Some Methods:

Start Windows using Last Known Good Configuration. If you’ve just made a change to your computer that you suspect might have caused Windows to stop booting properly, starting with the Last Known Good Configuration could help.

Start Windows in Safe Mode and then use System Restore to undo recent changes. Windows could freeze, stop, or reboot during the startup process because of damage to a driver, important file, or part of the registry. A System Restore will return all of those things to their last working order which could solve your problem entirely. You can also start a command prompt from the System Repair dialog box.

For Windows 7: Boot from the repair disk > Choose keyboard and click Next > Use recovery tools… and click Next > Windows may find problems fix them and reboot, if it works great. If it didn’t work or it didn’t find problems continue on > choose Command Prompt

For Windows 8, Windows 10, Windows 2012 R2: Boot from repair disc > Choose Keyboard type > click Troubleshoot > click Advanced options > choose Automatic Repair

if that fails then use:

-Boot from Recovery disc or Install disc

-Boot from repair disc > Chose Keyboard type > click Troubleshoot > click Advanced options > choose Command Prompt

or

-Boot from Install disc > Click Next > click Repair your computer > click Troubleshoot > click Advanced options > choose Command Prompt

    bootrec /scanos (scans for other OS’s that you might want to add to bcd)
    bootrec /rebuildbcd (scans for other OS’s, unlike rebuildbcd it allows you to select the OS’s you want to add to bcd)

Also: Emergency repair disk (ERD) from the MDOP (but requires the software assurance – more for larger companies)

Disabling SMB v1 (lanmanserver “server service only”) on windows computers/servers:

Full version: https://blogs.technet.microsoft.com/staysafe/2017/05/17/disable-smb-v1-in-managed-environments-with-ad-group-policy/

 

My recommendation:

a) for domain-based computers: use GPO “group policy object” to deploy the registry key to disable SMBv1 (server-side only) protocol on all systems (A reboot is required to take effect)

 

b) for isolated computer or non/domain joined computers: use the following command line to modify the lanmanserver registry key properly

 

Implementation – Technical details:

 

a) for domain-based computers, create a GPO or modify an existing GPO applied to computers only, to add the following registry key:

 

for domain-based computers, to create the GPO setting to disable SMB v1, use GPMC, Computer configuration, preferences, windows settings, registry, right-click, new registry item,

 

keep: Update,

Select the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters

 

Value: SMB1

Data: REG_DWORD 0

 

Note: To re-enable it

REG_DWORD: 1 = Enabled

Default: 1 = Enabled

 

 

b) for isolated computer or non/domain joined computers:

 

b.1) For Windows 8 and Windows server 2012 or greater (Note: not supported on Windows 7):

To obtain the current state of the SMB server protocol configuration, run the following cmdlet:

 

Get-SmbServerConfiguration | Select EnableSMB1Protocol

 

To disable SMBv1 on the SMB server, run the following cmdlet:

 

Set-SmbServerConfiguration -EnableSMB1Protocol $false

 

b.2) For Windows 7, Windows Server 2008 R2, Windows Vista, and Windows Server 2008

 

To enable or disable SMB protocols on an SMB Server that is running Windows 7, Windows Server 2008 R2, Windows Vista, or Windows Server

2008, use Windows PowerShell or Registry Editor.

 

To disable SMBv1 on the SMB server, run the following cmdlet:

 

Set-ItemProperty –Path “HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters” SMB1 -Type DWORD -Value 0 –Force

 

To assess the impact:

 

This article contain a table to understand what version you will end up, depending on what Windows version is running as the SMB client and what version of Windows is running as the SMB server.

A patch that was released in March protects your organization from “WannaCry” and similar variants, you should immediately deploy it if you haven’t: https://technet.microsoft.com/en-us/library/security/ms17-010.aspx

“Additionally, we are taking the highly unusual step of providing a security update for all customers to protect Windows platforms that are in custom support only, including Windows XP, Windows 8, and Windows Server 2003”

Here are resources about Azure and Office365,

let me summarize:

Office365 : is an offer of MS services and hosted applications – Saas ; in clear you pay for a service (sharepoint,exchange,office…) and you don’t manage the infra behind (like CPU,RAM,Storage,Security)

Azure: is a cloud (private/public) offer – paas/Iaas ; compared to Office365, MS provide just the plumbery (hyper-v, Storage, CPU, RAM, network) and you manage the applications, the Operating system, the security and patches, the applications ; in short “it is like a lego or a Mecano!”, and with Azure you can mix your on-premises IT infra with Azure in the cloud (and vice-versa)

Prerequisites before using Azure:

Prepare your environment: http://msdn.microsoft.com/en-us/library/windowsazure/jj554332.aspx

Need certificates: http://msdn.microsoft.com/en-us/library/windowsazure/gg981929.aspx

How to use CSUpload?

