always a small window 296x31 and cannot be resized

[feiteng]

always a small window 296x31 and can not be resized. after the upgrade virtualbox, all virtual machines stopped working resizing. remove the "Guest Additions" not helps. option "adjust windows size" reduces the virtual machine window to 296x31, any attempt to stretch unsuccessful.

when "Guest Additions" not installed, possible to adjust window manually, but very soon it become 296x31 and scrolls visible.

option "adjust windows size" make a very small window with scrolls even if "Guest Additions" not installed.

sorry for bad english.

Please attach a VBox.log file for such a VM session.

Out of curiosity, are you running a genuine copy of Windows 7? To fix your problem, you need to run sfc /scannow in an elevated Command Prompt, followed by a reboot.

sure, i use genuine copy of windows 7 x64 home with serial key on bottom of my laptop. software protection service was disabled for prevent send private data to microsoft. but that was long time ago. sfc not helps. also, i found that fullscreen use of virtual machines still possible.

Have you run sfc /scannow?

Same situation on new pc, clean windows 7 x64 build 7601, clean virtualbox installed. I found another option, use detachable start mode. But normal start of virtual machines - same problems.

Please provide a VBox.log file when you started your VMs with VBox 5.0.22 and try to resize the guest windows which fails.
