable restrictions so that messages are not accepted by Postfix when non-standard or other disapproved behavior is exhibited by an incoming SMTP client. These restrictions provide some protection against ill-behaved spam senders. By default, SMTP protocol violators (that is, clients that do not greet with a fully qualified domain name) are restricted. DNS based restrictions are also available.

Important: Understand the implications of these restrictions before you implement them. You may want to receive mail from people outside of your mail system, but those mail systems may be poorly implemented. You may have to compromise on these checks to accommodate them.

Relay Host Settings

Postfix can be configured to send all non-local mail to a different SMTP server. Such a destination SMTP server is commonly referred to as a “relay” or “smart” host. You can set this relay host from the administration console.

A common use case for a relay host is when an ISP requires that all your email be relayed through designated host, or if you have some filtering SMTP proxy server.

In the administration console, the relay host setting must not be confused with web mail MTA setting. Relay host is the MTA to which Postfix relays non-local email. Webmail MTA is used by the Zimbra server for composed messages and must be the location of the Postfix server in the Zimbra MTA package.

Important: Use caution when setting the relay host to prevent mail loops

MTA-LDAP Integration

The Zimbra LDAP directory service is used to look up email delivery addresses. The version of Postfix included with Zimbra is configured during the installation of the Zimbra Collaboration Suite to use the Zimbra LDAP directory.

Account Quota and the MTA

Account quota is the storage limit allowed for an account. Account quotas can be set by COS or per account. The MTA attempts to deliver a message, and if a Zimbra user’s mailbox exceeds the set quota, the Zimbra mailbox server rejects the message as mailbox is full and the sender gets a bounce message. You can view account quotas from the Administration Console, Monitoring Server Statistics section.

MTA and Amavisd-New Integration

The Amavisd-New utility is the interface between the Zimbra MTA and Clam AV and SpamAssassin scanners.

Anti-Virus Protection

Clam AntiVirus software is bundled with the Zimbra Collaboration Suite as the virus protection engine. The Clam anti-virus software is configured to block encrypted archives, to send notification to administrators when a virus has been found, and to send notification to recipients alerting that a mail message with a virus was not delivered.

The anti-virus protection is enabled during installation. You can also enable or disable virus checking from Global Settings on the administration console. By default, the Zimbra MTA checks every two hours for any new anti-virus updates from ClamAV.

Note: Updates are obtained via HTTP from the ClamAV website.

Anti-Spam Protection

SpamAssassin and DSPAM are spam filters bundled with ZCS. When ZCS is installed, spam training is automatically enabled to let users train spam filters when they move messages in and out of their junk folders.

The SpamAssassin default configuration for ZCS is as follows:

zimbraSpamKillPercent: Spaminess percentage beyond which a message is dropped. Default kill percent at 75%. Mail that is scored at 75% is considered spam and is not delivered. SpamAssassin score of 20 is considered 100%. 75% equates to a spam score of 15.
zimbraSpamTagPercent: Spaminess percentage beyond which a message is marked as spam. Default tag percent at 33%. Mail that is scored at 33% is considered spam and is delivered to the Junk folder. Since a SpamAssassin score of 20 equates to 100%, the zimbraSpamTagPercent would equate to a spam score of 6.6.

A Subject Prefix can be configured so messages considered as spam are identified in the subject line as tagged as spam. When a message is tagged as spam, the message is delivered to the recipient’s Junk folder.

You can change these settings from the administration console, Global Settings Anti-Spam tab.

Note: ZCS configures the spam filter to add 0.5 to the Spamassassin score if DSPAM marks the message as spam and deduct 0.1 if DSPAM does not label it as spam.

Anti-Spam Training Filters

When ZCS is installed, the automated spam training filter is enabled and two feedback mailboxes are created to receive mail notification.

Spam Training User to receive mail notification about mail that was not marked as junk, but should be.
Non-spam (HAM) training user to receive mail notification about mail that was marked as junk, but should not have been.

For these training accounts, the mailbox quota is disabled (i.e. set to 0) and attachment indexing is disabled. Disabling quotas prevents bouncing messages when the mailbox is full.

How well the anti-spam filter works depends on recognizing what is considered spam or not considered spam. The SpamAssassin filter can learn what is spam and what is not spam from messages that users specifically mark as Junk from their web client toolbar or Not Junk from the web client Junk folder. A copy of these marked messages is sent to the appropriate spam training mailbox.The Zimbra spam training tool, zmtrainsa, is configured to automatically retrieve these messages and train the spam filter.

