I have a strange issue on a customers VMware host. I have a guest OS (Windows SBS 2011) which should read Windows Server 2008 R2. It does wen the guest is powered off but when the guest is powered on it reads Windows 7 64 Bit. Everything seems to work fine. <br />
<br />
2 Questions. <br />
<br />
1 Should I be concerned? <br />
2 Is there a reason it might do this. <br />
<br />
<b>Notes:</b><br />
Original ESXi 4.1<br />
Install new (not update) ESXi 5.1 U1 with VMFS 5 now. Wiped the datasore and reformatted VMFS 5 then moved the VM's back.

Guest OS reads different when power on in vCenter

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.
