Bests & Worsts Reviews from Amazon

I bought the 5 user license from Amazon. I like the way Amazon keeps my software subscriptions for me. I install PCMatic on 2 of my laptops and it performs great. The software cleaned up my registers, removed some stuff I had no idea I had, etc... I always believed that I kept my PCs clean, and I do, but PCMatic found some problems and fixed them. These two PCs are running noticeably better now also. Both these PC's are running Windows 10. However, I tried installing PCMatic on my son's PC which is about 6 months old.It was upgraded to Windows 10 also. However, I can't get PCMatic running on this PC. I don't have the error in front of me know but from memory, it was a DLL problem. I plan on installing a copy on my wife's laptop. Her PC is lagging and having problem. I believe PCMatic will correct this PC's problems as long as it installs. This is a Windows 8.1 laptop. Stay tuned.
