Since earlier this week, my laptop becomes unresponsive when logging into windows. Disk C: is always at 100%. Windows will only be usable and lag free after around 15 mins. Open Resource Monitor shows me that these are usually the causes: pagefile.sys, softwaredistribution/datastore, app/data/local/comms/unistoredb/store
Also, my shutdown and boot times are prolonged. Booting would take 20 mins or more. The screen would get stuck at the manufacturer logo and the loading of windows.
I have already disabled windows apps from running in the background, disabled superfetch and windows search.
I have run full anti-virus scans and chkdsk scans, but they don't report any problems.
Logging onto different windows accounts doesn't solve it. I also removed my windows account and emails (mail and calendar apps)
All my drivers are up-to-date as well.
The last solution i haven't tried is doing a reset but as much as possible, i don't want to lose my installed programs
My machine: i5 processor, 4gb RAM, 1TB hard drive (Drive C: 209/372 GB, Drive D: 156/537)
