I have been working on a PC that was rendered inoperable because svchost.exe pegged the CPU @ 100%. After working on it for a couple of hours, I reformatted the HD & restored the OS. In the process of re-installing programs, when I got to the Adobe products (Flash, Shockwave, Air & Acrobat reader) again svchost.exe was pegging the CPU @ 100%. So I removed the 4 above mentioned & restored the PC to just before the installation, and the PC was back to normal. Next I re-installed Acrobat reader, and svchost.exe pegged the processor again at 100%. After removing Acrobat reader & going back to the restore point, everything was normal again. The next time I tried just the Flash & Shockwave players, and pegged again. Would draw the same conclusion as me that there is a problem with the Adobe downloads? I have another PC on my bench that seems to have the same problem. If there is anyone from Adobe that would like to address this issue please contact me. firstname.lastname@example.org
This is a user-to-user forum, and it is very unlikely that someone "from Adobe" will contact you. It is not recommended that you post your email address in a public forum, as it will only attract spambots.
The fact that svchost is using high CPU resources (without any of the Adobe products actually running) indicates to me that you have something in your startup items that triggers svchost usage. Examine your startup list and eliminate anything that could doing that.
