When the normal VMware Tools uninstaller is missing or broken, this script tears out every orphaned registry key, file, and service it left behind — walking every UserData SID (not just SYSTEM), de-duplicating multiple leftover installer entries, and matching services that don't even have "VMware" in their display name. Essential cleanup before a VMware-to-Hyper-V or other hypervisor migration.

Export Org and Org VDC capacity — CPU, RAM and per-storage-profile usage — across your entire VMware Cloud Director estate with one PowerCLI script. Covers a three-tier fallback for when the StorageProfiles property won't hydrate, a Search-Cloud query workaround, and the classic comma-vs-period decimal bug in Out-GridView.

A practical step-by-step guide to performing a Windows Server in-place upgrade on Azure VMs — covering disk resizing, snapshot rollback, upgrade media disk creation, boot diagnostics monitoring, and post-upgrade validation.

Learn how to use Azure Automation Runbooks to schedule tasks, start/stop VMs, and orchestrate complex workflows using PowerShell 7.4 and Managed Identity — no stored credentials required.

Deleting an organisation in VMware Cloud Director 10.4.x–10.6.x fails with a port profiles error? This is a known VCD bug. Learn how to force-delete the organisation via the built-in API Explorer and re-sync NSX-T application port profiles — no Broadcom support call required.

Replaced the HTTPS certificate in VMware Cloud Director 10.6.1 following Broadcom KB 379244 — everything looked fine until VM console access broke days later. Here's the undocumented step under Administration → Public Addresses that fixes it.

A practical guide to configuring Dell PowerEdge R660 BIOS settings at scale using the iDRAC Redfish REST API — no manual console access required. Covers authentication, reading current BIOS attributes, pushing configuration changes, and scheduling a reboot to apply settings.

A complete guide to implementing JML automation using PowerShell and the Microsoft Graph API for Azure Entra ID.

Automatically scan all App Registrations for expiring secrets and certificates using a Managed Identity — no stored credentials, no Office 365 licence required.

Update UserVars.ProductLockerLocation across all ESXi hosts in a vCenter cluster via the vSphere AdvancedOption API. Point hosts to a shared datastore path so VMs always pick up the latest VMware Tools automatically on restart.

Stop clicking through wizards. One Jenkins parameterised build provisions a complete vSphere VM — CPU, RAM, up to five disks, static IP, DNS, hostname — in under 10 minutes. Covers the script, Jenkins CI setup, and GitHub SCM integration for Continuous Delivery.

Stop manually resizing VMs in vCenter. A Jenkins Parameterised Build powered by PowerShell & PowerCLI safely shuts down, resizes CPU and/or Memory, verifies the change, and powers the VM back on — with a full audit trail and email alerting across PROD and DR vCenter environments.

Stop chasing snapshots manually. A Jenkins Parameterised Build powered by PowerCLI scans your Prod and DR vCenters on a cron schedule, exports a timestamped CSV report, and fires an automated email alert with the attachment — all with zero hardcoded credentials.

Eliminate manual vCenter sessions. A Jenkins Parameterised Build powered by PowerCLI expands up to five VMDK disks, optionally creates a new disk, and validates datastore free space before making any change — with a full audit trail across Prod and DR vCenter environments.

Audit every disk, CPU, and memory reconfiguration across your PROD and DR vCenters using the vSphere Task & Event Manager APIs. A Jenkins scheduled pipeline exports timestamped CSV reports and emails them to your ops team automatically — with zero hardcoded credentials.
