Thank you for the reply. Having a registry backup didn't matter as the computer ran extremely slow and crashed on attempted fixes. Had to ensure all files were backed up and then have Microsoft wipe the OS and reinstall. Apparently Ccleaner indiscriminately deletes Windows OS files. I also have been told that it increases the number of ads that appear in browsers. I will no longer use Ccleaner.

This afternoon I ran the cleaner, as well fixing registry issues. Now Windows 10 is extraordinarily slow on restart and other functions. I also now have MS Office error code 0x426-0x0. I cannot run any Office programs and have tried solutions presented online, which have not worked. Can someone please help? Thank you.
