start up

i have 2 p.c.'s. both windows 8.1, when i first install cis everything works great. after approx. 3 months i have no problem going on dragon from the desktop but, to get virtual desktop to open it takes 10 minutes for it to open. at first i thought it was start up…i went in there and stopped everything i could to see if this was the problem. the problem was still there so i ran endpoint cleaner, malware bytes ect. this problem still exists. i know from the past i can uninstall cis then re install and everything willl be good,for awhile. i have many files i do not wish to loose so any help would be appreciated , thanks…i also emptied sandbox and that diddent change how long it took for virtual desktop to open
