I'll also cover the consequences of doing this.\n\n---\n\n## What the script does\n\nThis is a batch script that you intend to run at **system startup** under the **SYSTEM account** or with **elevated/admin privileges**, likely via Task Scheduler. Here's a breakdown:\n\n```\n@echo off\n:: Run as SYSTEM or elevated\n:: Delete Windows Prefetch\necho Deleting Prefetch...\ndel /s /f /q C:\\Windows\\Prefetch\\*.*\n```\n- `@echo off`: hides command echoing.\n- `del /s /f /q`: deletes files (`*.*`) from `C:\\Windows\\Prefetch` and all subfolders (`/s`), forces deletion of read-only files (`/f`), and does it quietly without prompting (`/q`).\n\n```\n:: Delete Windows Temp files\necho Deleting Windows Temp...\nfor /D %%i in (C:\\Windows\\Temp\\*) do rd /s /q %%i\ndel /s /f /q C:\\Windows\\Temp\\*.*\n```\n- First line with `for /D` removes all **subdirectories** inside `C:\\Windows\\Temp`, recursively (`/s`) and quietly (`/q`).\n- The `del` line removes all files under `C:\\Windows\\Temp` (including nested because of `/s`), forcing deletion, quietly.\n\n```\n:: Delete user Temp files\necho Deleting User Temp...\nset TempDir=%Temp%\nfor /D %%i in (%TempDir%\\*) do rd /s /q %%i\ndel /s /f /q %TempDir%\\*\n```\n- `TempDir` is set to your current `%Temp%` environment variable.\n- Then it deletes every subdirectory in `%TempDir%` (which is your user\u2019s Temp folder or possibly another temp path), and all files in that directory.\n\n```\n:: Optional: log\necho Cleaned on %DATE% %TIME% >> C:\\scripts\\cleanup.log\n```\n- Appends a timestamped \u201ccleaned\u201d message to `C:\\scripts\\cleanup.log`.\n\n---\n\n## If your user directory is `C:\\Users\\nick`, will the user temp folder (`%Temp%`) be cleaned?\n\nYes \u2014 **almost certainly**, provided the script is running under your user account (or under SYSTEM but with `%Temp%` pointing to your user\u2019s temp folder). Here\u2019s how:\n\n- On Windows, `%Temp%` is an environment variable that usually maps to `C:\\Users\\<username>\\AppData\\Local\\Temp` for a regular user, e.g. `C:\\Users\\nick\\AppData\\Local\\Temp`.\n- The script does `set TempDir=%Temp%`, then removes all subfolders and files inside `%TempDir%`. So everything inside your user %Temp% folder is removed when the script runs with that environment variable.\n\n---\n\n## Important caveats & details\n\n- **Running as SYSTEM vs running as your user**: If Task Scheduler runs the script as **SYSTEM**, `%Temp%` might resolve differently. On recent Windows builds, SYSTEM\u2019s temp directory is something like `C:\\Windows\\SystemTemp`. There's a Microsoft update that changed behavior: when running as SYSTEM, `GetTempPath()` returns `%WINDIR%\\SystemTemp`. ([support.microsoft.com](https://support.microsoft.com/en-au/topic/gettemppath-changes-in-windows-february-cumulative-update-preview-4cc631fb-9d97-4118-ab6d-f643cd0a7259?utm_source=openai))\n\n- **Locked files/folders**: Files that are in use (locked by some process) cannot be deleted. The script may silently skip them if deletion fails (because of `/q` quiet mode). It won\u2019t necessarily halt or report which ones failed.\n\n- **Prefetch**: Deleting everything in the Prefetch folder is possible, and Windows will re-generate necessary `.pf` files. But it will slow down application startups and boot processes temporarily until the folder repopulates. ([makeuseof.com](https://www.makeuseof.com/windows-prefetch-files-explanation/?utm_source=openai))\n\n- **Risks**: Usually low, but:\n  - If `%Temp%` or subfolders are used by currently running apps/installer/etc., those files could fail deletion and cause unexpected behaviors.\n  - Removing prefetch data removes Windows\u2019 optimizations; performance suffers until rebuilt.\n\n---\n\n## Summary\n\n- What it removes:  \n  \u2022 All files in C:\\Windows\\Prefetch  \n  \u2022 All files and subdirectories in C:\\Windows\\Temp  \n  \u2022 All files and subdirectories in the current `%Temp%` directory (user temp by default)\n\n- For user \u201cnick\u201d with `C:\\Users\\nick`, yes \u2014 the `C:\\Users\\nick\\AppData\\Local\\Temp` folder contents will be cleared, if `%Temp%` is set to that (which is standard) *and* the script is running with permissions to access it (usually true if elevated or SYSTEM).\n\n- Performance impact:  \n  \u2022 Slight slower boots and app launches initially until cache/prefetch info rebuilt.  \n  \u2022 Free space reclaimed; clutter removed.  \n\n- You want to ensure:\n  - The script has correct permissions.\n  - Task Scheduler is using correct account context (SYSTEM vs user).\n  - `%Temp%` environment variable is pointing where you expect.\n  - Errors are acceptable or logged if needed.\n\n---\n\nIf you like, I can help you adjust the script so it\u2019s tailored to only clean specific user temp (e.g. only `nick`), or skip use with SYSTEM so as not to affect other users. Do you want to do that?"

