Windows 7 is slow to boot and svchost is using 50% cpu
Hi,
i have this Win7-64b desktop with all latest updates installed and pretty recent hardware. But it is running very slow. Symptoms are:
- after boot + autologon the system is unresponsive for at least 15 minutes. Showing a sort of flashing desktop, no response on mouse or keyboards actions.
- after the 15 minutes, the system becomes responsive but 50% CPU is used by scvhost.exe all time long. The high cpu is due to the update service. If I stop this the cpu goes down to say 0%.
- important (windows) updates install ok, but the optional updates fails to install. The install starts but then just hangs on downloading, without any visible progress.
What is the cause/solution for this?
