Downloaded Windows Repair Portable 4.0.0 today and have been running the repairs. At present, repair job 18, Repair Volume Shadow Copy Service is running as it has been for the last 2 hours. This repair apparently did finish one part of the repair "Decompressing & Updating windows Permission file", this part of the job taking 0.14 seconds, and now all it says is "Running Repair under Current User Account".
I've used various versions of Windows Repair for years, often running it on friends computers that need repair, and just downloaded version 4.0.0 (portable) today and decided to run it to see if it is different than previous versions. Yes, previous versions have been slow, mostly on older computers, but the computer this is running on is quite fast.
I shall continue to allow Windows Repair run on the computer until I hear from somebody that it is safe to stop the program from running on this repair or that 2 hours is acceptable and to continue to let it run.
Thanks
