Practical guides for system administrators — Windows, PowerShell, Active Directory, networking, and infrastructure.
Windows Terminal lets you define color schemes once in settings.json and apply them to any profile. For administrators who spend hours reading PowerShell output, event logs, and SSH sessions, a well-configured scheme is not cosmetic — it directly affects how…
Many games store save files in a fixed local path with no built-in cloud sync option. If you reinstall Windows, switch machines, or simply want an automatic backup of your progress, the standard workaround is to move the save folder…
Some applications write gigabytes of cache, logs, and profile data to C:\Users\John\AppData — with no built-in option to change that location. On systems with a small SSD boot drive, this fills up quickly. The standard solution is to move the…
Symbolic links and junctions are invisible in normal directory listings — they appear as regular folders or files in File Explorer and most tools. When auditing a system, troubleshooting a broken path, or reviewing a server you inherited, knowing where…
Windows supports three distinct types of filesystem links: symbolic links, directory junctions, and hard links. They look similar from the outside but behave differently in ways that matter — across drives, across reboots, under backup software, and under deletion. This…
Deleting a symbolic link or junction on Windows is not the same as deleting a regular folder — and using the wrong command will remove the target data, not just the link. This is one of the most common and…
PowerShell can encode and decode Base64 natively using the [Convert] .NET class — no external utilities, no temporary files with PEM headers. Unlike certutil, PowerShell produces clean RFC 4648 Base64 that is directly compatible with web APIs, Linux systems, and…
When you try to delete a local user account on a Windows computer joined to a domain, you may see a warning that stops many administrators in their tracks. The message warns that deleting the account will permanently remove a…
After making changes to your storage infrastructure — adding a new LUN, modifying iSCSI or Fibre Channel zoning, connecting a new NAS share, or removing a stale datastore — ESXi hosts do not automatically detect the updated storage state. A…
When a datastore loses its backend storage connection, vCenter can keep it registered in its inventory even though the underlying volume is no longer accessible. The GUI unmount task fails with a “datastore in use” error, and the ESXi host…
