Mobile - AdBlock - Block ads from all browsers #android

Using Chrome on Android mobile phone advertisement, unwanted pop-ups, video ads, banners and so on creates several problems during normal browsing activities.

Today I searched on play store and I found an interesting app (AdBlock), for free, that creates VPN connection (*), that blocks several adv types, helps to block spyware, adware and malware (not loading infected domains) and connecting to other adv/AV Database websites that helps to block adv and malicious websites

(*) One Key functionality intercepts DNS traffic

It works very well and there is a plus version that is quite cheap.

In contrast to other ad blockers, AdBlock doesn't require root access.

Backup - Veeam Agent for Microsoft Windows/Linux 3.0

During previously years I already wrote some blogs posts about Veeam Agent for Windows/Linux.

Veeam - Veeam Endpoint Backup Free - Free version released
Backup - Veeam Backup for free v.2.0 for Client/Laptop

It is a very interesting backup software that permit to schedule bare metal backups for physical clients and Servers.
Backups can be done to external Hard Drives, NAS, shares, cloud or to Veeam B&R repositories.

There are 3 versions (Windows Product Edition Comparison - Linux Product Edition Comparison):

  1. Free. (no VSS, limitations about scheduling &Targets repositories, retention, Veeam B&R integration and technical support)
  2. Workstation. (no VSS, limitations about scheduling, retention, B&R integration)
  3. Server: that permit centralized Endpoint backup managements from Veeam B&R console (excellent feature)

Here they are some applicative aspects with relative hyperlinks:

  • Backup & Restore features.
  • Bare-metal restore & Bootable recovery media creation.
  • Backups with passwords.
  • Additional features:
    • Password Reset about built-in Administrator account.
    • Startup repair.
    • Memory diagnostics.
Here it is Veeam Agent For Microsoft Windows Datasheet for which I highlight some interesting features:

TIPS - rotated drives with Veeam Agent Windows - Free mode

Latter part of this article is dedicated to feature that is available with free edition:

Backup on rotated drives is performed in the following way:

1. Veeam Agent for Microsoft Windows creates a backup chain on an external drive that you use as a backup target. The backup chain consists of the first full backup and a set of subsequent incremental backups.

2. When you swap drives and attach a new external drive, Veeam Agent for Microsoft Windows creates a separate backup chain on the new drive.

3. After you swap drives again, Veeam Agent for Microsoft Windows detects if there is a backup chain on the currently attached drive. If the backup chain exists, Veeam Agent for Microsoft Windows continues the existing chain: it creates a new incremental backup file and adds it to the existing backup files."

Here it is Veeam article and few screenshots for configuration:


Here it is an interesting Veeam Article that explains differences between Synthetic vs Full backup

"In free mode you can create only a single scheduling but you can use rotated drives as a target location for backups. This scenario can be helpful if you want to store backups on several external hard drives (for example, USB or FireWire) and plan to swap these drives between different locations regularly.

Windows 10 - How to install RSAT on version 1809

In previous old blog article I already discussed about RSAT installation procedure.:

Secondly I pointed opportunity to manage server only from your workstation/client executing all server plugin avoiding to connect to each server via RDP (security aspect) and having a single point of management with all rsat tools.

With new Windows 10 version (1809) something changed slightly.

Here it is powershell installation procedure:

In any case there are other alternative procedure to get same result:
  1. Execute Windows Powershell with administrative rights and launch this command to verify that no RSAT tool is really installed
    Get-WindowsCapability -Name RSAT* -Online
  2. Using below command information would be formatted in a more readable way:

    Get-WindowsCapability -Name RSAT* -Online | Select-Object -Property DisplayName, State
  3. To add a single tool you should use below syntax:

    Add-WindowsCapability –online –Name “Rsat.ActiveDirectory.DS-LDS.Tools~~~~
  4. To add all available Rsat tools this is syntax correct:
    Get-WindowsCapability -Name Rsat* -Online | Add-WindowsCapability –Online
  5. To install only disabled RSAT components, run:

    Get-WindowsCapability -Online |? {$_.Name -like "*Rsat*" -and $_.State -eq "NotPresent"} | Add-WindowsCapability -Online
  6. If you got below error it should be due to Wsus internal server pointing:

    Add-WindowsCapability : Add-WindowsCapability failed. Error code = 0x800f0954
  7. In this case you should execute 

    Changing  UseWUServer key to 0 and restarting Windows update service.

    Restart-Service wuauserv

    And then launching this command:

    Get-WindowsCapability -Name Rsat* -Online | Add-WindowsCapability –Online
    Afterward rollback previously UseWUServer key value and restarting Windows update service

    Restart-Service wuauserv
  8. You could execute below powershell command:
  • $currentWU = Get-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU" -Name "UseWUServer" | select -ExpandProperty UseWUServer
  • Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU" -Name "UseWUServer" -Value 0
  • Restart-Service wuauserv
  • Get-WindowsCapability -Name RSAT* -Online | Add-WindowsCapability –Online
  • Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU" -Name "UseWUServer" -Value $currentWU
  • Restart-Service wuauserv

Tips - Live Optics and Vmware 5.1.0 No SOAP response error

Live Optics permits collecting all Hypervisors and VM performance counters.

Live Optics (Dell EMC) is an industry standard method of impartially documenting server/storage configuration and performance as well as observing file characteristics of data. 

This approach permits to analyse existing infrastructure and help decisions about upgrade or hardware renewal as well.

Consider that SAN Optics can be utilized to conduct health assessments on your Storage Area Networks. 

Here it isproblem that we faced (and succesfully fixed):

  • We executed Live Optics software on a W2008 R2 Server related to a Vmware vCenter Server 5.1.0.
  • Collecting was not working using administrator account as well.
  • "LiveOptics_TroubleshootingTrace.txt" was showing these entries

Tips - Sitemap creation hosted BLOGGER web sites

Today I was working on google search console and I was surprised that only few pages was indexed, searching on internet I found problem resolution and applied some fixes.

Furthermore you may find more technical details and relative workflow.


  • Sitemap file functionality is used mentioning all website pages, unfortunately this is not true for websites hosted on blogger environments.

  • Default blogger XML file refers only to 26 most recent articles.

  • Consequential limitation is easy to be understood (for search engine websites visibility and indexing first)

  • You might override this limitation going to this website, indicate your website, get XML text and insert it in your blogger administration console ( Settings – > Search Preferences, the enable Custom robots.txt option (available in the Crawling and Indexing section).

In this way all search engines will discover your XML sitemap and indexing at all.

Here they are some screenshots