The zmtrainsa script is enabled through a cron job to feed mail that has been classified as spam or as non-spam to the SpamAssassin application, allowing SpamAssassin to ‘learn’ what signs are likely to mean spam or ham. The zmtrainsa script empties these mailboxes each day.

By default all users can give feedback in this way. If you do not want users to train the spam filter, you can modify the global configuration attributes, zimbraSpamIsSpamAccount and zimbraSpamIsNotSpamAccount, and remove the spam/ham account addresses from the attributes. To remove, type as:

zmprov mcf <attribute> ‘’

Restart the Zimbra services, type zmcontrol stop and then zmcontrol start.

When these attributes are modified, messages marked as junk or not junk are not copied to the spam training mailboxes.

Initially, you may want to train the spam filter manually to quickly build a database of spam and non-spam tokens, words, or short character sequences that are commonly found in spam or ham. To do this, you can manually forward messages as message/rfc822 attachments to the spam and non-spam mailboxes. When zmtrainsa runs, these messages are used to teach the spam filter. Make sure you add a large enough sampling of messages to these mailboxes. In order to get accurate scores to determine whether to mark messages as spam at least 200 known spams and 200 known hams must be identified.

The zmtrainsa command can be run manually to forward any folder from any mailbox to the spam training mailboxes. To send a folder to the spam training mailbox, type the command as:

zmtrainsa <server> <user> <password> spam [foldername]

To send the to the non-spam training mailbox, type:

zmtrainsa <server> <user> <password> ham [foldername]

Password is not needed in 4.5.6+ see CLI_zmtrainsa

See Customizing the MTA for current information

Receiving and Sending Mail through Zimbra MTA

The Zimbra MTA delivers both the incoming and the outgoing mail messages. For outgoing mail, the Zimbra MTA determines the destination of the recipient address. If the destination host is local, the message is passed to the Zimbra server for delivery. If the destination host is a remote mail server, the Zimbra MTA must establish a communication method to transfer the message to the remote host. For incoming messages, the MTA must be able to accept connection requests from remote mail servers and receive messages for the local users.

In order to send and receive email, the Zimbra MTA must be configured in DNS with both an [B_app-glossary.16.1.html#1037278 A record] and a [B_app-glossary.16.1.html#1021370 MX Record]. For sending mail, the MTA use DNS to resolve hostnames and email-routing information. To receive mail, the MX record must be configured correctly to route messages to the mail server.

You must configure a relay host if you do not enable DNS. Even if a relay host is configured, an MX record is still required if the server is going to receive email from the internet.

Zimbra MTA Message Queues

When the Zimbra MTA receives mail, it routes the mail through a series of queues to manage delivery. The Zimbra MTA maintains four queues where mail is temporarily placed while being processed: incoming, active, deferred and hold.

6 MTA.5.1.2.jpg

Incoming.

The incoming message queue holds the new mail that has been received. Each message is identified with a unique file name. Messages in the incoming queue are moved to the active queue when there is room in the active queue. If there are no problems, message move through this queue very quickly.

Active.

The active message queue holds messages that are ready to be sent. The MTA sets a limit to the number of messages that can be in the active queue at any one time. From here, messages are moved to and from the anti-virus and anti-spam filters before being delivered or moved to another queue.

Deferred.

Message that cannot be delivered for some reason are placed in the deferred queue. The reasons for the delivery failures is documented in a file in the deferred queue. This queue is scanned frequently to resend the message. If the message cannot be sent after the set number of delivery attempts, the message fails. The message is bounced back to the original sender.

Microsoft Power Bi – Add image, text, video, and more to your dashboard

Add tile

The Add tile control lets you directly add an image, text box, video, streaming data, or web code to your dashboard.

  1. Select Add tile from the top menu bar. Depending on space limitations, you may see only the plus  sign.

  2. Select which type of tile to add: ImageText boxVideoWeb content, or Custom streaming data.

Add an image

Say you want your company logo on your dashboard, or some other image. You’ll need to save the image file online and link to it. Make sure special credentials aren’t required to access the image file. For example, OneDrive and SharePoint require authentication, so images stored there can’t be added to a dashboard this way.

  1. Select Image > Next.

  2. Add image information to the Tile details pane.

    • to display a title above the image, select Display title and subtitle and type a title and/or subtitle.
    • enter the image URL
    • to make the tile a hyperlink, select Set custom link and enter the URL. When colleagues click this image or title, they’ll be taken to this URL.
    • Select Apply. On the dashboard, resize and move the image as needed.

