Would appear not.
I have unoppened Memorex Recordable Media CD-R 700 MB 52X 80min CDs and don't know if these will work on my new computer which runs with Windows 7 Home Premium 64bit.
Don't want to break the seal on this back of 100 CDs. If I can't use them I shall put them on e-bay. But in the meanwhile don't know what to do with them.
Hope this additional information helps those who are prepared to offer advice.
