This news may be old hat to many of you, but it was a pleasant surprise to me, so wanted to share it.
My Win7 64-bit computer was freezing every now and then, for no explainable reason, but I simply put up with it, as various corrective steps failed to help.
Then I noticed that my Internet Explorer v10 was not playing friendly with the online Internet screens for my bank and credit union (appeared to be partially adobe related). Switching back to IE9 and IE8 did not work; instead they totally goofed up my IE browser to the point it would not connect to anything any more.
Well, after unsuccessfully trying to reinstall IE, I tried to do a Win7 repair using my original install CD. Apparently that option is not available, unlike earlier Win versions, so I instead chose to reinstall Win7 using the upgrade option versus a clean install. It took a long time, but lo and behold - it gave me a clean resinstall of Win7, and ALL of my existing software programs were still installed and working. All I had to do was download and install some Win7 software updates. Not having to reinstall (and then configure) all of my software, plus not losing recent data files was a real blessing.
Now I no longer have random machine freezes, and I have stuck with IE8 so I can safely access my online financial info from the banks & credit unions.
