Removing the device in Device Manager is not the same as deleting its driver package: the second action can leave the reader without a driver until a suitable one is installed.
What happens when you uninstall a Realtek card reader?
Windows removes the device’s current installation or association. The reader may disappear from Device Manager, and cards inserted in the built-in slot may no longer be detected. If Windows still has a suitable driver package, it may rediscover the reader or reinstall the driver after a restart. That recovery is not guaranteed for every PC.

Microsoft advises physically unplugging a device before uninstalling it, but that instruction applies most directly to detachable hardware; a laptop’s built-in reader usually cannot be unplugged in an ordinary user workflow. Microsoft also recommends creating a system restore point before changing device drivers. See Microsoft’s Device Manager guidance.
What’s actually slowing this PC down?

Uninstalling the device is different from deleting its driver
In Device Manager, Uninstall device removes the device installation. The separate Delete the driver software for this device option removes the driver package from Windows’ driver store as well. If no other matching package is available, the reader cannot work until a compatible driver is installed. Administrator privileges may be required to delete the package, and a restart may be needed.

Do not select the delete-driver option as routine cleanup. Windows Update may reinstall a necessary missing driver, but permanently preventing that requires additional driver-store and Windows Update changes. That is advanced driver management, not a necessary step for ordinary troubleshooting.
Should you uninstall it?
If the reader works and you have no specific troubleshooting reason to remove it, leave it installed. If you are diagnosing a problem, uninstalling the device without deleting its driver package can be a reasonable step; Windows may detect it again after a restart. Avoid removing a Realtek entry until you have confirmed it is actually the card reader: Realtek supplies drivers for multiple hardware categories, and names can be similar.

How to restore a reader that stopped working
Let Windows redetect it
Restart the PC and check Device Manager. Microsoft says Windows attempts to reinstall a driver after restart, though automatic recovery depends on the available driver and device. Its driver update guidance also describes using Device Manager’s automatic or manual update options if the device remains unavailable.

If Windows does not restore the reader, check the computer maker’s official support page for the specific PC model. Microsoft recommends consulting the device manufacturer’s site when Device Manager recovery does not work and warns against unofficial driver-download sites.

Realtek’s official catalog lists a PCIe card-reader driver for Windows 10 and 11, version 10.0.26100.21378, updated 2025-01-15. That listing does not establish that this is the right driver for every built-in reader: the PC’s hardware and manufacturer-specific configuration matter. Realtek’s catalog also separates USB smart-card (CCID) and legacy USB card-reader drivers from the PCIe category.
A Microsoft Update Catalog entry illustrates the need to match hardware and Windows version: Realtek USB 2.0 Card Reader driver 10.0.22621.31282 is dated 2023-05-31 and listed for Windows 11 Client version 22H2 and later with hardware ID USBVID_0BDA&PID_0129. It is not a universal driver recommendation for all Realtek readers. See the Microsoft Update Catalog record.

When an external USB card reader makes sense
A separate USB SD card reader can work around an unusable or unwanted built-in slot. The SD Association describes detachable reader setups such as a dongle or docking station, but that category-level example does not establish the compatibility or performance of a particular product. Before choosing one, check:
- Whether it supports the card format you use, such as SD or microSD.
- Whether its USB connector fits a port on your computer, or whether an appropriate adapter is needed.
- Whether the reader supports your operating system.
- Whether keeping a separate accessory is more convenient than restoring the built-in slot.
The SD Association’s Realtek presentation on card-reader use cases depicts detachable USB-reader scenarios; it is not a product recommendation. Compatibility, speed and price depend on the specific reader and computer.

Check before removing any Realtek device
Not every Realtek device entry is a card reader. Confirm the name, category and, when available, hardware ID before uninstalling or deleting a driver package. The correct recovery path depends on the PC model, Windows version and actual reader interface; a driver listed for one Realtek card-reader category may not match another.
