What it does
Windows Registry is an agent skill from taracodlabs/aiden. Read, write, query Windows Registry via PowerShell provider
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `skill.json`).
It works with PowerShell. The repository describes itself as: Aiden — an autonomous AI agent and work engine built solo. It can operate your browser, terminal, files, apps, APIs, skills and tools, remember context, recover from failures… The licence is Apache-2.0.
Example prompts
- “/windows-registry”
What it can do on your machine
Read from SKILL.md and the folder at commit 3704204. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are powershell).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Windows Registry loads about 858 tokens when it runs. Until then it costs about 19 tokens; SKILL.md has 260 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Windows Registry
Read and write Windows Registry keys and values using PowerShell's built-in Registry provider — inspect startup entries, app settings, and system configuration without regedit.
When to Use
- User wants to read a registry value (e.g., installed software, startup entries)
- User asks to create or modify a registry key or value
- User wants to list all values under a registry path
- User needs to check what programs run at Windows startup
- User asks to remove a registry value or key
How to Use
Read a single registry value
Get-ItemPropertyValue -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Explorer" `
-Name "ShellState"List all values under a key
Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion"Check startup programs (current user and all users)
# Current user only
Get-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Run"
# All users (machine-wide)
Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Run"Create a new registry key
New-Item -Path "HKCU:\Software\Aiden" -ForceSet a registry value (string)
Set-ItemProperty -Path "HKCU:\Software\Aiden" -Name "Version" -Value "3.5.0" -Type StringSet a registry value (DWORD)
Set-ItemProperty -Path "HKCU:\Software\Aiden" -Name "Enabled" -Value 1 -Type DWordDelete a registry value
Remove-ItemProperty -Path "HKCU:\Software\Aiden" -Name "OldSetting"Delete a registry key and all subkeys
Remove-Item -Path "HKCU:\Software\Aiden" -Recurse -ForceSearch registry for a value name
Get-ChildItem -Path "HKLM:\SOFTWARE" -Recurse -ErrorAction SilentlyContinue |
Where-Object { $_.Property -contains "DisplayName" } |
Get-ItemProperty |
Select-Object DisplayName, DisplayVersion, Publisher |
Sort-Object DisplayNameList installed software
Get-ItemProperty "HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\*" |
Select-Object DisplayName, DisplayVersion, Publisher, InstallDate |
Where-Object DisplayName |
Sort-Object DisplayNameExamples
"What programs launch at startup for my user?"
→ Get-ItemProperty -Path "HKCU:\Software\Microsoft\Windows\CurrentVersion\Run" — each value name is an entry, value data is the command.
"List all installed software with version numbers" → Query both HKLM and HKCU Uninstall keys and merge results.
"Add a registry entry to run a script at login"
→ Set-ItemProperty -Path "HKCU:\...\Run" -Name "MyScript" -Value "powershell.exe -File C:\scripts\login.ps1"
Cautions
- Modifying HKLM keys requires an elevated session (UAC dialog) — HKCU keys do not
- Always read a key before modifying it to understand the current state
- Deleting registry keys is permanent — there is no Recycle Bin for registry changes
- Back up a key before editing:
reg export "HKCU\Software\Aiden" C:\backup\aiden-backup.reg - Registry paths in PowerShell use
\as separator (not/) and hive aliases likeHKCU:andHKLM:
