Hi there and welcome
Can you close all programs please
Then press the windows key + R and enter in
In the window that opens, delete all the files listed there. These are temporary files, not system or your files.
If windows says a file is in use when doing this, you can skip it.
Then press the windows key + X and click on Command Prompt (admin)
A black window will open.
Type in it
press enter and when it has completed, type in
It will give a message "the type of the file system is NTFS cannot lock current drive.
chkdsk cannot run because the volume is in use by another process. Would you like to schedule this volume to be checked the next time the system restarts y/n" Say Y, press enter and restart the computer.
Please note, while this normally only takes 10 minutes to run, it can take at times number of hours if windows encounters many issues. If this is occurring it is critical to let this complete as it means you have corruption on the hard drive that it needs to fix. Even if it looks like the scan is not progressing, it is, please just let it run to completion. Windows will then start when it has.
Then tell me if it now works please.
