Windows 10: Windows 7 PC Suddenly Very Slow and Semi-Non-Functional

Hello,When I started up my computer today, it took much longer than usual to boot up and load the desktop. When I open "My Computer", at first all unused drives show up. After closing and reopening, the normal drives are listed, but my B: drive on which I store all my precious documents, pictures, etc. does not have the bar underneath showing the used/available space, and it is not accessible. I am able to access my other drives A: and C: normally. Sometimes, "Computer" just shows a blank screen while the green loading bar at the top slowly creeps along, never reach

Suddenly Windows 10 see my dvd writer but non that much.

I have been googling to find hints about the problem I'm experiencing, but the complication has survived some fixing attempts. Here I refer to Microsoft Windows [Version 10.0.17763.107] and TSSTcorp SH-222AB CD DVD writer. Product's drivers are not available on manufacturer' s web site Home - ODD Support English Toshiba- Samsung Download CenterODD Support English . Any advice will be very welcomed ! Thanks !

STEP 1
All of a sudden, File Explorer's left panel can't see the DVD driver, but the one on the right can. See fig. 1 and fig. 2 .







STEP 2
HWiNFOPortable_6.08.3830 detects the device as TSSTcorp SH-222AB. See fig.3.




STEP 3
Other file managers see the device. See fig.4, fig.5, fig.6.










STEP 4
When I insert a DVD in the driver and try to access it i get an error message: "Please, insert a disk." See fig. 7.




STEP 5
The Controller AHCI SATA works fine, fig. 8 and 9. Anyway I have disinstalled and reinstalled it, see fig. 8 and fig. 9.







STEP 6
I haven't been given any options regarding the DVD driver, see fig. 10.

 

Windows Update suddenly hangs?

Windows Update is suddenly hanging for some reason... I went and downloaded and installed the first bunch of updates, restarted when asked, and now when I go back to windows update I just get the window with a white box forever. Reboot and it still does it. This happens to be on my main machine, running windows 7.

I've also noticed when I reboot it says configuring windows update, step 3 of 3, 47%. Maybe it somehow skipped something and is screwed forever?
