На ноутбуке пропал двд-привод в меню "мой компьютер". В чем может быть причина?

pusk - potom najimaem na "Vipolnit" a tam nabiraem slovo "regedit" i vibiraem etu kategoriyu bez oshibok. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11­CE-BFC1-08002BE10318}
a tam udalyaem "Upper filter" ili "Lower filter"
a potom zakrivaem vsyo i restart windows..
provreno rabotaet..

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11­CE-BFC1-08002BE10318}

Apparently it seems that this is an age old fix for even XP systems. If
you venture to the registry key above by doing the following steps:

Click on the start menu.
If this is a Vista machine in the search box type in “regedit” without
the quotation marks.
Maximize the HKLM and then go ahead and browse until you reach the key
listed above.
In the right panel you’ll see something along the lines of “UpperFilter”
and “LowerFilter” you want to click on each “filter” key and hit delete.
Click yes when it asks to confirm if you wish to delete the key.
Restart Windows.