Add a text box or dashboard heading

  1. Select Text box > Next.

    NOTE: To add a dashboard heading, type your heading in the text box and increase the font.

  2. Format the text box:

    • to display a title above the text box, select Display title and subtitle and type a title and/or subtitle.
    • enter and format content for the text box.
    • Optionally, set a custom link for the title. However, in this example we’ve added hyperlinks within the text box itself, so leave Set custom link unchecked.
  3. Select Apply. On the dashboard, resize and move the text box as needed.

Add a video

When you add a YouTube or Vimeo video tile to your dashboard, the video plays right on your dashboard.

  1. Select Video > Next.

  2. Add video information to the Tile details pane.

    • to display a title and subtitle at the top of the video tile, select Display title and subtitle and type a title and/or subtitle. In this example, we’ll add a subtitle and then turn it into a hyperlink back to the entire playlist on YouTube.
    • enter the URL for the video
    • Add a hyperlink for the title and subtitle. Perhaps after your colleagues watch the embedded video you’d like them to view the entire playlist on YouTube — add a link to your playlist here.
    • Select Apply. On the dashboard, resize and move the video tile as needed.

  3. Select the video tile to play the video.

  4. Select the subtitle to visit the playlist on YouTube.

Add streaming data

Add web content

Paste or type in any HTML content. Power BI adds it, as a tile, to your dashboard. Enter the embed code by hand or copy/paste from sites such as Twitter, YouTube, embed.ly, and more.

  1. Select Web content > Next.

  2. Add information to the Add web content tile pane.

    • to display a title above the tile, select Display title and subtitle and type a title and/or subtitle.
    • enter the embed code. In this example we’re copying and pasting a Twitter feed.
    • Select Apply. On the dashboard, resize and move the web content tile as needed.

Tips for embedding web content

  • For iframes, use a secure source. If you enter your iframe embed code and get a blank tile, check to see if you’re using http for the iframe source. If so, change it to https.
  https://xyz.com

If you’d like the player to resize to fit the tile size, set width and height to 100%.

  
  • This code embeds a tweet and retains, as separate links on the dashboard, links for the AFK podcast, @GuyInACube’s Twitter pageFollow#analyticsreplyretweet, and like. Selecting the tile itself takes you to the podcast on Twitter.
  <blockquote class="twitter-tweet" data-partner="tweetdeck">
  <p lang="en" dir="ltr">Listen to
  <a href="https://twitter.com/GuyInACube">@GuyInACube</a> talk to
  us about making videos about Microsoft Business Intelligence
  platform

Edit a tile

To make changes to a tile…

  1. Hover over the top right corner of the tile and select the ellipses.

  2. Select the edit icon to re-open the Tile details pane and make changes.

Considerations and troubleshooting

  • To make it easier to move the tile on your dashboard, add a title and/or subtitle.

  • If you’d like to embed some content from a website, but the website doesn’t give you embed code to copy and paste, check out embed.ly for help generating the embed code.

How to migrate a Windows PC to a Parallels Desktop virtual machine

Symptoms

You have a Windows PC, and you want to migrate it, along with all its content, to a Parallels Desktop for Mac virtual machine.

Resolution

You can import all your data from a Windows PC to Parallels Desktop on your Mac. Then you can continue to work with all your Windows programs, files, and data side-by-side with OS X.

Important: After importing your data from your PC, you may need to reactivate some of your Windows programs using the activation keys you received when you purchased the programs.


Note: After migration is complete your PC will remain unmodified. See related article KB 117639


Requirements for importing your data

To import data to your Mac, you need a Windows computer with the following specifications:

  • Windows XP with Service Pack 2 or later, Windows Vista, Windows 7 or Windows 8.

    Note: You can also use a computer running Windows Server 2008 R2 (64-bit only), Windows Server 2008, or Windows 2000 Professional (32-bit only).

  • An Intel or AMD (700 MHz or higher) x86 or x64 processor
  • At least 256 MB of RAM
  • At least 70 MB of hard disk space for installing Parallels Transporter Agent
  • One of the following:
    • An Ethernet port for transferring your data over the network
    • A USB port for transferring your data using the Parallels USB cable
  • An external storage device, such as a USB hard disk
  • Supported Windows and Linux versions:**

Also read KB #119172 before proceeding with migration.

Step 1: Install Parallels Transporter Agent on your Windows PC

To import your data, you must first install the Parallels Transporter Agent software on the Windows PC.
