NetSupport is not part of Windows; it is third‑party remote‑control/management software that was likely installed by an organization (school, employer) or bundled with other software. The error appears because something is still trying to start NetSupport and read its configuration file (client32.ini), but that file or the whole product has been removed or corrupted.
To stop the popup, remove or disable the leftover NetSupport startup entry or scheduled task instead of trying to recreate the missing file. Typical approaches are:
- Uninstall NetSupport (if still installed)
- Open Settings → Apps → Installed apps.
- Look for entries such as “NetSupport School”, “NetSupport Manager”, or similar.
- If found, uninstall them. This usually removes the startup entry and stops the error.
- Disable NetSupport from startup
- Press Ctrl+Shift+Esc to open Task Manager.
- Go to the Startup tab.
- Look for any NetSupport‑related entry (publisher often shows “NetSupport Ltd” or similar).
- Right‑click it and choose Disable.
- Restart Windows and confirm the popup no longer appears.
- Check Task Scheduler for leftover tasks
- Press Win+R, type
taskschd.msc, press Enter. - In Task Scheduler Library, look for tasks with names or descriptions mentioning NetSupport, 0drive, or owedrive.
- If found and NetSupport is no longer needed, delete or disable those tasks.
- Press Win+R, type
- If installed by an organization
- If the device is managed by a school or company, NetSupport might be required for remote support or classroom control. In that case, contact the organization’s IT support; they can either repair the installation (so the file is recreated) or remove the product cleanly.
Once the startup entry or scheduled task that calls NetSupport is disabled or removed, Windows will stop trying to read client32.ini, and the dialog box will no longer appear.
