Windows 7 RC will be available until Aug. 15.
Muzes si stahnout a nainstalovat Release Candidate verzi, ta bude fungovat az do 2010. nicmene budes muset udelat cistou instalaci, pokud nepouzijes upravu popsannou na

However, Microsoft did publish instructions on how to work around that block; the fix requires editing of the Windows registry.
The other option for Windows 7 Beta users is to revert to the operating system they were running before installing the preview, presumably Windows Vista or XP. That, however, also requires a clean install of the older operating system.
muzes zpatky nainstalovat puvodni operacni system.
Jinak hledej na netu... mam pocit ale ze tenhle problem te potka za cas zase

nezapomen ze to jsou betaverze.. po vydani finalni verze prestanou postupne fungovat a budes se muset bud vratit k drivejsimu systemu (windows xp, windows vista) nebo koupit Windows 7.
