Apparently there´s no more crashes. So the gadget platform "sidebar.exe" just doesn´t work.
1. If Daemon Tools Gadget is installed then sidebar.exe won´t close during a shutdown.
2. If certain Windows Updates are installed the PC can not go into hibernation.
3. Sometimes the gadgets make the Windows Experience Index for aero graphics drop 1.2 point.
4. Occasionally sidebar.exe won´t respond during startup and none of the known fixes for it works.
5. Occasionally the system crashes regardless of what program is currently running.
Seems like Windows 7 is performing 100% now after uninstalling the gadgets feature in Windows so all together there´s only 4 problems with running Windows 7-64b on Aspire R7:
1) Windows 7 setup will freeze loading disk.sys if booted in UEFI mode. Probably it has to do with the harddisk being an SSD. So the system drive can´t be GPT formatted. Not that more partitions would have mattered. But when comparing MBR to GPT on the two connected external USB3 drives, there hasn´t been a single failure found by CHKDSK after converting to GPT some months ago. So it would have been nice with GPT on the system drive also.
2) Windows Event Viewer repeatably reports: ACPI error 10 - BIOS is attempting to write to an illegal PCI Operation Region (0x38). It´s just a BIOS flaw that Windows is blocking.
3) The Acer application/driver for the sensor module is incompatible with Windows 7. Only important if you need to rotate the screen and want it done automatically.
4) The Windows gadget platform is very buggy. After re-installing Windows five or more times with different copies of Windows, it just doesn´t work.
Alternatives to the gadget platform is: If you unlock the taskbar and make it wider, it can show both time, weekday and date; and there are programs which can display fx GPU temperature as overlay on fullscreen.
