One part of the company is Return to Remarketing, where devices delivered to the technology center (notebooks, smartphones, tablets, etc.) are prepared for resale. The project I supported was responsible for enabling damage assessment of returned lease devices, documenting them visually in the form of pictures, enabling invoicing for the customer, and making the pictures available via the in-house customer platform. This was achieved through a combination of in-house development within the internal development department and the use of SaaS products. The second project was the transition of SaaS tendering software, purchased by the business unit, into the operations of the CHG IT department. Evaluation of security questions in relation to BaFin requirements, development of an authorization concept, implementation of single sign-on, documentation of the application in the CHG systems (CMDB, iKnow, etc.) and handover into operations.

About the technology
Microsoft Windows at a glance
Microsoft Windows is the standard desktop and server operating system in many company environments. It is used to run office workstations, line-of-business software, and managed corporate devices. Strong experts know how Windows behaves on the endpoint and inside a wider domain setup.
Typical work
- New device setup and image preparation
- Windows 10 and Windows 11 migrations
- Windows Server administration and patching
- Active Directory, Group Policy, and access control
- Troubleshooting login, update, and driver issues
Ecosystem and tools
Windows work often touches Microsoft 365, Intune, SCCM, Hyper-V, PowerShell, and Remote Desktop Services. In larger setups, specialists also coordinate with Entra ID, file services, print services, and endpoint protection. Good professionals understand how these parts interact without creating conflict in the environment.
When companies bring in freelancers
Companies usually look for outside help when a rollout needs extra hands, when legacy apps must keep running, or when a migration carries too much operational risk for the internal team. In Essen, this is common for offices, industrial sites, and service teams that need reliable support without long delays. Freelancers can step in for short projects or on-site work.
What strong specialists do
A strong Microsoft Windows professional documents changes clearly, tests before release, and keeps recovery paths ready. They understand user profiles, security baselines, permissions, and update rings. They also know when to fix a symptom and when to trace the real cause in policy, hardware, or software compatibility.
Remote and on-site support
Windows projects can often be handled remotely, especially for policy changes, software deployment, and user support. On-site work is still valuable for hardware issues, local network faults, and hands-on rollout support. For Essen teams, the best setup is often a mix of remote planning and local execution when needed.
Frequently asked questions
Quick answers to the questions that come up most around Microsoft Windows.
Microsoft Windows is the operating system behind most office PCs and many internal business systems. Companies use it for daily work, access to shared files, line-of-business apps, domain login, and managed device control. In larger environments, it also supports server roles such as authentication, remote access, and file services.
Windows is the general name for the desktop operating system, while Windows Server is the server-focused product line. They share tools, admin concepts, and a similar interface, but they serve different roles. A freelancer should know both if the project includes domain services, remote desktops, or server maintenance.
Microsoft Windows work is a good fit for outside help when the task is time-sensitive, high risk, or too broad for the internal team. Typical cases are migrations, Group Policy cleanup, endpoint standardization, and hard-to-trace login or update problems. Freelancers are also useful when you need focused support without adding permanent headcount.
A strong Microsoft Windows freelancer usually brings PowerShell, Active Directory, and Microsoft 365 knowledge. Depending on the project, Intune, SCCM, Hyper-V, and security hardening can matter just as much. For server-heavy work, backup, networking, and permission design are also important.
Microsoft Windows is usually preferred where standard office workflows, Microsoft software, and domain-managed endpoints are central. Linux is often chosen for server stacks, automation, or custom infrastructure. Many companies use both, so the best freelancer understands where Windows fits and where another system is the better choice.
For Windows support tickets or small configuration tasks, a broad generalist may be enough. For migrations, access control, or endpoint rollout work, you want someone who has handled similar environments before. The more users, devices, or servers involved, the more important proven project experience becomes.
Many Microsoft Windows tasks can be done remotely, including policy changes, software deployment, and troubleshooting. On-site support is better for hardware failures, local network issues, and device handover. For Essen-based teams, a hybrid setup often works well when users are local but admin work can stay remote.
A strong Windows specialist explains problems clearly, documents changes, and checks for side effects before making updates. Look for practical experience with Group Policy, PowerShell, patch management, and recovery planning. Good candidates also ask about your device mix, security rules, and existing Microsoft services before they start.
