PROBLEM SOLVED (see below)
It all started 2 days ago, without any program or voluntary change made on the computer (Windows hidden updates excluded). All of a sudden my laptop would take between 45minutes and 1 hour (!) to fully boot, because it is hanging over the network connections.
While it is doing that, many programs wouldn't start, including a lot of internal Windows software like Device Manager and so on. Once the computer is finally connected, everything works fine and quick as usual, although some times one between the wireless
connection and the LAN would not be available. After trying many things, I realized that Windows did two critical updates. Astonishingly, the only cure for my computer is now to restore Windows to a point prior to the updates. Problem solved? No, because if
I don't prevent Windows from automatically updating the problem comes back full power. Otherwise the machine is working well again without updates (average full booting time is 20s). Does Microsoft plan to solve this bug?
Little update:
I did not solve the problem, but it represented itself several times. No worries (or yes?), the restore does still prevent it. But the settings that prevent Windows to perform automatic updates are kind of bad, as Windows DOES UPDATE also if I set it as to
"download automatically but ask me to install". So I had already twice the computer stalling again on network connections, and later (after the hour to resume) found out that although widows update history doesn't show any Windows update installed the same
day, the system restore has a new restore point dated right after the system restore, so that the next time I would switch on the computer I'll have to wait my good hour for using it. I don't like to criticize Windows, but this kind of pissed me off. Now the
settings are on "ask me to download and to install", and the update it has been installed anyway (I don't get it, why bothering asking what I want if then it all happens differently?).
I am forced to switch to hibernation instead of switching off the machine, as like this I will save 2 or 3 hours of my working day.
For the records, the updates that are apparently waiting to be installed on my PC are:
Important
Service Pack 2 for Microsoft Office 2010 (KB2687455) 32-bit Edition
Optional
Intel - Other hardware - Intel(R) Management Engine Interface
Update for Windows 7 for x64-based Systems (KB2574819)
Update for Windows 7 for x64-based Systems (KB2592687)
Update for Windows 7 for x64-based Systems (KB2709981)
The important one should be the one that gets installed, but in the system restore point list it says "Windows update - Critical Update"
Few more technical details
My laptop:
Samsung NP900X3C
Intel Core i7-3517U CPU@1.90GHz-2.40GHz
RAM 4.00GB, SSD 256GB
Windows 7 Professional SP1 64-bit
Tried but failed procedures:
- Change the network (home or at work is the same, wireless or cable LAN too)
- Change the IP address for LAN
- Update drivers for network card (Realtek PCIe GBE Family Controller)
- Disable possible disturbing Startup services (there were no new services)
- Boot in Safe mode with networking (also like this there is the very same problem)
- Scan for viruses (Microsoft Essential could not find any threat)
- Scan for malware (Malwarebytes anti-malware software detects 18 threats, but after their removal Windows would not boot at all. On top without removing them my computer is running and happy now without the updates)
- Restore to a point prior the updates and then allow the Windows critical updates to be installed ("Pasteur" prove of cause-effect)
Look which services are running on Startup to find the one on which Windows is hanging (doesn't work since the computer is stalling and the services list cannot be accessed)
- Clean up the registry (Eusing Free Registry Cleaner detects some errors, but this does not solve the problem)
- Check up in task manager if there is a program taking all the computing power (no programs running, and if I play too much with task manager it would freeze. By the way the CPU usage is at 0-5% and the memory usage is around 600MB)
- Update all the possible drivers available at Samsung website
- Stop the antivirus (Microsoft Essentials does not actually manage to start the Real-Time protection before the networks are on. And without the updates there is absolutely no problem with it)
PROBLEM SOLVED!
Here how it did work for me, although I'm not sure all these steps are required (and I don't have time to investigate):
- Restore the computer to a point just after the problem occurred (I couldn't go earlier)
- Uninstall Cisco Anywhere Connect
- Hide the optional updates (KB2574819, KB2592687, KB2709981 and the Intel driver update)
- Install the Office 2010 SP2 update
- Reboot the computer (wait the usual 45min-1hour)
- Install the Microsoft Security Essential last update from MSE (159.663.0) directly from MSE (not from Microsoft Update, again no idea if this does help)
- Reboot the computer again... done! Reboot in 20 seconds
- Now reinstall Cisco Anywhere Connect (I need it for work)
- Check rebooting... 20 seconds!