How do you get CSUPLOAD?

CSUPLOAD is part of the Windows Azure SDK. After installing all components, it finds you csupload under the following path:
“C:\Program Files\Microsoft SDKs\Windows Azure\.NET SDK\v2.0\bin\csupload.exe”
How does CSUPLOAD work?

CSUPLOAD is a command console program that the VHDs in the uploads BLOB storage account and authenticated to the azure cloud client certificates.
Overall it with Visual Studio is very simple and fast to create the appropriate certificates, and to distribute them to the appropriate locations through the function
“Publish to Azure” that requires requires developer know-how or you experience with the Visual Studio.

CSUpload syntax reference:

the article above refers to: http://www.microsofttranslator.com/bv.aspx?from=&to=en&a=http%3A%2F%2Fblogs.msdn.com%2Fb%2Favkashchauhan%2Farchive%2F2011%2F09%2F21%2Fhow-to-generate-2048-bit-certificate-with-makecert-exe.aspx

Example:

CSUPLOAD how to?

# Create exportable certificate for Azure (use -pe to be exportable)
makecert -r -pe -n “CN=My Azure IaaS Cert2048” -a sha1 -ss My -len 2048 -sy 24 -b 07/08/2013 -e 07/08/2014

then open mmc,load certificates snap-in, My user, personal,
select the certificate, export
to D:\Contoso
MyAzureCertificate.cer

upload the certificate, from the Azure portal, settings, certificates management

get the thumbprint: 4D15540AFD7182964651826BE133FB3C868BA4D1

Now with csupload:

“C:\Program Files\Microsoft SDKs\Windows Azure\.NET SDK\v2.0\bin\csupload” Set-Connection “SubscriptionId=eaea9c22-cc5a-4da2-8dd2-d89837f042b7;CertificateThumbprint=4D15540AFD7182964651826BE133FB3C868BA4D1;ServiceManagementEndpoint=https://management.core.windows.net”

Upload a disk (vhd) to Azure:

You can use the Add-Disk parameter of the CSUpload Command-Line Tool to upload a .vhd file and register it in Windows Azure as either an operating system disk or a data disk.
An image is a VHD that has been generalized and is used to create an operating system disk. An operating system disk is a VHD that contains specific settings for a virtual machine.

Specifies a VHD file to be uploaded as a disk. A VHD file that has been uploaded as a disk can be used to create a virtual machine if the file contains an operating system or it can be used to create a data disk that can be attached to a virtual machine.
•–Connection <string> – (Optional if the Set-Connection command has been run) Specifies the connection string that is used to connect to Windows Azure. The connection string contains the identifier of your Windows Azure subscription and the thumbprint of the management certificate that you created to enable API access to the subscription. The connection string is provided in the following format: “SubscriptionID=subscription-id;CertificateThumbprint=cert-thumbprint;ServiceManagementEndpoint=https://management.core.windows.net”. You can find the subscription identifier and certificate thumbprint in Management Portal.
•-Destination <string> – Specifies the blob storage account where the VHD file is stored. The destination includes the endpoint of the account, the container in the account where the file is stored, and the name of the VHD file. For example,”http://auxpreview146imagestore.blob.core.azure-preview.com/mydisks/mydisk.vhd&#8221;
•-Label <string> – Specifies the identifier that is used for the disk in the Management Portal.
•-LiteralPath <string> – Specifies the location and name of the VHD file to upload as a disk.
•-Name <string> – (Optional) Specifies the name to be used for the VHD file that is being uploaded.
•-OS <string> – (Optional) If the VHD file that is being uploaded contains an operating system to be used with a virtual machine, you must include this parameter with the value of Windows or Linux depending on the type of operating system that is installed.
•-Overwrite – (Optional) Indicates that you intend to overwrite an existing VHD file with a new file.
