SMB or Server Message Block Protocols are used to connect your computer to an external server. Windows 10 ships with support of these protocols but they are disabled in the OOBE. Currently, Windows 10 supports SMBv1, SMBv2, and SMBv3 as well. Different servers depending upon their configuration require a different version of SMB to get connected to a computer. But in case you are using Windows 8.1 or Windows 7, you can check if you have it enabled too. That’s what we are going to do today.

First of all, if you have Windows 7, you should not be disabling SMB v2. This is due to the following reasons:
- Request compounding – allows for sending multiple SMB 2 requests as a single network request
- Larger reads and writes – better use of faster networks
- Caching of folder and file properties – clients keep local copies of folders and files
- Durable handles – allow for connection to transparently reconnect to the server if there is a temporary disconnection
- Improved message signing – HMAC SHA-256 replaces MD5 as the hashing algorithm
- Improved scalability for file sharing – the number of users, shares, and open files per server greatly increased
- Support for symbolic links
- Client oplock leasing model – limits the data transferred between the client and server, improving performance on high-latency networks and increasing SMB server scalability
- Large MTU support – for full use of 10-gigabyte (GB) Ethernet
- Improved energy efficiency – clients that have open files to a server can sleep.

Even if you are on Windows 8.1 or Windows 10, you should not be disabling SMB v3 or SMB v2 because, in addition to the above problems, you might face the following issues too which come with disabling SMB v3:
- Transparent Failover – clients reconnect without interruption to cluster nodes during maintenance or failover
- Scale Out – concurrent access to shared data on all file cluster nodes
- Multichannel – aggregation of network bandwidth and fault tolerance if multiple paths are available between client and server
- SMB Direct – adds RDMA networking support for very high performance, with low latency and low CPU utilization
- Encryption – Provides end-to-end encryption and protects from eavesdropping on untrustworthy networks
- Directory Leasing – Improves application response times in branch offices through caching
- Performance Optimizations – optimizations for small random read/write I/O.
