Restore a machine with a UEFI BIOS and GPT system partition

In the Recovery Environment: 

      1. UEFI machines vary in their ability to support booting off  of a legacy (MBR format) CD or USB flash drive.  Motherboard manufacturers do not always maintain the same naming conventions or options for their UEFI capable motherboards. There may need to be changes made in the machine's UEFI BIOS.   Some of the newer BIOS's will support booting off a CD without BIOS changes.  
        • In the UEFI, the BIOS option needs to be set to Legacy or compatibility mode.
          (The wording and options can be different with each manufacturer).  
        • After the restore completes, change the mode back. 
          • Once booted into the Recovery Environment,  convert the system disk to a GPT partition. 
      2. Right click on the disk and select "Convert to GPT disk"
        • If the  "Convert to MBR disk" is the only option, convert the disk to MBR, then again, back to GPT.  This ensures that the disk is correctly configured to GPT by the Recovery Environment.
      3. The Disk Signature window will show after the disk is converted to GPT format.
      4. Select OK to set the defaults when creating a system disk.
      5. Once the Recovery Environment configures the disk as GPT, there will be three partitions: 
        • System
        • UEFI
        • The partition for the OS restore 
      6. The space will not be allocated to the partition.  To do this, create a partition size that is the same size or larger than the OS being restored.  
        • If the partition is smaller than the backup see this KB article.
      7. The only option that will be different in a UEFI\GPT restore is for the MBR and track Zero options.  
        • Since it is not an MBR restore, these are greyed out.
      8. If this restore is to different hardware from the backup, select to use the "Hardware Independent Restore" option.
      9. Once the restore is done, verify, with the "Boot Configuration Utility" tool, that the machine reports as bootable.  
        • If the boot is broken,  then select the auto repair step to correctly configure the machine to boot.
Once restored, if there were settings in the BIOS changed to boot off the Recovery Environment,  change them back before booting to the OS.

Check Windows Firewall status with netsh advfirewall show allprofiles

Check Windows Firewall status with netsh advfirewall show allprofiles   It is important to know what type of firewall connection each user in your network has. If users are connected to the Internet, they have a public profile. If they are connected to an internal network they have a private profile. And if they're connected to a corporate network, they have a domain profile. You can use netsh advfirewall show allprofiles to identify what type of profile a user has. On remote computers, you have to use netsh -r computername advfirewall show allprofiles and the user must turn on remote registry access for the command to work. To turn off the firewall for every profile no matter the connection type, you can use netsh advfirewall set allprofiles state off . If you want to turn on the firewall for remote computers with a public profile you can use netsh -r computername advfirewall set publicprofile state on . In addition, you can turn off the remote computer's firewal...

3 Solutions after Accidentally Marking Drive C Active

Several months ago, one of my friends told me that his Windows operating system cannot boot after he accidentally marked drive C active, and I finally helped him fix the issue after a series of researches. Several days ago, when I was browsing a famous Windows related forum, the same question was found, and till now it hasn't been resolved. Therefore, I plan to write this post, hoping it useful and helpful for users who are troubled by the same issue. My post contains 3 parts, including which partition should be set active, why this partition should be set active, and how to set the correct partition active. Next, let's see these parts one by one. Which Partition Should Be Set Active Before answering this question, we need to know something about system partition and boot partition, because both of them play significant roles in booting Windows. As loading architecture of Windows OS changed a lot since Windows Vista, here we just take Windows Vista for exampl...

Query the status of services with sc query state= all

Query the status of services with sc query state= all   Anytime you want to know what services are installed on a computer and find out which ones are active, you can use sc query state= all to find a complete list. If the computer in question is remote, you should use sc \\computername query state= all . If you're looking for a specific service, you can use sc query service_name . To find the configuration information for a specific service, you can use sc qc service_name . To stop a particular service from running on a computer, use sc \\computername stop service_name . And if you have to start a service on a computer, you can use sc \\computername start service_name . Another query command that can come in handy if, for example, you have to see the results of a security audit is auditpol /get /category:* .With this command, you can ask for and establish audit settings on a local computer.  To see the same results in CSV format you can use auditpol /get /catego...
