XP Appearance Gone / No Audio Playback / All System Restore Dates Gone

Hello,

I first noticed that the standard XP Appearance had changed on my system. I then noticed that the XP Theme was missing from my system. I thought of doing a system restore, but I had lost all previous System Restore dates...

In addition to these issues, my system has lost audio playback and previously installed printers. It seems my system has also lost the ability to install printers or uninstall/ install applications...

A Windows Update was recently done, but these issues did not start directly after the Windows Update.

Any help regarding the reason for these issues or a solution to them would be greatly appreciated.

Thank you in advance!