        "content": "If the script is running under the **SYSTEM** account and there's only your user \u201cnick\u201d on the system, *likely* it **won\u2019t** clean out `C:\\Users\\nick\\AppData\\Local\\Temp` using `%Temp%` as you expect. Here\u2019s why, based on how Windows handles `%TEMP%` for SYSTEM versus regular user accounts:\n\n---\n\n## How `%Temp%` works under SYSTEM\n\n- When processes run as the SYSTEM account, Windows often uses a different temp directory than the regular user\u2019s `%Temp%`. ([security.stackexchange.com](https://security.stackexchange.com/questions/252734/windows-directory-that-is-only-accessible-by-system-user?utm_source=openai))  \n- Traditionally, for SYSTEM, `%TEMP%` is set to either `C:\\Windows\\Temp` or something like `%WinDir%\\System32\\config\\systemprofile\\AppData\\Local\\Temp`. ([security.stackexchange.com](https://security.stackexchange.com/questions/252734/windows-directory-that-is-only-accessible-by-system-user?utm_source=openai))  \n- There is also a recent update (as of **February 2026**) introducing a new folder `C:\\Windows\\SystemTemp` for processes running under SYSTEM, for security improvements. ([opswat.com](https://www.opswat.com/docs/mdcore/troubleshooting/windows-temporary-folder-path-changes-for-system-account?utm_source=openai))\n\n---\n\n## Why your `C:\\Users\\nick\\AppData\\Local\\Temp` might **not** get cleaned\n\nGiven that:\n\n1. The script sets `TempDir = %Temp%` based on the environment variable **as the SYSTEM account**.\n2. Under SYSTEM, `%Temp%` will not typically point to your user\u2019s AppData\\Local\\Temp directory. It will use SYSTEM-specific temp path. ([security.stackexchange.com](https://security.stackexchange.com/questions/252734/windows-directory-that-is-only-accessible-by-system-user?utm_source=openai))\n\nSo even if \u201cnick\u201d is the only user, since the script is running *as SYSTEM*, `%Temp%` will reference the SYSTEM account\u2019s temp directory, *not* your user's.\n\n---\n\n## So what *will* happen\n\n- The script WILL still clean up:\n  - `C:\\Windows\\Prefetch`\n  - `C:\\Windows\\Temp`\n  - SYSTEM\u2019s Temp directory (as resolved via `%Temp%` under SYSTEM) \u2013 which could be `C:\\Windows\\SystemTemp` or `C:\\Windows\\Temp` or the `systemprofile\\AppData\\Local\\Temp` path. ([opswat.com](https://www.opswat.com/docs/mdcore/troubleshooting/windows-temporary-folder-path-changes-for-system-account?utm_source=openai))\n\n- The script WILL NOT clean out `C:\\Users\\nick\\AppData\\Local\\Temp` unless:\n  - The script is run *under your user account* (not SYSTEM), so `%Temp%` resolves to your user\u2019s temp folder.\n  - Or, you modify the script to explicitly point to `C:\\Users\\nick\\AppData\\Local\\Temp\\*`.\n\n---\n\n## What you can do if you *want* to clean your user temp folder\n\nHere are options:\n\n- Modify the script to reference your user's temp folder explicitly, for example using:\n\n  ```\n  del /s /f /q C:\\Users\\nick\\AppData\\Local\\Temp\\*.*\n  rd /s /q C:\\Users\\nick\\AppData\\Local\\Temp\\*\n  ```\n\n- Or run the script under your user context rather than SYSTEM. If you schedule it as a \u201clogon\u201d trigger for \u201cnick\u201d rather than system startup under SYSTEM, then `%Temp%` should be your user\u2019s.\n\n- Combine both: keep system-level cleanup, *and* schedule a user-level cleanup for `C:\\Users\\nick\\...`.\n\n---\n\nIf you like, I can help you rewrite the script so it cleans both SYSTEM temp and your own user temp folder safely. Do you want that version?"

Without this, SCRIPT running as SYSTEM won\u2019t remove your AppData temp.
