Never change a running system ....

Well, even I have let myself be blinded by the Windows 7 hype and ordered the OEM version after I leave the testing of Windows running on Win7 capability and has shown no problems (up to age on installed software).
So during the weekend already WSIN7 premium on my almost 6 month old HP computer (to be sold in this configuration, even today!) Installed.
Installation proceeded without major problems and relatively quickly.
After installing a lot to me that unlike before, the system has become relatively slowly, even the Fensteröffnen- and close in IE took ....
Then there appeared the error message: "Missing drivers coprocessor". Aha, so maybe that thingy was so slow. There was also a link to the HP website displayed under which the driver is runterladbar. Really great, the new Windows, I thought.
The download worked nedlich after calming hour mark. When you run the program, unfortunately, came the error message that the file is not compatible with my operating system version .....
That the memory slots for SD and similar Larten also no longer showed up in My Computer, I found there then no longer a big deal.
So beautiful again be playing the old Vista .....
My final opinion: Soo bad as all allege Vista is (at least according to the service packs!) Does not determine and soo amazing how all is claiming Win7 even less .....
