6 Ways to Fix the KERNEL_STORAGE_SLOT_IN_USE Error

The KERNEL_STORAGE_SLOT_IN_USE bug check with a value of 0x00000199 indicates that the storage slot can’t be freed as it is in use. This error usually occurs when there is a conflict between hardware drivers, missing or corrupted system files, or third-party software issues.

To begin with, restart your computer, as this will resolve temporary glitches if present. Then, check for Windows updates, as they could have patches to fix the kernel storage issues, and run a malware scan using a reliable antivirus tool. You can also check for BIOS/UEFI firmware updates.

How can I fix the KERNEL_STORAGE_SLOT_IN_USE error?

1. Update the device drivers

1. Press Windows + R to open the Run window.
2. Type devmgmt.msc and click OK to open the Device Manager app.
3. You will get the list of system components; click each category one by one to expand and look for a problematic driver with a yellow triangle and an exclamation mark inside.
4. Once located, right-click the driver and select Update driver from the context menu.
5. Select Search automatically for drivers, then follow the on-screen instructions to complete the process. Repeat these steps if there is more than one problematic driver.

Windows will try to find the best version of the driver; however, if it fails, head to the manufacturer’s website and install the latest version. Alternatively, you can download and install a reliable driver updater tool, to ensure that all the system device drivers are up to date.

If the device drivers are already up to date but you are still experiencing the issue, you need to reinstall the affected drivers.

1. Launch the Device Manager again, expand the category, right-click the driver, and select Uninstall device from the context menu.
2. Click Uninstall to confirm the changes.
3. Go to Action, then click Scan for hardware changes.

2. Run SFC & DISM scans

1. Press the Windows key, type cmd in the search box, and click Run as administrator from the list of options to launch Command Prompt with elevated rights. 
2. To scan and repair the corrupted system files, type the following command and hit Enter: sfc /scannow
3. Wait for the scan to complete, then copy & paste the following command to repair the system image files and press Enter: Dism /Online /Cleanup-Image /RestoreHealth
4. The scan will take some time, wait for it to execute successfully, then reboot your PC to let the changes take effect and see if you get the KERNEL_STORAGE_SLOT_IN_USE error again.

3. Scan for disk errors

1. Press the Windows key, type cmd in the search box, and click Run as administrator from the list of options to launch Command Prompt with elevated rights. 
2. To find and fix the disk errors and bad sectors on RAM, type the following command and hit Enter: chkdsk /f /r
3. If your device is in use, you will be prompted to schedule a restart on your computer; type Y and hit Enter to proceed.

Restart your computer. The scan will start and look for bad sectors on your RAM. If issues are found, try resetting your RAM and rerunning the scan. If the problems persist, you need to replace the faulty RAM.

4. Restore your PC to a previous version

1. Press the Windows key, type control panel in the search box, and click Open from the list of options. 
2. Select Large icons for View by and choose Recovery.
