If your having a slow sluggish computer this may work or it may not for you, but it typically works for me. I simply go to TASK MANAGER and delete anything thats new on TM for the last few days when the computer started getting slow.

For example if your computer has been running slow for the last 3 days..go to TM..background processes right click properties and look at the dates, many times if you see things new on the TM from NOV 1st 2nd 3rd, or late October..it could be the reason for the slow PC.

Just thought i'd share that, as people never mention it on various tech forums.
